Sun-damaged skin often manifests itself in the form of age spots, also called liver spots and solar lentigines, which are flat, brown, grayish-brown or black spots on the skin. They appear in a variety of sizes and usually afflict the face, hands, shoulders, chest, back and arms. Sun damage accumulates in your skin over time, including thinning of the skin, broken capillaries, multiple deep wrinkles, excessive brown pigmentation and skin laxity.
