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 are ranked by how many of those they match, then by price.

Are C15 Super Booster dupes really as good as the original?
A dupe matches the hero actives — the ingredients doing the measurable work — but rarely the full sensory experience. Texture, fragrance, supporting ingredients and exact concentrations differ, so treat a dupe as a value-led alternative rather than an identical copy.

"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.
