Quick Summary
Antioxidant powerhouse — brightening, collagen support, and UV damage protection
Also called: LAA, Ascorbic Acid, Vit C serum, CE Ferulic
What is Vitamin C (L-Ascorbic Acid)?
L-Ascorbic Acid (Vitamin C) is the most potent form of topical vitamin C and one of the most studied skincare actives. It neutralizes free radicals generated by UV exposure, inhibits tyrosinase to reduce hyperpigmentation, stimulates collagen synthesis, and enhances the efficacy of SPF. At 10–20% concentrations with a pH below 3.5, it provides measurable antioxidant protection and brightening. The CE Ferulic formulation (SkinCeuticals) is the gold standard — Pinnell et al. (2001) demonstrated 8x antioxidant protection.
How It's Made
L-Ascorbic Acid is synthesized via the Reichstein process or fermentation. Formulated in water-based serums at pH 2.5–3.5 for maximum stability and penetration.
