| Verdict | COSRX big 2026 launch and a direct answer to The Ordinary 10% Niacinamide. The 15% concentration is on the high end of what most users can tolerate, but the minimalist formula and pH balance mean it actually feels usable. For pigmentation, visible pores, and sebum regulation, this is a strong workhorse serum at a fair price. | 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. |
