Many people know what dead skin is, but know very little about it. The dead skin layer (stratum corneum) is the outermost layer of the epidermis, mainly composed of 15 to 20 layers of dead cells without cell nuclei. It helps to reduce water evaporation and can even absorb water to keep the skin moisturized. 1. Basic Introduction The cells of the dead skin layer contain keratin. It helps reduce water evaporation and even absorbs water to keep the skin moisturized. Due to the water absorption of keratin, the skin of many animals (including humans) will become wrinkled after being soaked in water for a period of time. The dead skin layer generally ranges from 10 to 40 microns, depending on how much protection the corresponding body part needs. For example, the palms, soles of the feet and other areas that have more contact and friction with the outside world will have a thicker dead skin layer. The dead skin layer of reptiles is a permanent tissue that will only fall off and be replaced during periods of rapid growth (such as peeling). Their dead skin layer contains beta keratin, which makes their epidermis much tougher than that of other animals. 2. Repair Excessive exfoliation will cause the dead skin layer to become very thin, making the skin sensitive and even causing red blood streaks in severe cases. If it is caused simply by using exfoliating products, it will heal on its own after stopping use. The dead skin in the red blood-streaked areas is no longer there, as it has been destroyed. There are two types of red blood: exogenous and endogenous. Exogenous red blood streaks are caused by products containing hormones, antibiotics, fruit acids and other ingredients. Daily prevention of red blood streak skin: 1. Strengthen skin exercise, wash your face with warm water frequently to increase skin tolerance; 2. Try not to use cosmetics containing heavy metals to avoid pigmentation and toxins remaining on the epidermis; 3. Try not to do some laser beauty projects and do not damage the dead skin layer of the skin; 4. Avoid using corticosteroid ointments for local skin allergies; 5. Open windows more often to ventilate and reduce skin irritation; 6. Massage your face regularly to promote blood flow and help enhance the elasticity of capillary walls; 7. Pay attention to moisturizing your skin and prevent it from drying out and peeling; 8. Avoid spicy food, tobacco, alcohol, etc. 3. Exfoliation (1) Apply an appropriate amount of exfoliating product to your thoroughly cleansed face, and then use your fingertips to slide the product around your face in circular motions. (2) Massage the oily T-zone, sides of the nose, and around the lips in particular to ensure that the areas where dirt easily accumulates are thoroughly cleaned. (3) Rinse your face with plenty of clean water to remove all the dirt and dead skin on your face, revealing fair and radiant skin. (4) Then use a cotton pad soaked in a large amount of lotion to gently pat your facial skin. This will make the skin texture more refined and the pores smaller and less visible. |
