Niacinamida 10% Serum
Principia's bestseller and the product that put Brazilian direct-to-consumer skincare on the map. 10% niacinamide + zinc PCA in a stripped-back formula that's basically The Ordinary's approach with Brazilian R&D. At R$89 (~$18 USD), it undercuts imports by half and delivers the same sebum-regulating, pore-minimizing, post-inflammatory-hyperpigmentation-fading results that make niacinamide the consensus oily-skin active. The minimalist INCI list is the point — no fragrance, no silicones, no filler. Principia is doing for Brazil what The Ordinary did for the West: evidence-based actives at accessible prices.
