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.
Claims23
A method for tanning skin comprising applying liposomes containing at least one DNA repair enzyme to skin in an amount effective to produce tanning or melanin production and exposing the skin to UV radiation, said applying of the liposomes occurring before and/or during and/or after the exposure to said UV radiation.
A method for inducing melanin production by melanocytes comprising administering liposomes containing at least one DNA repair enzyme in an amount effective to induce melanogenesis to melanocytes and exposing the melanocytes to UV radiation, said administering of the liposomes occurring before and/or during and/or after the exposure to said UV radiation.
A method for protecting the skin of an individual susceptible to UV-induced damage comprising applying liposomes containing at least one DNA repair enzyme to the individual's skin in an amount effective to produce tanning or melanin production and exposing the individual's skin to UV radiation whereby the individual's skin becomes tanned, said applying of the liposomes occurring before and/or during and/or after the exposure to said UV radiation.
