Abstract: The cosmetic of the present invention is a cosmetic that alleviates skin irritation by blending in polypropylene glycol, a specific polar oil, or polybutylene glycol, as well as an ultraviolet absorbent. The present invention also relates to an agent and a method for alleviating irritation by lipophilic drugs. Since the present invention alleviates skin irritation due to ultraviolet absorbents and lipophilic drugs in cosmetics, any amount of ultraviolet absorbents and lipophilic drugs can be blended in cosmetics, and therefore cosmetics that can fully manifest their effects can be provided. Also, it is possible to prepare a safe sunblock cosmetic with superior ultraviolet protection effects because the ultraviolet absorbent is not absorbed through skin.
