Yeast fermentation product containing amino acids, vitamins, and minerals. The core ingredient in SK-II Pitera. Moisturizes and evens skin texture.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
Small clinical studies (mostly industry-sponsored) show texture improvement, hydration, and pigmentation lightening. Filtrate composition standardization is difficult. No independent rigorous RCTs.
Saccharomyces Ferment Filtrate is a fermentation product of food yeast Saccharomyces cerevisiae or related strains. Contains amino acids, oligopeptides, B-vitamins (B1, B2, B3, B5, B6, B9, B12), minerals (zinc, copper, selenium), β-glucans, nucleotides. In global cosmetics known through the legendary SK-II Pitera ingredient (Pitera is actually galactomyces, but commercial saccharomyces filtrates work analogously). Where applied. Essence toners, serums and creams of Asian origin (5-50%), brightening lines, mature-skin products, recovery masks. In Spain on shelves of Sesderma Azelac Ru, certain SK-II analogues in large department stores (El Corte Inglés). Evidence base. Bissett 2006 (n=43, 8 weeks) showed improved facial skin texture, tone and elasticity after using a toner with 90% Pitera. Lim 2014 in atopic patients – reduced TEWL and improved barrier. Evidence for specific commercial Pitera (galactomyces) is stronger than for general saccharomyces filtrate; evidence quality for individual saccharomyces filtrates – B/C. Mechanism. β-glucans stimulate collagen synthesis in fibroblast cultures and activate skin innate immunity. Amino acids and B-vitamins work as cofactors of cellular metabolism. The effect is complex, not reducible to one compound. Safety. CIR confirmed safety of saccharomyces filtrates in cosmetics (Final Report 2015). Hypoallergenic for most users. People with yeast allergy (rare) or yeast-based irritable bowel syndrome – use with caution. Pregnancy and lactation – safe. Food yeast, natural origin, no systemic absorption. No restrictions.
