METHOD OF PROMOTING SKIN COLLAGEN PRODUCTION
It is intended to provide a skin collagen production promoter, foods and drinks for promoting skin collagen production and cosmetics for promoting skin collagen production which are useful in preventing skin chapping, wrinkles, worsening in skin fitness, etc. Namely, a skin collagen production promoter, foods and drinks for promoting skin collagen production and cosmetics for promoting skin collagen production which contain as the active ingredient(s) a milk-origin basic protein fraction and/or a basic peptide fraction obtained by digesting the above-described basic protein fraction with a protein digesting enzyme such as pepsin or pancreatin. The above basic protein fraction and basic peptide fraction have an effect of increasing skin collagen level.
1 . A method of promoting skin collagen production to treat skin wrinkling, skin sagging, skin dryness feeling and/or skin chapping, said method comprising orally administering to a subject in need thereof a pharmaceutical composition comprising a skin collagen production promoter comprising, as an active ingredient, a milk-derived basic protein fraction and/or a basic peptide fraction obtained by degradation of the milk-derived basic protein fraction with a protease;
wherein said skin collagen production promoter promotes skin collagen production and improves skin wrinkling, skin sagging, skin dryness feeling or skin chapping when orally administered or topically applied to the skin; and
wherein said skin collagen production promoter promotes skin collagen production and thereby treats skin wrinkling, skin sagging, skin dryness feeling or skin chapping.
2 . A method of promoting skin collagen production to treat skin wrinkling, skin sagging, skin dryness feeling and/or skin chapping, said method comprising orally administering to a subject in need thereof a food or beverage product for promoting skin collagen production having incorporated therein a milk-derived basic protein fraction and/or a basic peptide fraction obtained by degradation of the milk-derived basic protein fraction with a protease;
wherein said skin collagen production promoter promotes skin collagen production and improves skin wrinkling, skin sagging, skin dryness feeling or skin chapping when orally administered or topically applied to the skin; and
wherein said skin collagen production promoter promotes skin collagen production and thereby treats skin wrinkling, skin sagging, skin dryness feeling or skin chapping.
3 . A method of promoting skin collagen production to treat skin wrinkling, skin sagging, skin dryness feeling and/or skin chapping, said method comprising topically applying to the skin of a subject in need thereof a cosmetic composition for promoting skin collagen production having incorporated therein a milk-derived basic protein fraction and/or basic peptide fraction obtained by degradation of the milk-derived basic protein fraction with a protease;
wherein said skin collagen production promoter promotes skin collagen production and improves skin wrinkling, skin sagging, skin dryness feeling or skin chapping when orally administered or topically applied to the skin; and
wherein said skin collagen production promoter promotes skin collagen production and thereby treats skin wrinkling, skin sagging, skin dryness feeling or skin chapping.
4 . The method according to claim 1 , wherein said milk-derived basic protein fraction or basic peptide fraction is administered at a dosage of at least 20 mg/day.
5 . The method according to claim 2 , wherein said milk-derived basic protein fraction or basic peptide fraction is administered at a dosage of at least 20 mg/day.
6 . The method according to claim 3 , wherein said milk-derived basic protein fraction or basic peptide fraction is administered at a dosage of at least 20 mg/day.
