Keratosis pilaris is an inherited skin condition, running strongly in many families, sometimes with a generally dry skin (ichthyosis). Keratosis pilaris appears when extra keratin accumulates in the hair follicles. This is usually in childhood, and most obvious during adolescence, often it clears in adulthood. Treatment is usally with diathermy; using a sterile probe the outer layer of skin is removed. The treatment is usually very sucessful.
