What is it?

Hypertrophic scar is a raised, thickened and wide scar that occurs as a result of skin injury. Hypertrophic scar is an abnormal wound healing following injury or trauma. It is caused due to excessive production of collagen, either because of skin tendencies or because of wound infection, inflammation or tension of motion. Hypertrophic scars typically don’t grow beyond the boundaries of the original skin injury. Keloid scars are smooth, benign, and hard growths. Keloid scars, as opposed to hypertrophic scars, grow beyond the boundaries of the original incision or wound. Both of these disorders are more common in people with dark skin. Skin atrophies diseases are conditions in which there is a depletion of the dermis, and sometimes the epidermis, of the skin. Sometimes, the adipose tissue is thickened. It is usually a manifestation of aging, and is most noticeable in the face, arms, and hands. UV exposure, smoking, alcohol consumption, lack of exercise,and medications such as corticosteroids can also cause skin atrophy.
