Overview. YS-012 is produced by fermenting premium Rhodiola rosea raw material with a proprietary yeast strain under controlled bioprocessing conditions. Fermentation is a natural bio-reactor: yeast enzymes break down the plant's macromolecular structures, liberating bound actives and generating new functional metabolites. The result is a light brown to brown, crystal-clear liquid (pH 4.0–6.0) naturally enriched with bio-transformed salidroside, flavonoids and ergothioneine — the long-lived "longevity vitamin" prized in modern skin care — presented in a form that is gentle, skin-friendly and formulation-ready.
Mechanism. The fermentation process converts glycosylated and protein-bound actives into smaller, more permeable molecules, markedly enhancing skin bioavailability versus conventional extracts. Salidroside and flavonoids provide broad-spectrum antioxidant and anti-glycation defense along the aging pathway; ergothioneine — a microbial metabolite accumulated during fermentation — offers exceptional oxidative-stress protection and mitochondrial support; and yeast-derived postbiotics and amino acids help soothe irritation and reinforce the skin barrier. This multi-pathway profile makes the filtrate equally effective in preventive anti-aging care and in calming, repairing routines.
Applications. YS-012 is extremely versatile: recommended at 0.1%–1.0% in cleansers and toners, and at 1.0%–5.0% in serums, essences and treatment products where the fermented narrative can be fully expressed. It is ideal for antioxidant essences, barrier-repair toners, soothing lotions and "fermented skincare" ranges, and it is fully compliant for cosmetic use in the EU and US.
