| Verdict | 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. | At-home microneedling in a bottle. The spicules are made from freshwater sponges and feel like tiny prickles as you massage them in — the sensation is alarming the first time but completely normal. Over 4-8 weeks, it genuinely improves texture, reduces pore visibility, and smooths scarring. Start with the 100 concentration before graduating to 300 or 700. |
