A condition that usually causes rough patches and small, acne-like bumps on the skin. This tends to develop when the skin produces too much of the protein called keratin, which can block hair follicles and cause bumps to develop. Sometimes referred to as “chicken skin”, keratosis pillars presents itself on the arms, thighs, cheeks, and buttocks. These white and sometimes red bumps can appear to be rash-like, but tend not to hurt or itch. Lack of exfoliation or treatments can prolong the life-span of this condition.
