ge spots usually begin to appear on sun-exposed areas such as the back, chest, arms and hands in your early 30s. Although they may look similar to moles, the two are very different. Moles are genetically predetermined, while age spots are the result of cumulative sun exposure throughout your life.
A product of sun damage, they result from an overproduction of melanin as the skin attempts to protect itself from UV light. These flat lesions are tan or brown and appear most frequently on the cheekbones, temples, nose, shoulders, décolleté and hands.
