The Triple Ferment System in SEACRET Renewal Multi Acid Night Serum combines three fermented actives: Bifida Ferment Lysate (a probiotic lysate for skin surface balance), Saccharomyces/Xylinum/Black Tea Ferment (for the feel of comfortable, radiant skin), and FERMENT 21 (the patented Dunaliella-based complex). Together they provide a fermented layer that helps buffer the AHA/BHA acid system, which is how the serum supports overnight renewal without the redness under-buffered acid serums can produce.
Key benefits: Helps support a calm, balanced-looking skin surface overnight | Provides a fermented buffer layer alongside the acid complex | Three ferments working across skin cycles for cumulative radiance

Select SEACRET formulas include exfoliating acids at cosmetic, well-tolerated concentrations. In Renewal Multi Acid Night Serum, the AHA component (Glycolic, Lactic and Malic Acids) contributes to the look of a smoother, more even skin surface, while the BHA component (Salicylic Acid) helps address the appearance of congested pores. A triple-ferment buffer system is built into the formula specifically to support comfort during the acid cycle. Pregnancy advisory: contains Salicylic Acid; consult your OB before use during pregnancy or nursing.
