TOKYO, March 13 (Bernama-BUSINESS WIRE) — Mitsubishi Corporation Life Sciences Limited (Head Office: Chiyoda-ku, Tokyo Japan; Koji Kishimoto, representative director and president) conducted the clinical study regarding skin brightness in cysteine peptide and published it in Cosmetics 2023, 10, 72. In this study, Mitsubishi Corporation Life Sciences defined glutathione (GSH), cysteinylglycine (Cys-Gly), and glutamylcysteine (-Glu-Cys) as cysteine peptide and performed a randomized, double-blind, placebo-controlled study to investigate the effects of orally administered cysteine peptide on human skin brightness.
The study showed that the group who orally took the cysteine peptide at 45 mg for 12 weeks exhibited arm brightening in a time-dependent manner, and a significant difference was observed compared to the placebo at week 12.
