Skin and Hair Disorders

Skin is regarded as one of the largest system in the human body. It functions as a protective cover, and maintains homeostasis with the internal environment in form of thermoregulatory system and works as insulation. It is divided in itself into 3 layers for various functions. Skin protects the body against the harmful disease causing agents from outside, synthesizes vitamin D. It has its characteristic pigmentation which gives the identity and ethnicity of the person. Skin disorders pose a major social stigma owing to the cosmetic effect. Few are short lived, few are permanent, and some are acquired or congenital (by birth), some are auto immune i.e. self-destructive in nature.
