Pigmented spots including age spots or "liver spots" may appear in sun-exposed areas. Aging skin looks thinner, paler, and clear (translucent). The remaining melanocytes increase in size.

Blue-eyed, fair-skinned people show more aging skin changes than people with darker, more heavily pigmented skin. Natural pigments seem to provide some protection against sun-induced skin damage.

Skin changes are related to environmental factors, genetic makeup, nutrition, and other factors. Watch this video about: Components of skin
