collagen oligopeptides melanin hydroxyproline skin aging whitening effects

Studysummary This study found that collagen oligopeptides from puffer skin may reduce skin melanin and increase hydroxyproline content in guinea pigs, suggesting potential skin whitening and anti-aging effects. Our plain-language summary of this paper — not a Tressless recommendation.

The study investigated the skin care and whitening effects of collagen oligopeptides from puffer skin on male guinea pigs over 30 days. Results showed that these oligopeptides reduced melanin granules and increased hydroxyproline content in the skin, suggesting potential benefits in delaying skin aging and enhancing whitening effects. No pathological changes were observed in the guinea pig skins.
