The invention relates to insoluble organic compounds containing one or more aryl vinylene ketone groups, for screening out UV radiation, in the form of fine particles with an average size of between 10 nm and 5 &mgr;m, and also to their use for protecting the skin, the hair or materials that are sensitive to UV radiation. The said compounds may be obtained by a process of grinding coarse particles in the presence of one or more suitable surfactants.

The invention relates to the use of at least one agent for screening out light radiation with a wavelength ranging from 370 to 500 nm as an agent for inhibiting the degradation of endogenous carotenoids present in the skin. The invention is useful for treating skin disorders caused by sunlight (e.g., solar urticaria, actinic dermatitis and pigmentation marks). The invention also relates to novel aminoaryl-vinyl-s-triazine compounds and to the use thereof as agents for screening out light radiation ranging from 370 to 500 nm.
