su:m37 Fermentalift Boosting Toner is a 150ml fermented Korean toner that hydrates and preps skin, leaving it soft, balanced and radiant.
What it is
A lightweight fermented toner from su:m37, one of Korea's best-known fermentation-led skincare houses. The 150ml bottle delivers a watery, fast-absorbing texture that sits comfortably on all skin types, including sensitive skin. It is the first step in the four-piece Fermentalift routine.
What it does
Fermentalift Boosting Toner delivers an immediate first layer of hydration to clean skin, helping the serum, emulsion and cream that follow absorb more evenly. Naturally fermented botanical extracts help skin look fresh, smooth and radiant, while the balanced formula leaves the complexion feeling comfortable rather than tight.

Who it is for
Suitable for all skin types, including dry, normal, combination and sensitive skin. A good choice if you want a hydrating first step, prefer fermented skincare, or are building a complete Korean layering routine.
