What are the consequences of serious damage to sebum membrane? Many ingredients of skin care are exposed in daily life, and the skin care effects brought by different ingredients are also different. What are the consequences of serious damage to the sebum membrane below?
What will happen if the sebum membrane is seriously damaged? 1 sebum membrane is a thin film covering the face, which consists of sebum secreted by sebaceous glands, lipids decomposed by keratinocytes and sweat emulsified by sweat glands.
Its main components are ceramide, squalene (alkane), linoleic acid, linolenic acid and lipid.
The main function of sebum film is to lubricate skin, keep moisture, inhibit microorganisms, block ultraviolet rays and have anti-inflammatory effect;
The damage of sebum membrane will lead to the damage of skin barrier function, so girls, don't over-clean your skin when washing your face.
Excessive cleaning or rubbing of skin will lead to the damage of sebum membrane, which will make the cuticle of skin thinner and the intercellular substance in skin cells decrease.
Under what circumstances will the lipid membrane be damaged?
The damage of sebum membrane will damage the barrier function of our skin, just like the broken tiles in our house, which will affect the environment at home at ordinary times.
There are many reasons for skin sebum membrane damage. For example, if we wash our face too much, our sebum membrane will be damaged. Therefore, in the process of daily face washing, we usually wet the towel with clear water or warm water to properly clean the face.
When washing your face, rubbing the skin with your palm too hard will also damage the sebum membrane and make the stratum corneum thinner. Be gentle with yourself and your skin will be better for you.
Similarly, under the conditions of sun exposure, anoxic environment, cold and nervous mood, the sebum membrane of the skin will also be damaged. When you go out in summer, you should do a good job of sun protection, keep warm in winter, keep a good mood at ordinary times, and do more aerobic exercise when you have time. Sweating is not only good for your health, but also good for your skin.
In life, you will find that people who are optimistic and exercise regularly maintain their skin relatively well.
Key points: Fruit acid therapy, laser therapy and the use of cosmetics containing hormones and heavy metals can also cause sebum membrane damage;
Attention, girls who love beauty should be careful in choosing cosmetics, and pay attention to protecting themselves while loving beauty. Fruit acid therapy and laser therapy will directly lead to the destruction of our skin barrier function, which is equivalent to walking barefoot. If the later repair work is not done in place, it will lead to skin inflammation, pigmentation or pigmentation.
Do not use cosmetics containing hormones or heavy metals for whitening. Long-term use of cosmetics containing hormones will make the skin dependent on hormones, and improper handling may lead to hormone face;
Among the heavy metals, hydroquinone is the first to bear the brunt, which has been listed as a banned product in cosmetics by the state. Hydroquinone can interfere with the production of melanin, thus achieving whitening effect, but due to its irritation, it will cause irritating dermatitis and pigmentation.
The use of "whitening" heavy metals such as lead, mercury and arsenic will lead to multi-colored spots on the skin. Lead and mercury will not only remain on the face, but also damage the liver, kidneys and nervous system.
Internal chain reaction caused by lipid membrane injury
First of all, the skin's ability to lock water decreases.
The sebum membrane is damaged and the stratum corneum becomes thinner, which leads to the increase of water loss of cells through the skin epidermis, and the lack of water in the skin leads to insufficient nutrition transportation and supply;
At this time, the skin's immune system begins to work, promoting the contraction frequency of the heart and the increase of blood circulation. Increased blood circulation will lead to telangiectasia, mild symptoms will lead to red blood, and severe symptoms will lead to tissue edema, itchy skin and redness.
Increased blood circulation may also lead to skin allergies, and the skin immune system will release histamine, resulting in edema, itching and redness of tissues.
When the skin is red, swollen and itchy, it shows that the anti-inflammatory effect of sebum membrane has failed, and the skin will have an inflammatory reaction. If the skin barrier is not repaired when skin inflammation occurs, pigmentation or pigmentation will appear in the later stage.
Second, the skin's ability to resist external stimuli declines.
When our skin barrier function is destroyed, it is equivalent to a mobile phone without a film, or a person streaking without clothes, or going out without a mask, which is quite dangerous. A little stimulation can lead to skin allergies;
After skin allergy, the immune system in the body will start to operate, releasing histamine, resulting in edema, itching and redness of skin tissue.
Especially cosmetics containing hormones or heavy metals. When the sebum membrane is destroyed, continue to use cosmetics. Stimulation of hormones and heavy metals will aggravate skin sensitivity, leading to inflammatory reaction, pigmentation and other symptoms.
Third, the sun resistance is declining.
After the sebum membrane is damaged, the skin's ability to resist sunlight is reduced, and the stimulation of sunlight and ultraviolet rays on the skin will lead to active melanin, and then pigmentation or pigmentation will occur.
How to repair skin barrier function
For a series of symptoms caused by the destruction of skin barrier, we must first do a good job of repairing. The sebum membrane is destroyed, the stratum corneum becomes thinner, and the skin cells lose more water, resulting in dryness, itching and redness of the skin. The most essential thing is to lose water.
Then when we are doing skin repair, the first step is to hydrate and moisturize the skin to keep it moist;
Ceramide is the main component of intercellular lipid in stratum corneum.
Squalene: can rebuild sebum membrane and lock water;
Step 2: promote skin regeneration and complete epithelization;
Use skin care products containing collagen, growth factors and other ingredients to quickly repair and regenerate damaged skin.
Step 3: use reasonable drugs to inhibit pigmentation, and try to reduce the occurrence of inflammatory pigmentation by blocking the path of pigmentation and sun protection; (such as using skin care products containing levorotatory VC, etc. )
The following is the logical sequence of using maintenance products:
The first step: stimulate skin growth, give basic nutrition and provide a humid environment;
Step 2: repair the stratum corneum and give intercellular lipid; '
Step 3: lock water and moisturize, and the oil covers the skin surface to play a sealing role and prevent water loss;
Step 4: isolate the sun;
Step 5: Whitening.
Principles of repairing allergic skin:
1. Use repair products with simple ingredients to reduce the allergic rate of products;
Avoid the use of "traditional Chinese medicine mask" (because of its complex composition), and choose a dressing of mechanical size, which is mainly composed of collagen, repair factor and hyaluronic acid.
2. The product components are aimed at the target organization;
Basic fibroblast growth factor (bFGF[2]) is used for dermal injury, KGF[3] (keratinocyte growth factor) and EGF[4] (epidermal growth factor) are used for epidermal problems, ceramide can be used for repairing ordinary tender skin without damage, and products containing squalene are used for outer packaging.
3. Reasonably control the dosage of repair products;
After the skin is damaged, it is necessary to control the dosage of repair products, which is at most 3-4 times of the daily dosage, otherwise it may cause skin allergy due to the heavy burden of drug metabolism and absorption.
Repair order of allergic skin:
1, first use cosmetics containing collagen, hyaluronic acid, squalene and jojoba oil;
Within 2.24 hours, if there is no discomfort such as itching, redness and swelling, then use products containing growth factors; If the dermis is damaged, bFGF-based growth factors are used.
3. Under the condition that the epidermis is basically complete and scabbed completely, the repair product containing ceramide and other components is used again;
4. Some irritating whitening products (acid VC). Don't use it too early.
What are the consequences of serious damage to sebum membrane? 2 What problems will occur after the sebum membrane is damaged?
After the sebum membrane is damaged, the most obvious thing is that the skin becomes dry, itchy and desquamate due to the obvious increase of transdermal water loss, and the skin becomes particularly sensitive and irritable. Slightly cold or hot, or using some cosmetics, causing allergic symptoms such as erythema, papules, desquamation and itching.
The damage of sebum membrane may be related to the excessive use of some cleaning products, masks or cosmetics and products with special effects of acne and freckle removal. In these products. There are also some exfoliating agents that can exfoliate, and the sebum membrane will be damaged after a long time.
Symptoms of sebum membrane damage
Sebum membrane refers to the sebum secreted by sebaceous glands, which is emulsified with sweat and a small amount of inactive cells falling off the skin surface, which has a certain protective effect on the skin. The damage of sebum membrane generally shows the symptoms of dry skin and peeling, and the skin becomes more sensitive, which can also cause symptoms such as red blood and itching.
1. Dry peeling: The sebum membrane is located at the top of the stratum corneum, and the moisture in the sebum membrane can keep the skin moist and prevent chapped skin. If the sebum membrane is damaged, the skin will lose its protection and cannot keep the skin moist, resulting in imbalance of water and oil, accompanied by symptoms such as dry skin and peeling;
2, sensitivity: damage to the sebum membrane will make the skin more sensitive, and hot and cold will stimulate the skin, resulting in redness and tight skin;
3, red blood: If you exfoliate frequently and use irritating facial cleanser frequently, it will usually damage the sebum membrane. After the sebum membrane is damaged, it will lead to red blood, especially in the external cheekbones, which will not only affect the facial beauty, but even lead to skin deterioration;
4. Itching: After the sebum membrane is damaged, it loses its protective effect on the skin. If you are stimulated by external substances for a long time, such as contact with pollen, animal fur, chemicals, etc. , may cause itchy skin symptoms. It is recommended not to scratch by hand to avoid damaging the skin.
What are the consequences of serious damage to sebum membrane? Symptoms of facial sebum membrane damage.
Sebum membrane, located at the top of stratum corneum, is a weakly acidic protective membrane emulsified by skin and water, which can increase skin moisture, prevent skin moisture loss and keep skin smooth and moist. The moisture in sebum film can keep skin moist, prevent chapping, and prevent oil stains and bacteria from invading deep skin. If you don't pay attention to the protection of sebum membrane, wash your face frequently, exfoliate frequently, and go out without paying attention to sun protection, it will damage sebum membrane.
Once the sebum membrane is damaged, it will lose its protective effect on the skin, and the skin will become dry and tight, and the surface will become rough and very sensitive. When stimulated by cold or heat, the skin will be red and itchy, and obvious red blood will appear on the external zygomatic region. To improve this situation, don't exfoliate easily, choose moisturizing facial cleanser, wash your face no more than twice a day, use toner to adjust pH and repair skin care products.
How to repair sebum membrane injury?
Sebum membrane is the most important layer for skin to lock water, which can effectively lock water, prevent excessive evaporation of skin moisture, prevent a lot of external moisture and some substances from penetrating, and keep skin moisture in a normal state. If the sebum membrane is damaged, it can be repaired from the following aspects:
1, don't wash too much.
Wash your face for about a minute, and get up in the morning and wash your face with clean water or mild facial cleanser. For example, amino acids. If the stratum corneum itself is very thin, it is recommended to wash your face with clear water and spray mild toner in the morning.
2. Don't use exfoliating products.
If the stratum corneum itself is damaged, it will become thinner. Do not use exfoliating products. Exfoliating products will make dead skin cells in the stratum corneum fall off faster, which will easily become thinner and cause allergic symptoms.
Don't care too much about your skin.
Once the skin barrier is destroyed, there are many problems in the skin. It is suggested that after the sebum membrane is damaged, the minimalist skin care method should be adopted to do a good job of hydrating, locking water and diminishing inflammation.
4. Don't wash your face with overheated water.
If the water temperature is too high, the microvessels will expand, resulting in distiller's grains and sensitive muscles. It is better to wash your face at a lower temperature than your body temperature.
