Skin can be divided into epidermis, dermis and subcutaneous tissue, plus skin accessory organs with special structure and function, such as hair, nails, fat glands and sweat glands, which are collectively called skin derivatives. Epidermis is a tissue with vigorous metabolism, and new cells in epidermis are constantly replaced by new cells every day, which are divided into five parts from bottom to top: basal layer, spinous layer, granular layer, transparent layer and stratum corneum. The function of epidermis determines whether the skin is healthy and beautiful. Dermal tissue provides nutrition and elasticity for the skin.

The normal metabolic cycle of epidermis takes 28 days. Skin care can not only focus on the immediate effect, but how to continue it is important. Therefore, it is not advisable to emphasize quick results. It is important to maintain it regularly every day.

The texture, moisture, transparency and protection of skin are mostly determined by the stratum corneum. Skin care is also to pursue a healthy stratum corneum. The cells in the stratum corneum have no nuclei, but are stacked together to form a thin sheet with a thickness of about 0.02-0.03cm, which is responsible for maintaining the physiological function of the skin and preventing foreign invasion.

The horny surface of the skin contains a slightly acidic natural sebum film. It is mainly composed of secretions from sebaceous glands and sweat glands. Its function is to moisturize the skin, reduce water loss, and resist the damage and invasion of harmful substances from outside. The type of skin depends on the soundness of stratum corneum and sebum membrane, that is, the balance between sebaceous gland secretion and stratum corneum moisturizing. Oily skin means excessive oil secretion, while dry skin means insufficient oil secretion, resulting in water loss.

Keratin, moisture and oil constitute the protective film of the skin. Healthy skin, cutin, moisture and oil are in an excellent balance, which can keep skin moisture and resist external stimuli. On the contrary, once the sebum membrane of the stratum corneum is destroyed, the skin will not be able to maintain its normal physiological function.

■ The essence of skin is not static.

Everyone's skin is influenced by congenital genetic factors and acquired factors. Acquired factors include environment, climate, age, diet, drugs and so on. So the skin condition will change with the seasons. In summer, the secretion of sebaceous glands and sweat glands of the skin is relatively increased, making the skin oily. In autumn and winter, with the decrease of temperature and humidity, the original oily skin may be improved and become neutral skin. However, people with neutral skin may become dry and peeling when they are blown by cold air. Therefore, we must carry out correct maintenance according to the changes of internal and external environment to keep the skin in the best condition.

Moisturizing function of skin:

Everyone's skin is mainly determined by the moisture content and sebum content of the stratum corneum. The stratum corneum on the skin surface usually needs to maintain 15%-20% water content to make the skin feel comfortable. However, if the skin wants to have the so-called crystal clear feeling, the moisture content of the stratum corneum must be between 20% and 35%.

A layer of natural sebum membrane composed of sebaceous glands and sweat gland secretions is attached to the surface of human skin, which can prevent skin from losing water and isolate external stimuli. When this protective film is imperfect or insufficient, the skin is prone to dry itching and allergies.

Once the stratum corneum of the skin is unhealthy, the coagulation power of keratinocytes will become worse. Even if a lot of water is added, the water will evaporate quickly, and even take away the original water on the skin, making the skin drier. Therefore, moisturizing is not only to replenish water to the face, but more importantly, to repair the stratum corneum and make it healthy, so as to achieve the role of comprehensive defense.

According to the research, most seasonal skin problems are not real allergic reactions, but are caused by the weakening of the protective force of sebum membrane, which makes the skin unable to resist external stimuli. Coupled with the stimulation of the sun, wind and dust, these internal and external factors add up to make the skin sensitive. Moisturizing is the most important key in skin care. If you want to keep healthy, moist and transparent skin, you must replenish skin moisture at any time, so that the skin moisture content can be maintained at an ideal state of 15% to 2O%.

■ Damage caused by insufficient moisturizing:

When the skin is dry, it means that there may be problems with the health of the skin. Lack of moisture in the skin may lead to the following conditions.

1. Sensitive skin: 2. Acne acne: 3. Dull and rough: 4. Aging wrinkles.

■ How to replenish moisture to the skin?

Moisture is an indispensable element for the skin. Moisture-rich skin will be rich in skin, and the skin will look smooth, delicate and soft. Personal skin quality is mainly determined by the moisture content and sebum content of the stratum corneum. The stratum corneum on the skin surface usually contains about 20% water. The moisture is reduced, the skin is no longer delicate, and the whole looks dry and rough. When the moisture drops below 1O%, it is called dry skin. For dry skin, the tension and luster of the skin will disappear, and the keratin will easily peel off. The skin gives people a rough and dull feeling, and is prone to allergies, rashes and spots.

1. Now there are some spray-type springs on the market, which can replenish moisture and soothe and calm the skin when sprayed on the face or moistened with a mask. But after using the spring water, use a cotton pad to wipe off the excess water to avoid taking it away when evaporating.

2. Moisturizing masks and honey products can also give skin moisture and nutrition immediately, keeping skin delicate and smooth.

Moisturizing cream needs enough moisture to work. Proper use of humectant: A "humectant" is usually added to moisturizer as a water locking function, which can effectively absorb moisture and avoid skin moisture loss. Commonly used humectants include glycerol, urea and recently popular hyaluronic acid and collagen. However, the moisturizing agent itself has no moisturizing effect, and it needs to be supplemented with enough water to play its role.

3. Pay attention to the oil-water balance. Don't think that the skin is oily, so you don't need to do moisturizing work. Many people have the problem of oily skin. Oily skin will also appear dry and full of water, and skin cells will really be moist and full.

However, moisturizing is not just a matter of applying a lot of moisturizing lotion. Oily skin should use refreshing moisturizing products with less oil, such as emulsion, gel or emulsion. For dry skin with less oil secretion, you can choose thick cream-like skin care products to strengthen the moisturizing part. Using excessive moisturizing cream will exceed the load of the skin, but it will clog pores and produce acne or acne. Most people only pay attention to the problem of oil, ignoring the importance of hydration. Oily and dry skin leads to keratinization, pore blockage and acne. Although some people have acne on their faces, they will peel off. This phenomenon is that the moisturizing work is not done well. Skin with strong oil secretion needs to pay more attention to hydrating, keeping skin moist and pores unobstructed, so as to eliminate acne and oil smoothly.

4. In the air-conditioned artificial environment, the loss of water will be particularly obvious. Dry skin and lack of water will make keratin metabolism and sebum secretion chaotic, and hair follicles can not smoothly eliminate secretions and metabolized keratin, thus forming many closed acne and acne. Pay attention to moisturizing around the cheeks, usually around the face, such as forehead, hairline, sideburns and chin. Moisturizing can be concentrated not only in the center of the face, but also in the parts around the cheeks that are easy to dry.

■ How to choose moisturizing skin care products

Referring to the composition of human sebum membrane, the most important ingredients for moisturizing are water, humectant and oil. In order to keep enough moisture and oil in the skin, it is necessary to have a complete effect under the full action of humectant, oil and water.

Soft water, hot spring water, mineral water, deep sea water and other moisture. Oils and fats: sheep oil, olive oil, palm oil and other animal and vegetable oils, paraffin, vaseline and other mineral oils and fats. Moisturizer hyaluronic acid, ceramide, hyaluronic acid, glycerol, urea, etc.

■ Skin care products can be divided into lotion, emulsion, nourishing cream and moisturizing oil according to oil content. Toner only contains water and humectant, and moisturizing oil has the highest oil content. Be sure to choose the right type according to the skin type. The drier the skin, the more oily skin care products should be chosen.

■ The choice of skin care products is an attempt in itself, especially for people with sensitive skin, who are easily allergic or uncomfortable to skin care products. It is generally recommended to choose products that do not contain flavors, pigments and additives, and try less oily emulsions and creams to avoid increasing the burden on the skin. If you still feel that the oil is not enough, you can appropriately increase the oil content, such as moisturizing oil and vaseline.

■ The more expensive skin care products are, the more important it is to suit your skin. Try to achieve the maintenance effect with the least products and the simplest steps. Therefore, everyone should choose the appropriate skin care products according to the changes of skin quality.

■ Moisturizing methods for different skin types are as follows:

Dry skin: oily cream should be supplemented after skin moisturizing to maintain the function of sebum membrane and reduce water evaporation.

Sensitive skin: after moisturizing the skin with water, strengthen the use of moisturizing products containing moisturizing factors to repair damaged intercellular substance.

Neutral skin: Moisturize the skin with moisturizing lotion instead of oily cream to avoid clogging pores.

Oily skin: as long as you do a good job of cleaning, you can use lotion or moisturizing lotion in moderation. There is no need to use moisturizing emulsion unless it is particularly dry.

The skin is the largest organ of the body. To keep your skin in the best condition, you must have a healthy body. Balanced nutrition, adequate sleep, moderate exercise, stress regulation, emotional relaxation and regular life are necessary conditions for keeping skin young and beautiful. In addition to internal health, external maintenance is also very important. The principle of maintenance is to maintain the proper moisture and oil content of the skin, promote the metabolism of the stratum corneum and prevent the excessive production of melanin.

Maintenance methods include (1) correct cleaning and makeup removal (2) proper moisturizing and moisturizing (3) avoiding ultraviolet radiation.

◆ Skin care steps:

Most people always think that the so-called maintenance is to choose some skin care products with high nutritional content to nourish the skin. Actually, this is putting the cart before the horse. Skin care should start with the most basic steps, and then choose supplementary care products according to the degree of skin demand. The basic maintenance steps are: cleaning, moisturizing and sun protection. That is, the basic elements that the skin needs most: cleaning dirt, providing necessary moisture and nutrition for the epidermis, and protecting the skin from ultraviolet rays.

Cleanliness-remove dirt, aged keratin, excess grease and cosmetics.

☆ Wash your face clean-in short, wash your face. People with neutral skin only need to wash their faces with clean water and general cleaning supplies; People with dry skin should use facial products with good moisture retention or weak acidity; As for oily skin, it is advisable to wash your face several times a day and carefully choose a mild and non-irritating facial cleanser; Because oily skin emphasizes cleanliness.

The specific method is:

1. Wash your hands first, put appropriate facial cleanser on your palm, add a little water, and rub it into foam by hand.

2. From the cheeks, gently rub the facial cleanser, then clean the T-shaped part from the forehead and carefully clean both sides of the nose.

3. Rinse facial foam with warm water. Hairline, chin and behind the ears are easily overlooked. You can wear a hair band and look in the mirror at any time to confirm.

4. Finally, gently wrap your face with a clean towel and pat it to remove moisture. Avoid excessive friction.

Wash your face correctly,

You should avoid facial sebum membrane damage, making the skin drier and unprotected. Some skin care products manufacturers emphasize thorough cleaning and then use skin care products to build a protective film for the skin, which is actually overkill. In fact, the natural protective film components of the skin are irreplaceable by any skin care products. The best way is to reduce the frequency of washing your face and use mild alkali-free and soap-free cleaning products. However, the frequency of washing your face every day is different for all skin types. For dry skin, the frequency of facial cleanser can be maintained once, for mixed skin, once or twice, for oily skin, no more than three times. For people with sensitive skin, excessive washing will accelerate the loss of moisturizing factors. When the skin can not successfully repair the sebum membrane components, the skin is more prone to allergic injuries due to dryness.

Moisturizing-provide nutrients and oil for the skin and strengthen moisturizing.

☆ Why should the cream moisturize? Because lack of water can make the skin feel rough and uncomfortable, when the face feels dry and tight, it is also a sign of skin lack of water. If you don't replenish water at any time, wrinkles will come long ago! Long-lasting moisturizing can maintain the ideal moisture of the skin. At present, there are many daily necessities for moisturizing, but the products with high prices may not have the best effect, so it is better to choose the ones suitable for personal skin. In addition to external moisturizing work, remember to drink plenty of water to replenish the lost water inside! For people with oily skin, you should avoid using moisturizing products or products with high oil content, otherwise it will easily lead to pore blockage and acne.

1. Pour the beauty liquid or emulsion into the palm of your hand and heat it with body temperature to improve the permeability.

2. After using the lotion, just apply the lotion to the place where the skin feels dry and tight, and spread it from the inside out.

3. After application, you can wrap your face with your palm, which can promote the penetration of nutrients.

4. At the same time, don't neglect the maintenance of the neck, put your face up and apply lotion from bottom to top.

Sun protection-sunlight is the killer of tender skin, which can lead to dark spots and wrinkles.

☆ Sun protection is the key step of skin care, and sunlight is the main cause of skin aging, dark spots and wrinkles. Long-term sunlight will destroy the elastic fibers and collagen fibers in the dermis, making the skin lose its elasticity and tension unconsciously and produce wrinkles in advance. UVA in ultraviolet rays has strong penetrating power and can penetrate through thick clouds and glass, which is the main cause of photoaging wrinkles. UVB in ultraviolet rays is the main factor that causes and aggravates skin spots. No matter what the weather is, try to avoid outdoor activities between 10 and 2 pm. br/>； Specifically: 1. Get into the habit of sunscreen and apply sunscreen half an hour before going out, rain or shine. 2. Both sides of the cheekbones, the bridge of the nose and the ears are all areas with high ultraviolet radiation. Sun protection must be strengthened and can't be missed. 3. Be sure to choose a sunscreen product that can protect both UVA and UVB. If chemical sunscreen needs to be replenished at any time, apply it every few hours according to the sun protection factor.

◆ Relationship between age and skin care

Generally speaking, young women secrete more oil, and the focus of skin care should be cleaning and degreasing. In order to reduce unnecessary irritation to the skin, try to reduce heavy makeup. Of course, sun protection is also essential to prevent skin aging and pigmentation. Middle-aged female friends, due to the decline of skin moisturizing ability, should give priority to moisturizing and anti-wrinkle, in order to reduce skin allergies, should avoid excessive skin care. We can't ignore the importance of sun protection. At the same time, we should also pay attention to the laws of life.

◆ Five factors affecting the secretion of sebaceous glands:

1. Genetic factors: This is the most important factor, which determines more than half of sebum secretion. The amount of sebum on the face is 4 ~ 10 times that of other parts, and the sebaceous glands in the T-shaped part are as high as 700~900 per square centimeter. Such as the nose, eyebrows, hairline, behind the ear, scalp, chest and so on. These are the developed parts of sebaceous glands.

2. Endocrine and psychological stress: Androgen can promote the hyperplasia and hypertrophy of sebaceous glands and increase secretion, so the skin has obvious oily phenomenon after puberty. Sebaceous gland secretion is dominated by nervous system and endocrine. Some people are particularly prone to oil, acne and even hair loss when they are nervous and overworked. This may be directly through the sympathetic nerve, or it may be because emotions affect abnormal hormone secretion.

3. Dietary drugs: Both sugar and fat will increase the production of oil in the body, so eat more foods with high fiber and low fat. Meanwhile, vitamins B2, B6 and E are all important vitamins in sebum metabolism. Drugs with androgen activity, such as steroids, can also make sebaceous glands secrete a lot of oil.

4. Temperature and humidity: The oil secretion will increase by 10% every time the temperature rises by one degree. When the temperature is high in summer, sebaceous glands will secrete more vigorously, resulting in serious oil production. When the surface oil increases, the proportion of water decreases, and the dryness of skin will promote the further secretion of sebum, which makes the problem of external oil drying inside more serious.

5. Microbes and immune factors: There are many acne bacilli, Staphylococcus albus, blastomyces folliculorum, dandruff and hair follicle worms in normal hair follicle sebaceous glands. Excessive growth of microorganisms in hair follicles will produce free fatty acids to stimulate sebaceous glands to produce oil and cause inflammation. In the period of illness, stress and decreased immunity, sebum secretion disorder often occurs.

◆ The key to regulating sebaceous gland secretion

1. Clean correctly

When many people feel greasy on their faces, their first reaction is to wash their faces. In fact, excessive washing, degreasing and exfoliation may cause skin damage, and it is easy to stimulate the continuous secretion of oil. Only by choosing the right cleaning products and washing your face correctly is the best way to save fuel. When cleaning, it is recommended to wash your face with cold water and mild facial cleanser. The frequency of washing your face depends on the oily degree of your skin. For oily skin, you can wash your face up to four times a day (morning, noon, evening and before going to bed). You should choose products with strong oil removal ability. If you belong to mixed sensitive skin, avoid excessive cleaning and hot and cold stimulation, and don't wipe your face with a towel.

Moisturizing and calming

Dry skin is caused by imbalance of moisture and sebum. Too dry skin will stimulate sebaceous gland secretion in a feedback way, but it will produce a dry and greasy feeling. Therefore, providing sufficient moisture to the skin, doing a good job of moisturizing at any time, maintaining oil-water balance, also has the effect of relieving sebum secretion.

In recent years, refreshing moisturizing spray products have become popular. This moisturizing spray is easy to carry and use, and it can replenish water at any time as long as it is sprayed. In addition to moisturizing, most of these products also contain soothing and calming ingredients, which can also promote the normalization of blood circulation, regulate skin temperature and slow down redness and fever caused by hot climate.

3. Anti-inflammatory and bacteriostatic

Inflammation and damaged skin will cause rapid water loss, and some inflammatory substances will also acidify and denature sebum, aggravating the symptoms of itching and redness of skin. In addition, some microorganisms depend on the oil component of the skin to survive. If microorganisms multiply in large numbers, it will destroy the sebum structure and release a large number of irritating free fatty acids, and the skin condition will deteriorate obviously. Anti-inflammatory and bacteriostasis is an important key to fight seborrheic dermatitis, and it can also improve the degree of acne attack.

4. Oil removal, oil control and oil balance

Because sebum secretion is the natural metabolism and protection function of human body, even the best oil control products can only double the oil delivery time at most. For example, people who get oily two hours after washing their faces can use oil control products, and the time for facial oiling can be extended to four hours. It is almost impossible to find a product that completely inhibits oil production, so different from the traditional concept of inhibiting oil production, oil-water balance is a widely accepted maintenance method at present, and the products for conditioning oil also adopt multi-component compound formula.

Exfoliate and shrink pores

The more oily the skin, the more obvious the phenomenon of stratum corneum hyperplasia. Overkeratinized epidermis is not easy to be discharged from hair follicles, and it is also easy to cause large pores and blockage, leading to acne and acne. Proper exfoliation and deep cleaning can help to exfoliate old horniness, refine skin and smooth pores. However, while removing the old waste cutin, we must pay attention to the frequency of exfoliation and the intensity of cleaning, so as not to cause excessive irritation to the skin.

Although exfoliation can smooth the skin and smooth pores, it will also weaken the normal protective layer of the skin, so it is necessary to strengthen moisturizing and sun protection after exfoliation treatment. Once the skin itches and stings, it means that the epidermis has been injured and can no longer be forced to do it.

Appropriate skin care products can achieve the expected results. Modern people's skin problems are often caused by wrong skin care methods and insufficient understanding of skin.

Generally speaking, skin types can be divided into five types: oily, neutral, dry, mixed and sensitive.

■ Neutral skin care focus:

Normal secretion of oil and sweat on neutral skin makes the skin delicate, delicate and elastic.

◆ The skin tissue is compact, the texture is delicate, and it is not dry or sticky. ◆ It has natural luster and ruddy feeling and belongs to healthy skin. Strong resistance, not easy to produce skin changes.

1. Maintain proper maintenance, pay attention to sun protection during the day, and remove aged keratin regularly.

2. The skin changes easily with the seasons. Oil in spring and summer, dry in autumn and winter. Be sure to carefully observe the changes of skin quality and take appropriate maintenance measures.

3. Basic maintenance, cleaning the skin, keeping the skin stable and maintaining the water-oil balance of the skin.

4. Pay attention to the usual diet and living habits, and keep a happy mood. Prevent wrinkles from appearing prematurely.

Strengthen the maintenance of sunscreen → sunscreen products; Skin activation → vitamin C, fruit acid

■ oily skin care focus:

Oily skin The surface of the skin is rough and greasy, and the function of sebaceous glands is too exuberant.

◆ Thick and hard skin, rough texture, thick pores and opacity. ◆ Pores are easily blocked, forming lesions such as acne, whelk and pimple. ◆ Easy to apply makeup and remove makeup.

1. It is easily influenced by living habits and physiological factors. Stress, improper eating, lack of sleep, staying up late, emotional instability or female menstrual period can all cause sebaceous gland secretion disorder.

2. The focus is on skin cleansing. It is best to wash your face with facial cleanser, 2-3 times a day; When choosing skin care products, you should choose skin care products with high water solubility, replenish skin moisture as much as possible, and don't use cream with too much oil, otherwise it will cause hair follicle blockage.

3. In addition to cleaning, it is also necessary to relieve the secretion of sebaceous glands and adjust the pH value of the balanced epidermis. It is also important to exfoliate and change skin regularly, and it is also important to converge pores, which can not only remove oil, but also inhibit oil.

Strengthen maintenance and cleaning → facial cleanser, deep mask and bactericide;

Exfoliation → fruit acid, salicylic acid, scrub;

Convergence → oil control products, convergent water and oil-absorbing facial tissues.

■ Focus on dry skin care:

Dry skin lacks oil and water secretion, and loses its softness when it is dry.

◆ Thin skin, dull color and lack of luster. After washing your face, your skin will feel tight and tingling. ◆ The skin is dry, sensitive and inflamed, tight and inelastic, easy to age, and produces fine lines and dark spots. ◆ Keratin feels rough and dry. It is easy to grow scales and peel off, and it is easy to float powder on makeup.

1. Avoid excessive cleaning, pay attention to skin care, and strengthen moisturizing and hydrating.

2. Choose nutritious skin care products to supplement skin oil.

3. Moderate massage or facial care can increase skin vitality, promote metabolism and avoid aging.

4. Avoid ultraviolet radiation, strengthen protection and whitening, and be sure to protect yourself from the sun during the day to avoid dark spots and fine lines.

Strengthen maintenance and moisturizing → nourishing cream, beauty lotion, anti-wrinkle → tretinoin, L- vitamin C and fruit acid.

Sunscreen and freckle removal → sunscreen products and whitening agents

■ Key points of mixed skin care:

The skin surface of mixed skin has parts that are easy to get oily and dry.

◆ Due to environmental and physiological factors, sebum secretion is unbalanced, and more than two skin types are mixed on the same face. It belongs to unstable skin and is a common skin type of modern people. ◆ T-shaped parts have obvious pores, exuberant sebum secretion, and are prone to acne, acne and acne. Lack of oil and water around cheeks, lips and eyes, resulting in fine lines due to dryness.

1. Take different nursing methods according to the characteristics of skin parts. Pay special attention to the changes of seasons and the temperature difference between morning and evening. It is easy to get greasy in spring and summer, so keep your skin fresh and astringent. In autumn and winter, more is to strengthen moisturizing and moisturizing.

2. Check skin changes at any time, use appropriate skin care products in different parts, and adjust the oil-water balance.

3. Adjust the regularity of living habits and pay attention to diet, sleep and mood. And overcome the internal and external factors that affect the skin.

Strengthen the maintenance and refreshing maintenance → Use the refreshing maintenance method of oily skin on the whole face to strengthen the moisturizing of dry parts of the cheeks.

Moisturizing maintenance → Moisturizing maintenance of the whole face of dry skin, avoiding oily parts.

■ Pay attention to sensitive skin care:

Sensitive skin is thin, often redness, rash, itching, and obvious microvessels.

◆ It does not belong to a specific skin type, and the skin is sensitive and fragile, which is closely related to the congenital constitution. ◆ The skin lacks luster, the cheeks are prone to congestion and redness, and the capillaries clearly emerge. ◆ The epidermis is fragile, and it is easy to cause eczema, sensitivity, redness and itching when slightly stimulated.

1. Prevent sensitive reasons. Avoid any skin care products that are irritating, too greasy and have high fragrance.

2. When trying to maintain new cosmetics, first rub it on the inside of your arm and do an allergic reaction test.

3. Environmental temperature, humidity and seasonal changes should be properly protected to avoid ultraviolet radiation.

4. Use less seasonings in the diet to avoid irritating food.

Key points of skin care in spring

1. Choose refreshing and moisturizing skin care products: Spring is the season of active human functions, and sebaceous glands begin to secrete vigorously. At this time, the skin is actually not short of oil, and feeling dry is caused by water shortage and oil-water imbalance. In spring, you should choose skin care products with refreshing and moisturizing effects, such as make-up water and moisturizing lotion. And avoid creams containing a lot of oily ingredients. When using special products for sensitive skin, they need to be replaced one by one: if the skin is fragile and sensitive on weekdays and the seasons change, it is easy to feel uncomfortable or sensitive if you want to "change seasons" skin care products once. During this period, skin problems caused by humidity and temperature changes emerge one after another, so it is suggested to temporarily switch to special products for sensitive skin. The replacement of skin care products must also be updated one by one. New skin care products can be used one by one at intervals of one to two weeks. Otherwise, the skin is easily allergic due to the inadaptability to a large number of new products. If allergic conditions occur, it is difficult to judge which bottle is out of order.

2. Avoid using irritating drugs and skin care products: People with sensitive skin in spring should pay more attention to the ingredients of functional skin care products. For example, people who are keen on skin rejuvenation and whitening use fruit acid and A acid. , we must consider the skin's endurance. If overused, it will easily reduce the skin barrier function and make the skin fragile and thin. When the environment changes, the skin is prone to various sensitive symptoms such as redness and itching. Using functional products in spring can help the aging skin to renew quickly. However, skin without keratin protection is vulnerable to strong winds and sunlight. Therefore, some skin allergies in spring are also related to maintenance and irritation or allergies caused by drugs.

Main points of skin care in midsummer ※

Due to the hot weather in summer, the secretion of sweat glands and sebaceous glands also increases, discharging a lot of sweat and waste, helping the human body to emit excess heat. If you don't pay attention to cleaning the skin, it will make the waste left on the skin accumulate, cause pore blockage, cause hair follicle inflammation, and easily lead to acne and acne. Therefore, you should take more baths in summer, clean your skin, keep your pores open and reduce the chance of getting sick. In addition, people with exuberant sebum secretion should abstain from greasy, spicy and irritating foods and eat more light foods.

Because the human body sweats too much in summer, the metabolic system is easy to lose balance, so in autumn, local skin will dry and peel due to insufficient water, which usually happens around the lips and under the nose. Therefore, it is necessary to increase skin hydration care in summer and autumn. When nursing at home, you can use products such as hydrating essence and hydrating gel. These treatments can be done every night. This can increase the moisture and elasticity of sebum and strengthen the skin's resistance. At the same time, it is necessary to drink more water, maintain normal metabolism in the body, and balance inside and outside, so as to achieve good results. You should drink more fruits and vegetables rich in vitamins in your diet, such as lemon, citrus, watermelon, strawberry, carrot and tomato. Help the skin restore metabolic balance.

"Golden Lady" beauty products, after a period of beauty, the skin will become delicate and fair. Pearl powder and herbs are also good.

But it is not good to use too many whitening products. Generally, whitening products contain a lot of lead and mercury, which is very harmful to the skin. Skin is easily dependent on these whitening products, and long-term use will produce spots, and the consequences are terrible!

So please have a look.

The secret of star whitening: tasting whitening food.

Don't think that as long as you do enough "face" kung fu, you can regain a fair face. Beauty is always from the inside out, and diet is also an indispensable part of the whitening chain. Vitamin C, protein, minerals and vitamin A are all high-quality nutrition sources for whitening skin. Therefore, when eating fruits and vegetables containing these ingredients, it is best to give priority to raw food. If you can't eat it raw, cook soup. In addition, foods rich in vitamin A can be cooked with oil, which is more conducive to absorption.

Lemon: Lemon is rich in vitamin C, which is regarded as an important ingredient in making whitening skin care products by the beauty industry. Especially in the whitening skin care products launched in summer, lemon is an indispensable protagonist, which shows that it is really unique in whitening skin. Lemon is not only rich in vitamin C, but also contains vitamins A, B 1, B2 and PP, which not only has whitening effect, but also can dilute melanin formed in the skin. PP component has strong astringent and antibacterial effects. Drinking a glass of lemonade in the morning can not only expel toxic substances from the body, but also have a natural whitening effect, which helps to eliminate facial freckles.

Vinegar: Add 250g soybean to vinegar, soak it for 15 days, and eat 10 capsules a day to dilute skin melanin.

Yogurt: Yogurt contains a variety of vitamins, among which vitamin C can reduce the production of melanin and keep the skin fair.

Tremella: It can not only whiten the skin, but also help to excrete toxins from the body. It's okay to eat more.

Stars are not only fashion leaders, but also experts in skin care. Listen to how they deal with their own skin whitening problems. Does it inspire you?

Maggie Cheung

Although the skin is naturally fair, even the best skin should be cared for.

"Generally don't go to the beauty salon, skin care just do it yourself. I like to use fruits for skin care, such as lemon, which can make my skin clean and fair. If you add some herbal juice to the mask made of fruit, honey and egg white, the whitening effect will be better! "

No matter what type of skin, you need to replenish moisture before whitening.

"In spring and summer, I like to use the Borghese Sea Mud Mask, which can not only replenish skin moisture, but also relieve pigmentation after sun exposure, making skin white and transparent."

Zhou Xun

Whitening must not be sloppy!

To maintain fair skin, you should do a good job of sun protection all year round. "It's not just midsummer. After a day in the sun at home, I will apply ice to my face, calm down and moisten it at once. At the same time, I think makeup removal is more important than makeup, which is also a good way to make the skin clean and transparent. "

Helen Tao

Vitamin c and vitamin e are
