Best Vitamin C Serum Recommended by Dermatologists

The best vitamin C serum recommended by dermatologists isn't always the one with the biggest ad budget nor the most expensive. It's the one with the right formula.
Dermatologists assess vitamin C serums using formulation and stability criteria including chemical form, concentration. The most optimal vitamin C comes in the form of L-Ascorbic Acid at 10% to 20% concentration for efficacy without necessary irritation.
