Knowing skin structure will help you to understand the function of the beauty products and determine if a product is right for you.
So, three layers you must be aware of:
- Epidermis (on the top). New cells are created in the lower level and move towards the surface where they die (usually cycle of 30 days). A layer of oil which helps to retain water. That is why moisturizers play an essential role: they fill in the space between dry cells making skin smoother; they retain water; works as a coat protecting skin from the air. Advice: since moisturizers makes difference in how your skin works it is essential to choose the product carefully. Moisturizers help you to hydrate skin making its surface more smooth.
- Dermis (in the middle) 2 proteins: collagen and elastin, determine skin structure, provides with strength and flexibility. People loose collagen with age as a result skin is less firm, rougher, with more wrinkles, sagging. Sebum, an oily substance is formed in glands. Too much sebum results in oily skin.
- Hypodermis (on the bottom) consists of a fat layer, blood vessels and nerves.
