The best vitamin C serum recommended by dermatologists is often one that contains a stable form of vitamin C, such as L-ascorbic acid and is formulated with additional antioxidants and skin-nourishing ingredients.

Brands like SkinCeuticals C E Ferulic and Drunk Elephant C-Firma Day Serum are frequently recommended for their potency, stability, and proven efficacy in brightening skin, reducing hyperpigmentation, and protecting against environmental damage.
