Effective Treatment for Skin

Skin is composed of two layers. The surface layer that you see is a thin covering called the epidermis. Below the epidermis is a thicker layer, the dermis. The dermis contains many specialized structures such as hair follicles and sweat glands . Below the dermis is a layer of fat that is called subcutaneous fat.The surface skin layer, the epidermis, is a very active layer of cells. Cells at its base are continuously dividing to produce new cells, which gradually die as they fill up with a hard substance, keratin. As they die, they move up to the skin surface, to be shed or worn away by rubbing from your clothes, washing, or handling things. In fact, virtually any movement that causes friction also causes some skin cells to be rubbed away. The continuous production of cells at the base of the epidermis keeps up with the continuous loss of cells from its surface. It takes an average of one month for any single epidermal cell to complete the journey from base to surface. On parts of the body where pressure and friction are greatest, the epidermis is thicker, and the journey takes longer. A number of skin problems are caused by a fault in the constant turnover of skin cells. In psoriasis, for example, there is an abnormal build-up of surface cells because there are increased numbers of cells being produced and pushed up from the base of the epidermis.
