Frequently Asked Questions
Is La Roche-Posay Pure Vitamin C10 Serum 30ml worth it?
Mediocre C serum dragged down by alcohol denat. and fragrance in a non-optimal base—decent but not elite. Efficacy score of 4.1 reflects strong 10% ascorbic acid (clinically effective concentration) paired with tocopherol for synergy, physiological pH aiding stability, and neurosensine for tolerance, but deducts for alcohol denat. as third ingredient risking irritation and oxidation of pure C, low salicylic acid placement suggesting sub-1% inefficacy, and silicone-heavy base lacking encapsulation for better delivery[1][2][3][5]. If you're looking for skincare anti aging products or vegan skincare, this is worth evaluating.
