Effect of Oral Administration of Defatted Chicken Skin Powder on Dry Skin in Humans

Abstract

We investigated the effects of defatted-dried chicken skin powder (DCS) containing sphingomyelin (SM) on human facial skin conditions. A placebo-controlled, double-blind 12-week study of DCS (1 g/day ; SM2 mg/day) was conducted on 36 female volunteers who tend to have dry skin. In the DCS group, the moisture of the stratum corneum of cheek tended to increase after 12 weeks. In the subjects whose moisture of cheek was less than 35 arbitrary unit, the DCS group was significantly higher than the placebo group. After 12 weeks, skin elasticity showed significantly increase in the DCS group compared with 0w. These results indicate that the ingestion of DCS improves dry facial skin.

“…In 2013, Kawamura et al examined the effects of dried chicken skin powder containing sphingomyelin on human facial skin [ 55 ]. In a placebo-controlled, double-blind 12-week study, the treatment was administered at 1 or 2 mg per day in 36 female volunteers who tended to have dry skin.…”

After 12 weeks, skin elasticity showed a significant increase when compared to controls and the results (based upon quantitative endpoints) indicated that ingestion of the dried chicken skin powder containing sphingomyelin improved dry facial skin in the human subjects [ 55 ].…”
