Insulin Dermatitis of a Teenager
Majid Ali, M.D.
Insulin in excess is toxic to the skin and causes areas of inflammation with dryness , roughening of texture, and excess pigmentation often associated with loss of pigmentation. I coin the term “insulin dermatitis” for such skin changes. Insulin dermatitis clears up when excess insulin (hyperinsulinism) is reversed. The photograph below illustrates features of insulin dermatitis in an 18-year-old girl.
