An object of the present invention is to provide a hyaluronic acid production promoter which has no safety issues. Another object of the invention is to provide hyaluronic acid production promoting foods and beverages and hyaluronic acid production promoting cosmetics containing such a substance. A angiogenin and/or a angiogenin degradation product obtained by degrading a angiogenin using a protein degrading enzyme such as pepsin or pancreatin is used as an active ingredient of the hyaluronic acid production promoter, hyaluronic acid production promoting food or beverage, or hyaluronic acid production promoting cosmetic. This angiogenin or angiogenin degradation product has the effect of increasing the amount of hyaluronic acid.本發明之課題在於提供於安全性方面沒有問題的玻尿酸產生促進劑。又,本發明之課題在於提供摻合了如此的物質的玻尿酸產生促進用飲食品及玻尿酸產生促進用化妝料。係將血管生成素(angiotenin)及/或血管生成素以胃蛋白酶或胰酶等蛋白質分解酵素分解而得之血管生成素分解物作為玻尿酸產生促進劑、玻尿酸產生促進用飲食品及玻尿酸產生促進用化妝料的有效成分。此血管生成素或血管生成素分解物有增加玻尿酸量的作用。
