Pure L-Ascorbic Acid is notorious for rapid oxidative degradation. Combining it with lipid-soluble Vitamin E and plant-derived Ferulic acid creates a self-regenerating antioxidant network.
1. Duke Antioxidant Synergy Formula
- Low pH Requirement: Formulating at pH 2.8–3.2 neutralizes the ionic charge of L-ascorbic acid, enabling rapid stratum corneum lipid penetration.
- Eightfold Photoprotection: The synergistic trio (15% C, 1% E, 0.5% Ferulic) delivers an 8x boost in biological defense against solar erythema and free radicals.
- Airless Opaque Delivery: Amber glass and airless pump canisters prevent photo-oxidation and preserve formula potency for 6+ months.
