Formulation Deep Dive

Paula's Choice 25% Vitamin C + Glutathione Clinical Serum is engineered as a high-potency, water-based brightening treatment designed to target advanced signs of photoaging and uneven skin tone. The carrier system utilizes a sophisticated emulsion base of water, dimethicone, and glycerin, supplemented by C9-12 alkane and coco-caprylate/caprate to ensure a silky, spreadable texture that facilitates the delivery of oil-soluble components. The performance core features a synergistic 25% Vitamin C blend of tetrahexyldecyl ascorbate (a stable, lipid-soluble derivative) and ascorbyl glucoside, reinforced by glutathione and ergothioneine to enhance antioxidant recycling and cellular protection. Additional skin-identical ingredients like urea, sodium PCA, and trehalose provide essential humectancy, while tocopherol (Vitamin E) and ferulic acid-rich botanical extracts like oryza sativa (rice) bran further stabilize the oxidative environment. The formula is stabilized via an acrylates/C10-30 alkyl acrylate crosspolymer network and xanthan gum, utilizing a preservation system of phenoxyethanol and ethylhexylglycerin to maintain the integrity of the complex active profile.
