Brand note
SkinCeuticals is the brand dermatologists point to when they want to talk about clinically tested, patent-backed formulas — specifically around vitamin C and antioxidants. The C E Ferulic serum is the anchor here, and it's consistently described as the most studied vitamin C on the market, with a 15% concentration of pure ascorbic acid plus vitamin E and ferulic acid. But the praise comes with real friction: it's expensive, the packaging isn't airless, and at least one creator flags the 15% concentration as too strong for skin of color.
