PROBLEM TO BE SOLVED: To provide an oral composition for accelerating generation of Type III collagen having a hydrolyzed egg shell membrane component as an active ingredient, and furthermore provide an oral skin-beautifying composition that enhances skin-beautifying effect by a synergistic effect of Type III collagen and Type I collagen which are used in combination with fish collagen.SOLUTION: A composition having a hydrolyzed egg shell membrane component, particularly hydrolyzed egg shell membrane powder as an active ingredient has higher Type III collagen generation accelerating function than egg shell membrane powder. Furthermore, when fish collagen is used in combination, a skin-beautifying effect is enhanced by a synergistic effect of Type III collagen and Type I collagen, and an excellent oral skin-beautifying composition is generated.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】加水分解卵殻膜成分を有効成分とするIII型コラーゲンの生成を促進するための経口組成物を提供し、さらに、魚コラーゲンと併用して、III型コラーゲンとI型コラーゲンの相乗的作用で美肌効果が高まる経口美肌用組成物を提供する。【解決手段】加水分解卵殻膜成分、特に加水分解卵殻膜粉末を有効成分とする組成物は、卵殻膜粉末よりIII型コラーゲン生成促進機能が高い。さらに、魚コラーゲンを併用すると、III型コラーゲンとI型コラーゲンの相乗的作用で美肌効果が増強され、優れた経口美肌用組成物となる。【選択図】図1
