Filtrate from fermented rice rich in amino acids, vitamins, and antioxidant metabolites; laboratory and animal studies show reduced melanin synthesis and increased collagen and elastin, though human clinical data remains limited.
Why we tier this anecdotal
3 cited papers across 2 countries. Most of what's cited here is mechanism-level or in-vitro work. We track this as Anecdotal until controlled clinical trials accumulate.
