NMF
Natural moisturizing factor
Natural moisturizing factor(NMF) is a combination of hydrating molecules. 
Natural moisturizing factors (NMF) are the substances excreted from skin cells themselves. It is found in the skin cells of the epidermis. 
Natural moisturizing factors (NMF) is very important for the skin. So the cosmetic industry try to add ingredients to simulate the function of natural moisturizing factors (NMF).
The ingredients of the natural moisturizing factors adding in cosmetics are as the following.
l   Lactic acid
     It can help to hydrate.
l   Urea
     It can help percutaneous absorption. The stratum corneum consists 1.5% of the cells.
l   Amino acids
l   PCA. Na
    The hydration ability is better than glycerin. The stratum corneum consists 3-4% of the cells.

76.factors for skin damage(1)

-
Image
There are many factors that cause skin damage. How does the damage result? They may be from the UV light, pollution , and so on. For example, photoaging and free radical. Then the cells are influenced.   photoaging Sunlight will cause phtoaging. Chronically irradiated skin is metabolically hyperactive, thus giving rise to epidermal hyperplasia and neoplasia , increased production of elastic fibers (solar elastosis), accelerated breakdown and synthesis of collagen , and enhanced inflammatory processes. If DNA damaged and a mutation occurs in the gene, the keratinocytes may lose their ability. Free radical and antioxidants Stratum corneum is frequently and directly exposed not only to UVR but also to other outside forces such as air pollutants, chemical oxidants, smoking, and microorganisms . They are the resources of free radicals . If the protection is insufficient, oxidative damage may occur . Then the chronic accumulation of such deviated cell components may result i...

75.The relations of UV light and the molecular in the skin

The relations of UVlight and the molecular in the skin How do light damage skin? Light consists of a spectrum of photons which contain energy that vary according to the wavelength.  The light interacts on the molecular and then changes their chemical structure or on the subatomic level by creating free radicals. Otherwise, not only UV light but also green, blue, and violet light can damage cells. A photon’s energy can be absorbed into the molecule which is then altered. As the absorption of energy, it can also result in electron changes with the generation of free radicals. A free radical is in fact simply an atom with an unpaired electron that starts up a destructive concatenation of chemical reactions. It may end up causing damage in the cell membranes or in the DNA of the cell. The following are the reaction after exposure to UVB, UVA, and blue light. The influence of increased free radical activity DNA strand breaks occur from increased free radical activity....
