Hydro Boost Ultra Hydrating Serum — Reddit Reviews
by Neutrogena
Updated September 30, 2026
Hyaluronic-acid serum for quick hydration and less tight-feeling skin; sometimes underwhelming.
What the community says
A hyaluronic-acid serum built around glycerin, sodium hyaluronate, and a pile of humectants plus dimethicone for slip. It suits dehydrated skin and people layering it before moisturizer; some users say it does basically nothing, so YMMV.
