Why We Chose It
Luxury vitamin-C options flood the market, yet very few balance potency, stability, and skin-soothing extras. After screening 37 brightening serums, our chemist-panel short-listed C15 for its clinically balanced 15 % l-ascorbic acid + vitamin E + ferulic acid trio—the same antioxidant cocktail derms love for post-procedure glow ups.
Ingredient Intelligence
| Star Complex | Skin Benefit | Concentration* |
|---|---|---|
| L-Ascorbic Acid 15 % | Brightens, firms, shields from pollution | 15 % |
| Vitamin E (Tocopherol) | Lipid-rich antioxidant, calms irritation | 1 % |
| Ferulic Acid | Stabilises vitamin C, doubles UV defence | 0.5 % |
*Estimated from Paula’s Choice patent filing & INCI list.
Think of ferulic acid as a bodyguard—it keeps the fickle vitamin C steady and doubles its free-radical takedown power.
