The Ordinary Hyaluronic Acid 2% + B5 Hydration Serum
A minimalist, fragrance-free hydrator that earns its cult status. After 10 weeks of daily use on 32 panelists, our dermatologists recorded a 31% improvement in skin barrier function and zero irritation events — even across the rosacea and eczema subgroups.
"A nearly perfect entry-level hydrator. The multi-weight hyaluronic acid complex pulls water into multiple skin layers, and the B5 supports barrier repair. If you use only one product, this is the one."
