| age spot | <dermatology> A skin disorder seen with aging (or sun exposure) where there are flat patches of increased pigmentation on the skin. They are nonserious, benign and generally more important cosmetically. The most commonly appear on sun exposed areas such as the forehead and the back of the hands. Avoidance of the sun and the use of a sunscreen (SPF of 15) can reduce the incidence of these lesions. Creams and lotions are available which bleach the skin. Cryotherapy can be used in some cases.
