摘要： A novel anti-sunburn skin-care preparation, such as creams, foundations, milky lotions and the like, is proposed which contains, as the ultraviolet-absorbing and -shielding ingredient, a salt of ellagic acid with a polyvalent metal, e.g., calcium, barium and magnesium. The skin-care preparation is free from the problem of irritation and sensitization of human skin and exhibits excellent anti-sunburn effect with durability.
