Fermented yeast.
The absolute legendary pioneer of low-pH skin washing across Malaysia and Southeast Asia. COSRX completely dismantled old-school high-pH alkaline cleansing loops by launching this physiological pH 5.5 wash. It utilizes an ultra-mild, non-stripping anionic-amphoteric surfactant matrix (Sodium Lauroyl Methyl Isethionate and Cocamidopropyl Betaine) to lift surface dirt softly. It leaves the critical moisture lipid bricks completely untouched. Packed with **0.5% Styrax Japonicus botanical extract** and natural **Tea Tree Oil**, it targets acne bacteria corridors during washing, rinsing away to leave a thoroughly clean, perfectly balanced fresh satin baseline.
A breathtakingly advanced, ultra-premium fermentation essence. It utilizes a massive, multi-tiered microbiome complex featuring Galactomyces, Saccharomyces, Lactobacillus, and Bifida ferment filtrates. By driving these bio-ferments deeply into the skin alongside Polyglutamic Acid and Beta-Glucan, it drastically shifts the dermal environment to support profound cellular repair, hydration, and visible brightening safely.
