Sun damage is a broad term that describes skin changes that occur as a result of sun exposure. Ultraviolet (UV) light from the sun damages skin cells. In addition to increasing the risk of skin cancers, sun exposure causes premature ageing of the skin.

In fact, research has shown that sun exposure accounts for more than 90% of skin ageing. Clinically, sun damage, also known as photoageing or dermatoheliosis, is the appearance of wrinkles, pigmentation, broken capillaries, rough skin texture, laxity and thinning of the skin.

The treatment of sun damage involves sun protection to prevent further damage and treatments that reverse the signs of photoageing.
