Skin is the largest organ in the body and weighs between 6 to 9 pounds. It covers a surface area of about 2.5 square yards. Skin carries out many important functions like protecting the internal organs, muscles, blood vessels and nerves by creating a barrier between the outer environment and that inside the body. Skin also helps to regulate body temperature and maintain water and electrolyte balance. It identifies touch and recognizes painful and pleasant stimuli.
Lot of factors like genetics, stress, hormonal changes, diet, environment, weak immune system etc. can cause skin disorders. It is very important to identify the cause of a skin disorder and undergo the required treatment, as a skin disorder can also be an indication of an underlying illness. A skin disorder can not only affect a person physically but emotionally as well, as it may cause inferiority complex and low self esteem.
Acne, psoriasis, dermatitis, sebaceous cysts etc. are some of the common skin disorders.
