La Roche-Posay Vitamin C12 Serum vs e.l.f. Skin Bright Icon Vitamin C Serum

Both are fragrance-free brightening serums, but they use different vitamin C. The La Roche-Posay uses 10% pure L-ascorbic acid with salicylic acid and Neurosensine, aimed at sensitive skin and fine lines. The e.l.f. uses 15% 3-O-ethyl ascorbic acid with vitamin E and ferulic acid, a more stable derivative that suits oily and combination skin. The e.l.f. has the higher rating from far more owners; the La Roche-Posay has the dermatologist-backed name and the soothing ingredient.

• Choose the La Roche-Posay Vitamin C12 if your skin is sensitive or reactive and you want pure vitamin C with a soothing agent and a pore-clearing acid in one step.
• Choose the e.l.f. Bright Icon if you have oily or combination skin and want a stable vitamin C derivative paired with vitamin E and ferulic acid at a higher stated percentage.
