UVA rays are those mainly responsible for skin ageing. They represent 95% of the UV rays that reach the skin. They are present throughout the year at all latitudes and can pass through clouds and windows. They deeply alter the skin's structure. Like UVB's, UVA rays are involved in the formation of skin cancers.
