8.5/10 ยท serumVita B3 Source
TIAM's brightening hero and the K-beauty answer to The Ordinary Niacinamide 10% + Zinc 1% โ 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.

8.2/10 ยท serumVita B3 Source Serum
TIAM's B3 serum is niacinamide at 10% concentration paired with alpha-arbutin for dual-mechanism brightening โ 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.

8/10 ยท serumAC Fighting Solution
Tia'm's targeted acne serum โ 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.
