Quick answer: the closest dupe for the Paula's Choice C15 Super Booster is the Naturium Vitamin C Complex Serum — 99% active overlap, sharing Ferulic Acid, Vitamin C, Vitamin E. A much lower price for a comparable active core; you trade the base, supporting actives and texture, not the headline ingredients.
The contextWhy look for a C15 Super Booster dupe?
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.
A good dupe isn't about a matching label — it's about matching the hero actives, the ingredients carrying the real work. For this serum that means Vitamin C, Vitamin E, Ferulic Acid. The alternatives below share that profile; where they differ is in texture, supporting ingredients and finish.

Are C15 Super Booster dupes really as good as the original?

How does Skin Stacker choose C15 Super Booster dupes?
We match products in the same category (serum) that share hero actives (Vitamin C, Vitamin E, Ferulic Acid), then rank by overlap and price. Matches are based on published INCI lists, not lab assays.
Compare them yourself
Skin Stacker is independent and receives no payment from any brand. "Dupe" matches are based on publicly disclosed INCI lists and shared hero actives — not on side-by-side lab testing. A shared active profile does not guarantee an identical experience: texture, fragrance, supporting ingredients and concentrations all differ. Formulations change — always re-check the current label before buying.
