Abstract
A method for tanning skin is provided in which liposomes containing a DNA repair enzyme are administered to skin in combination with exposure of the skin to UV radiation. The result is an enhanced level of melanin production, i.e., more tanning than achieved by UV radiation alone. The administration of the DNA repair enzymes in liposomes also reduces the level of DNA damage caused by the UV exposure. Accordingly, both the tanning response is increased and the deleterious effect of UV exposure is decreased. The method can be used by the general population as well as by individuals whose skin is susceptible to UV-induced damage.
