Tia’M (pronounced “tee-uhm”) is a cult-favorite Korean skincare brand known for its effective yet gentle targeted formulas. The name, meaning “a twinkle in the eye when you first meet someone,” reflects Tia’M’s mission to help skin radiate from within . Reborn from its original identity as O.S.T C20, the brand has won fans worldwide with hero products like Vita B5 Toner, Vita B3 Source Niacinamide Serum, My Signature Red C Vitamin C Serum, and the AHA/BHA/PHA clarifying toner.
Tia’M is celebrated for combining high-performance actives—like 10% niacinamide + arbutin or 20% pure vitamin C—with calming, skin-repair ingredients, offering visible results for concerns such as brightness, pore control, hydration, and texture. With vegan-friendly, affordable, and science-backed solutions, Tia’M delivers that sought-after “first-glance glow.” Discover authentic Tia’M picks at Vitre Beauty Supply.
