Formulation Deep Dive

Paula's Choice C15 Super Booster for Brightening Dullness & Uneven Tone is engineered as a high-potency, water-based brightening serum designed for rapid antioxidant delivery and skin-tone correction. The carrier system utilizes a low-pH aqueous base combined with glycerin and ethoxydiglycol to enhance the penetration of polar actives while ensuring a lightweight, non-viscous skin feel. The formulation’s performance is driven by a synergistic antioxidant network of 15% Ascorbic Acid (Vitamin C), Ferulic Acid, and Tocopherol (Vitamin E), which work in tandem to neutralize free radicals and suppress melanin synthesis. This is further supported by the inclusion of Tridecapeptide-1 and Palmitoyl Tripeptide-5 for structural remodeling, alongside Ergothioneine and Sodium Hyaluronate for enhanced cellular protection and hydration. The sensitive L-ascorbic acid is stabilized through a combination of Bisabolol and Sodium Gluconate, while the structural integrity of the liquid is maintained by Polyacrylate Crosspolymer-6 and a preservation system featuring Phenoxyethanol and 1,2-Hexanediol.
