An objective of the invention is to provide a sunscreen cosmetic that increases the ultraviolet protection power of ultraviolet protectants, thereby achieving high ultraviolet protection power using only a small amount of ultraviolet protectants, while simultaneously providing an excellent texture and placing little strain on the skin. The sunscreen cosmetic according to the present invention contains the following components (A) to (C): (A) an ultraviolet protectant; (B) silica having a particle size of 0.3 to 1 .Math.m; and (C) a powder having a particle size of 1 to 30 .Math.m; wherein the (C) powder is of one or more types selected from the group consisting of silica, aluminum starch octenyl succinate, cellulose or derivatives thereof, waxes, mica, sericite and biodegradable resins.

An anti-oxidizing agent or skin stress suppressing agent was provided with.

An anti-oxidizing agent or skin stress suppressing agent comprising a wavelength conversion substance as an active ingredient; a composition and a product comprising the anti-oxidizing agent or skin stress suppressing agent; and a method for suppressing oxidization and skin stress of skin using thereof were provided with. The present invention can exhibit a desirable effect on skin by effectively making use of ultraviolet light to suppress skin cells.
