Vitamin C for Brightness & Firmness

by ThankMeNow Editors on Sep 12, 2025
Vitamin C, the most celebrated antioxidant in dermatology, brightens dull skin, supports collagen formation, and shields against daily oxidative stress. This dermatologist-backed guide explains exactly how to choose the right form—from potent L-Ascorbic Acid to gentler derivatives like MAP and SAP—how to layer it with Niacinamide and SPF for protection, and how to store it to preserve stability.
