NK‑063 Sake Lees– Rice Ferment Filtrate | Triple Action: Whitening, Anti‑Wrinkle & Barrier Repair
BEN‑063 is a clear, concentrated filtrate obtained from the fermentation of rice (sake lees). It retains the rich nutrients of traditional sake lees – including glucosylceramides, multiple amino acids, and γ‑aminobutyric acid (GABA) – but contains no alcohol, only a pleasant, mild sake aroma. This makes it ideal for sensitive skin, hormone‑imbalanced skin, and even water‑free formulations.
