Abstract:
A composition for treatment and treatment of certain skin diseases is disclosed. The treatment combines furocoumarins, UV-A radiation, and a benzylidene-camphor derivative. The composition and treatment produces the desirable results of the furocoumarin/UV-A radiation treatment without the undesirable phototoxic side effects.
Abstract:

Abstract:
A photostable cosmetic composition for protecting the human epidermis against UV radiation comprises, in a cosmetically acceptable carrier, from 0.5 to 5% by weight of 4-(1,1-dimethylethyl)-4'-methoxydibenzoylmethane and at least 0.5% by weight of a compound of formula (I): ##STR1## where R stands for an alkyl radical, the molar ratio of the compound of formula (I) to 4-(1,1-dimethylethyl)-4'-methoxydibenzoylmethane being 0.8 or over.
Abstract:
The present invention relates to a cosmetic composition comprising a natural essence containing a phototoxic dose of furocoumarin, and 0.01 to 2% by weight of at least one benzylidenecamphor derivative filtering out UV-A radiation and chosen from among 3-p-oxybenzylidenebornan-2-ones, 3,3'-terephthalylidenedicamphors optionally sulfonated in the 10-position of the camphor, p-(3-methylidenecamphor)-cinnamic acid derivatives, 3,3'-terephthalylidenedicampho-10-sulfonamides or 3,3'-terephthalylidenedicampho-10,10'-disulfonamides.It is also possible to incorporate into the composition a UV-B filter chosen from among: benzylidenecamphor, p-methylbenzylidenecamphor, benzylidenecamphor derivatives containing a quaternary ammonium radical on the benzene nucleus in the para position relative to the bornylidene radical, benzylidenecamphor derivatives sulphonated on the methyl radical in the 10-position of the camphor or in the 3'-position of 4'-position on the benzene nucleus, p-methylbenzylidene-camphor derivatives substituted on the p-methyl group, or other 3-benzylidenecamphor derivatives filtering out UV-B radiation.The effect of the benzylidenecamphor derivative is to deactivate the furocoumarins excited by UV radiation and to reduce their phototoxicity.
