The skin-beautifying agent is characterized in containing a hydrolyzate of whey protein as an active ingredient. Using a whey protein hydrolyzate having the characteristics of a molecular weight distribution of 10 kDa or less, a main peak of 200 Da-3 kDa, APL (average peptide length) of 2-8, free amino acid content of 20% or less, and a β-lactoglobulin antigenicity of 1/10,000 or less, in particular, provides a skin-beautifying agent of low allergenicity and low bitterness.
A method of treating dry skin, comprising applying whey protein hydrolysate to the skin of a person who has dry skin, wherein the whey protein hydrolysate is obtained by exposing a whey protein to a heat-resistant protease at a temperature of 45 to 70° C. and has a free amino acid content of 20% or less by weight based on the total components of the hydrolysate.
A method of moisturizing or protecting mammalian skin, comprising applying whey protein hydrolysate to the skin of a mammal with dry skin, wherein the whey protein hydrolysate is obtained by exposing a whey protein to a heat-resistant protease at a temperature of 45 to 70° C. and has a free amino acid content of 20% or less by weight based on the total components of the hydrolysate.
A method of moisturizing or protecting mammalian skin, comprising applying a cosmetic in the form of an emulsion, cream, lotion, or pack and comprising a whey protein hydrolysate obtained by exposing a whey protein to a heat-resistant protease at a temperature of 45 to 70° C.,
