Paula's Choice

C15 Super Booster

SerumPremiumMorning only

Dark SpotsAgingDullnessSensitive skinDamaged barrier

15% L-ascorbic acid with vitamin E and ferulic acid — the classic CE Ferulic-style antioxidant trio at a slightly lower price. Small bottle is deliberate: L-AA oxidises once air-exposed, so smaller packaging keeps potency up.

The reference-standard antioxidant serum — 15% L-ascorbic acid, 1% vitamin E, 0.5% ferulic acid, formulated below pH 3.5 (the L-ascorbic acid standard from Pinnell's Duke University research). Demonstrably increases photoprotection when layered under SPF. Expensive, but what every other 'CEF dupe' is trying to be.
