Rodan + Fields: an anhydrous 10% ascorbic acid formulation

The American company has launched Pure C serum, a dermo-cosmetic solution targeting skin longevity through a 10% concentration of pure L-ascorbic acid. The technical cornerstone of this product lies in its anhydrous formula —free of water and oil— engineered to stabilize vitamin C in its most active form and prevent rapid oxidation. This humectant-rich galenic base optimizes active ingredient bioavailability, neutralising free radicals while stimulating collagen synthesis. Clinical data collected over eight weeks indicates a reduction in wrinkle visibility for 94% of users and improved firmness for 75%. By doubling the skin's natural antioxidant capacity, this serum functions as both an environmental shield and structural dermal support.
