Are Retinol B3 Serum 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.
