Hyaluronic Acid 2% + B5 (with Ceramides)
A lightweight hydration serum with multiple forms of hyaluronic acid, panthenol, and barrier-supportive lipids.
A strong hydrating serum for dehydrated or tight-feeling skin that wants plumping hydration without a heavy finish. The multi-HA + B5 + lipid formula is genuinely more complete than a basic HA serum.
Multi-molecular HA means it hydrates at different skin depths. Adding panthenol (B5) and barrier lipids (phospholipids, sphingolipids) makes this more barrier-supportive than a standard HA serum — and at The Ordinary's price point, that combination is exceptional value.
After cleansing and toning, before moisturizer. Apply to damp skin. Works morning and evening.
Anyone whose skin feels tight, dull, or dehydrated — especially in cold weather or dry climates. Also great during active phases (retinol, acids) where extra hydration support helps.
If your moisturizer is already rich in HA and barrier lipids — the stack may feel redundant. Not harmful, but possibly unnecessary layering.
This is one of the safest products to continue during a skin flare-up. It's hydrating and supportive without any active ingredients that could cause irritation.
- A gentle cleanser
- Any moisturizer layered on top to seal in the HA
- Mineral SPF in the morning
Best For
- Dehydration
- Tight skin
- Dullness from dryness
- Barrier support
- Layering in simple routines
How to Use
Apply after cleansing and before moisturizer in the morning and/or evening. Apply to damp skin for best results.

About This Product
The Ordinary Hyaluronic Acid 2% + B5 with Ceramides is an updated version of their original HA serum, now including panthenol (the B5) for barrier support and phospholipids and sphingolipids for a more complete lipid profile. The formula includes sodium hyaluronate (standard HA), hydrolyzed hyaluronic acid (deeper-penetrating smaller molecules), and sodium hyaluronate crosspolymer (a cross-linked version that stays on the surface longer). These three forms of HA work at different skin depths for more comprehensive hydration.
