Vita B3 Source

TIAM's brightening hero and the K-beauty answer to The Ordinary Niacinamide 10% + Zinc 1% — but with alpha-arbutin instead of zinc for a more targeted melanin-inhibiting angle. At 10% niacinamide + 2% alpha-arbutin, this is a serious clinical-concentration dark spot serum at a budget Korean price. The My Signature C Source's quieter, more niacinamide-forward sibling.

Vita B3 Source Serum

TIAM's B3 serum is niacinamide at 10% concentration paired with alpha-arbutin for dual-mechanism brightening — niacinamide inhibits melanin transfer while arbutin inhibits tyrosinase production. Under $16 for a formula that addresses hyperpigmentation from two angles. The K-beauty brand that competes with The Ordinary on price while delivering better textures and more targeted formulations.

AC Fighting Solution

Tia'm's targeted acne serum — salicylic acid (BHA) + tea tree leaf oil + Centella asiatica + niacinamide in a multi-pathway acne formulation. The combination of synthetic salicylic + natural tea tree gives this a genuine antimicrobial + exfoliating action without crossing into irritation territory.
