The ingredient narratives reshaping clean beauty.
Galactomyces Ferment Filtrate
aka pitera · galactomyces · saccharomycopsis ferment
SK-II Pitera ('discovered in a sake brewery, glowing-handed monks') built the entire luxury fermented-skincare category on this single yeast filtrate. Cosmax-tier K-beauty supplied the mass version through SU:M37, COSRX Galactomyces 95, and Missha's First Treatment Essence. Galactomyces ferment is rich in amino acids, vitamins, minerals, and organic acids; the AhR (aryl hydrocarbon receptor) activation pathway is the proposed 'glow' mechanism.
- improves skin radiance, pore appearance, and texture (clinical evidence in SK-II–level trials)
- humectant amino acid and PCA load
- supportive of microbiome balance
- SK-II Facial Treatment Essence (Pitera)
- first essences
- radiance toners
Effective at 30–95% as the aqueous base of an essence. Cold-process to preserve ferment activity. Pairs natively with niacinamide and HA.
A small subset of users with malassezia-driven skin conditions (seb derm, fungal acne) may flare from yeast ferments — patch test if relevant.
Trusted within K-beauty fermented spectrum; sometimes flagged on fungal-acne-aware lists.
