Beyond sun protection factor testing

International Journal of Cosmetic Science, 2004
SynopsisUltraviolet radiation in sunlight produces a range of acute and chronic adverse effects on the skin including sunburn, photosensitivity rashes, immunosuppression, photoageing and carcinogenesis.

Durability of the sun protection factor provided by dihydroxyacetone

Photodermatology, Photoimmunology & Photomedicine, 2004
Background/Purpose: The sunless tanning agent dihydroxyacetone (DHA) is known to protect against longwave ultraviolet radiation (UVA) and visible light. Recently, our laboratory has shown that DHA in addition offers a modest sun protection factor (SPF) in humans. We conducted this study in order to investigate the durability of the SPF provided by DHA.

Sun protection factors

International Journal of Cosmetic Science, 1985
SynopsisThe absorption of ultraviolet light by a film of sunscreen product on the surface of the skin is considered from a theoretical standpoint. It is apparent that Beer‐Lambert's Law would predict protection factors in excess of the actual factors by many orders of magnitude.
