Trust Score: 8/10
Six bucks for a cult-classic serum with a decade of receipts. Your wallet and your pores are both winning.
BuySkip's analysis found The Ordinary Niacinamide 10% + Zinc 1% to be one of the most legitimately well-supported budget skincare products on the market — and at roughly $5.90 for 30ml, it's almost absurdly cheap for what it delivers. Independent community reviews across multiple Reddit skincare subs consistently report reduced oiliness, improved pore appearance, and brighter skin tone with consistent use, backed by PubMed-confirmed safety data on niacinamide at this concentration. The one real caveat: a meaningful subset of users — including Lab Muffin Beauty Science — report that the 10% concentration causes cystic breakouts or flushing in sensitive skin, so patch-test first. Buy from authorized retailers only to avoid counterfeits.
