Basic knowledge of beauty and skin care
Basic maintenance skills:
1. Eat more foods with antioxidant effects, such as vitamins C and E, green tea polyphenols and grape polyphenols. , all have antioxidant effect, you can eat more fruits; Because grape polyphenols exist in grape seeds, it is suggested that when eating grapes, you can drink grape juice instead and juice with grape seeds to effectively absorb grape polyphenols.
2. Reduce the formation of peroxide
Peroxide is the main cause of free radicals. If it can be avoided as much as possible, it can effectively prevent cell oxidation. If you smoke less and eat less fried food, you can effectively avoid the formation of peroxide in your body.
3. Pay attention to moisturizing at any time
Intake 2000ml of water every day, and carry moisturizing products at any time to replenish them in time to avoid dry and fine lines on the skin. Moisturizing tip: You can use paper film to soak lotion and make a five-minute moisturizing mask.
Moderate exfoliation
Exfoliate moderately according to your skin condition. Exfoliation does not have to be exfoliated, but it can be targeted at the local area. The simple way to judge when and where to exfoliate is as follows-when facial skin becomes rough, pores become obvious and acne appears, it is a sign of exfoliation.
2. Basic knowledge of beauty
Basic knowledge of skin beauty 1. Skin structure The skin is divided into three layers from top to bottom, namely epidermis, dermis and subcutaneous tissue.
? (1) Epidermal layer 1, stratum corneum The stratum corneum is the outermost layer of the epidermis and an important barrier to the epidermis. With the normal metabolism of the skin, the stratum corneum cells will eventually die of old age and fall off.
However, with the continuous growth of age, the metabolic capacity of the human body slows down. Therefore, dead cells will continue to accumulate, leading to rough, dull and even peeling skin.
At this time, it is necessary to use anti-free radical skin care products to help the skin present a delicate and smooth state and prevent premature aging of the skin. 2. Basal layer The basal layer is the lowest layer of epidermis. In this layer, there are two kinds of cells, one of which is basal cell. Basal cells have a very strong proliferative ability and will continue to divide, from one cell to two, and then from two to four. When there are more and more basal cells, they will start to grow up and form spinous cell layer, granular layer, transparent layer and stratum corneum.
Then it falls off naturally, which takes 28 days. Healthy skin should have good cell regeneration function, but everyone's function will decline with age. At this time, skin care products are needed to help the skin.
The protective effect of melanin on skin and the production of pigmentation are sparsely dispersed in basal cells, namely melanocytes. The color of normal skin is related to the content of melanocytes, which can prevent ultraviolet rays from penetrating the skin and damaging deep tissues.
After sun exposure, the skin turns black because melanin increases, thus strengthening the skin's resistance to sunlight. However, after melanin is produced, due to poor metabolism and poor maintenance, it is easy to produce pigment precipitation and form pigmentation.
So we need sunscreen products and whitening products to help melanin metabolism and prevent pigmentation. (2) There is a reticular layer structure in the dermis, which consists of collagen fibers and elastic fibers. The structure is loose and staggered to form a network structure.
This reticular structure supports the skin and makes it have good compactness and elasticity. As time goes on, fibers become brittle. Once broken, a part of this network structure will collapse, causing skin wrinkles.
This situation cannot be recovered by skin care products, so when recommending such products to customers, don't exaggerate their efficacy, so as not to become dishonest sales. As for some fine lines on the skin, we call them expression lines, which belong to false wrinkles and are caused by the following factors: lack of water, lack of fat and accumulation of dead cells.

Whitening mask is different from moisturizing mask. Vitamin C, amino acids and citric acid in whitening mask are unstable components, which will be ineffective after heating.
The components of clean, compact and cell-activated mask are relatively stable, but they can promote absorption after heating. Skin care tips If the skin is short of water [hunger] [hunger], oil secretion will be more vigorous, and oily skin is particularly easy to absorb dust. When dust accumulates in pores for a long time, it will form large pores. Contact between oil and air will cause inflammation of hair follicles, leading to acne, and the skin will look particularly dull and oily, and the pores will become particularly large and unsightly! So the first step of skin care is to clean the skin. 1. Skin care tips A bag of milk a day can whiten and help sleep before going to bed; 2. Eat more soy products to make your skin tender; 3.

4. Who can introduce some beauty knowledge?
A comprehensive introduction to skin care and beauty knowledge * Skin * Skin * Foundation * Care * Management * Articles * If you want to take good care of your skin, you must first understand our own skin and know what you know to win every battle! Sand tells you the basic knowledge of beauty care: you should know that skin is actually like a film or barrier, which can protect your body from harmful external factors.
Because nerve tissue is sensitive, we can feel the changes of the external environment through the sensory function of nerve. Skin is made up of many different cell groups.
So let's first understand the structure of the skin. Maybe these are all theoretical, but if you can know the basic structure of skin in advance, it will be very helpful to learn how to maintain skin! 1) Structure of skin A. The skin is divided into three layers: epidermis, dermis and subcutaneous tissue.
The total thickness of the three layers is 1.25mm, and each layer plays an important role in maintaining skin health. B, subcutaneous tissue is a layer of fat, which can protect the upper cells, provide buffer and prevent external shocks.
C, the dermis is located in the central layer of the skin, and contains collagen: a protein needed by the human body, which can make the skin elastic and increase its flexibility and adaptability. In addition, the dermis also contains tiny blood vessels, nerves, hair follicle tissues, sweat glands and sebaceous glands.
D, epidermis is located in the top layer of skin. The thickness is 0. 1mm, and its main function is to renew cells and their metabolism.
The growth of skin is a long process. However, the newborn cells derived from epidermis gradually floated up, lost water and flattened.
When the thickness of these flat epidermal cells accumulates to about 20 layers, the so-called stratum corneum will be formed. This thin red surface is very important to the human body! It can prevent the skin from losing moisture, avoid being hurt by environmental factors, and protect cells and organs inside the human body.
The oil and juice it secretes cover the surface, forming another natural protective film. Usually we do all kinds of care and maintenance work on this skin, such as supplementing water and nutrition.
Cells on the skin surface will continue to fall off and be replaced by new cells. The time required for skin metabolism will change with age.
Young skin takes about 2 to 3 weeks, but mature skin takes about twice as long. The longer the metabolic time, the easier it is to lose water.
Therefore, we usually make facial masks, exfoliate and eat fruits and vegetables, which all help us to speed up the metabolism in the body. 2) The epidermis of subcutaneous tissue (1): Like the coat of skin, it has five layers, which is most closely related to cosmetics; Has metabolic and protective effects.
In the epidermis, there are: stratum corneum: it contains 20 to 30 layers of flat and dead cells. Interstitial tissues are connected together to form a barrier; Transparent layer: exists in the palm and sole of the foot; Granular layer: also called gel layer, there are countless reflective particles between cells; Spiny layer: the thickest layer of epidermis, where lymph flows between cells and provides nutrition for epidermal cells; Basal layer: composed of columnar basal cells and dendritic myna leukocytes.
(2) Accessory organs of the skin: sebaceous glands: sebaceous glands attach to the hair and secrete fatty substances and sebum, which plays an important role in forming a protective film on the skin surface! The amount of sebum secretion determines the muscle quality of the skin. Sweat gland: It can be divided into eccrine sweat gland and apocrine sweat gland to secrete sweat.
Eccrine glands can secrete about 900CC of sweat almost a day, 99% of which is water and has no other odor; Apocrine glands are secreted from pores when sweating and have a special smell. Sebum film: It is an acidic film formed by evaporated sebum, sweat and water, half of which is water and half is oil. It exists on the skin surface and can protect the skin from external environment.
Therefore, sand should remind everyone not to wash their faces excessively, let alone wash their faces with soap. (3) Physiological functions of the skin: The skin is a living organ on the body surface, which has many functions and has a great influence on the beauty of the skin! Its function is as follows: performance: the physiological condition inside the body is reflected on the skin.
Such as acne and spots. Perception function: the skin responds to touch, cold, temperature, pressure and pain through the endings of sensory nerves.
Thermoregulation: the skin has the function of keeping a certain temperature when the temperature changes! Respiratory function: lung breathes more and skin breathes less. So in the current skin care products, it is very good to help the skin breathe.
For example, the negative ion liquid contained in desire is the best proof of today's "skin breathing" theory, which helps the skin to breathe spontaneously. Moisturizing effect: Sebum membrane prevents water evaporation.
Nutrition: capillaries provide nutrition for epidermis. Regeneration: the process of cell division.
These effects have a great impact on the health and beauty of the skin! I hope everyone can read more about this knowledge and help them better understand the skin. Blistering skin and skin with black spots and freckles 1) Blistering skin Its scientific name is acne vulgaris.
In fact, it is what we call acne. About 60% to 90% of adolescent men and women have experienced acne, so it's called this! Skin characteristics: large pores; Keratin is thick and rough; There is more sebum secretion in t-type site; It is easy to grow blackheads and acne. The formation process and types of blisters: how to say, there are internal and external causes! Normal skin has smooth pores and normal sebum secretion.
On the other hand, the facial bullous skin has excessive keratin hypertrophy and sebum secretion, which causes keratinization of the hair follicle wall. Keratinocytes block pores, and yellow and white pimples can be seen from the outside. These are all white-headed acne.
The front end of sebum block is exposed to the skin surface, and it is blackhead acne that is oxidized by air! Inflammation, swelling and pain caused by bacterial infection are papular. Papular facial blisters will continue to deteriorate, pustular type will fester due to bacterial reproduction, and it is easy to leave scars after healing.
Cause: (1) External cause: such as exuberant sebum secretion! Incomplete cleaning, dirty hair, improper use of cosmetics, etc! (2) Internal cause: viscera function.
