The skin functions are carried out by the largest organ in the human body. It regulates our body temperature through sweating to reduce heat and constricting pores, goose bumps, to reduce heat loss.
Five main Skin Functions
Barrier Skin Functions
It acts as a mechanical barrier in that it prevents bacteria and viruses from entering the body. Langerhans cells which are found within the dermis, engulf and destroy invaders and matter foreign to the body. It also has a waterproof barrier formed by sebum and keratin layers in the upper surface of the skin. In addition the skin has Melanocytes which are cells that protect us from ultraviolet light.
Vitamin D
Skin produces Vitamin D in the presence of sunlight and ultra violet radiation needed for the absorption of calcium and phosphate.
Temperature regulation
Your skin regulates body temperature. This is one of the most important skin functions. Considerable heat is lost through the skin. Even under extreme conditions of high temperature and exercise, our skin tends to make body temperature normal. The production (evaporation) of sweat in the skin cools us down when exposed to too much heat.
Information
Nerve endings in the skin provide the sense of touch, temperature and sensation thereby providing up information about our immediate surrounding and environment.
Waste Removal
Another skin function is to remove waste product and excess salt from the body though sweating. Sweat includes waste products in solution.
Skin with blocked and clogged pores is unhealthy is not just a beauty problem, but can inhibit the skin functions. Proper care of your skin is important not only to your personal beauty but also to overall health. Taking care of your skin now will pay off as you grow older retaining its suppleness and luster. You also know your skin type in order to look after it properly.
