Functions of skin



Functions of skin are a lot. Many cosmetics are for skin care. Skin is the very important organ which covers the human body surface. It is not only the skin out the body, but also include the mouth cavity and the other private skin.
Skin dominates 16 % weight of the body. The functions of skin are as the following.
Protection:
Block the damage such as physical, chemical, biological hurts
Sensation
React the heat and cold, touch, pain, and so on.
Adjust body temperature
The body could decrease the temperature by losing water through skin. When water evaporate to air, it also take away the heat.
Excretion
Medicine, toxic chemical, enzyme and hormone are secreted by the other organ and excrete from skin. The results would be like sweat, urine, loss of hair and ruining nails, etc.

76.factors for skin damage(1)

-

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 in t

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. W e
