No.3 Skin Softening Serum

Korea ranking #5 serumUS stock

A fermentation-focused serum led by two ferment extracts, bifida and galactomyces, that help soften and smooth skin over time. It has a light, milky feel that sinks in quickly, so it works as an everyday hydrating layer for tired, dull, or uneven-looking skin. A gentle option for most skin types that want a fermented, essence-style step.

More detail

Bifida ferment lysate and galactomyces ferment filtrate make up most of the formula and bring the antioxidant support, hydration, and barrier care that fermented (probiotic) essences are known for. Niacinamide adds brightening, while squalane, glycerin, hyaluronic acid, and panthenol keep skin soft and moisturized, and adenosine supports firmness. The texture is a lightweight, milky fluid that absorbs without a heavy or sticky feel. Apply a small amount to cleansed skin after toner, morning and night, before heavier creams. It's a straightforward, low-irritation step, though a patch test is sensible with fermented ingredients if your skin tends to react.
