FIELD: cosmetology, dermatology. SUBSTANCE: the present innovation deals with either cosmetic or dermatological compositions to protect skin and/or hair against ultraviolet radiation containing light-protective system in cosmetically and/or dermatologically acceptable carrier to be able to filter UV-radiation, and mixture of polyethylenes consisting of one polyethylene with terminal acid carboxylic function and one polyethylene. The present innovation refers, also, to the product for increasing protection factor against UV-radiation consisting of polyethylene with terminal acid carboxylic function in either free or partially or completely neutralized form and one polyethylene. The present innovation enables to obtain compositions with protection indices being higher against compositions with only one light-protective system. EFFECT: higher efficiency of protection. 17 cl, 9 tbl
