Common questions
Is the Neutrogena Hydro Boost Water Gel a real dupe?
It overlaps on hero actives with 3 same-category products in our catalogue — most closely the Eucerin Hyaluron-Filler Night Cream at 99% active overlap. "Dupe" here means shared active ingredients, not an identical formula.
Does a higher overlap mean it is better?
No — overlap only measures shared hero actives. Base, supporting actives, texture and price still differ, so use the side-by-side compare for the full picture.
Educational information only — not medical advice. Overlap reflects shared hero actives, not clinical equivalence.
