Composition comprising collagen peptide, elastin peptides and proteoglycans

The present invention addresses the problem of providing a composition with which a skin beautifying effect can be demonstrated even if collagen peptide intake is reduced. A composition that effectively demonstrates a skin beautifying effect, even with low-concentration collagen peptide, can be provided by making the weight ratio of collagen peptide, elastin peptide, and proteoglycan contained in the composition a prescribed ratio.
