Is the Neutrogena Hydro Boost Water Gel a real dupe?
It shares hero actives with 3 same-category products in our catalogue, most closely the Eucerin Hyaluron-Filler Night Cream (matching 1 of 1 of its hero actives). "Dupe" here means shared key ingredients, not an identical formula.
Does matching more hero actives make it better?
No. The match count only shows how many hero actives are shared. The base, supporting ingredients, texture and price still differ, so use the side-by-side comparison for the full picture.
Educational information only — not medical advice. Overlap reflects shared hero actives, not clinical equivalence.
