Performance notes
Galactomyces Ferment Filtrate is a fermentation-derived ingredient widely used in Korean skincare to support hydration and may help with the look of smoother, more even-toned skin over time. Adenosine is commonly included in essence-style products to support the skin's overall appearance. Together, this formula is best understood as a hydrating prep step meant to be layered before serums and moisturizer rather than an exfoliating or acid-based toner.

Frequently asked questions
What does Galactomyces Ferment Filtrate do in a toner?
Galactomyces Ferment Filtrate is a fermentation-derived ingredient popular in Korean skincare, generally included to support hydration and may help with the look of a smoother, more radiant complexion. It does not exfoliate the way an acid toner would, so its role here is more supportive than treatment-based.
Is this a toner or an essence?
The product is marketed as an essence toner hybrid, meaning it is meant to be used like a toner after cleansing but carries a slightly thicker, more concentrated feel typical of a K-beauty essence step, which is layered before serums.
