Everyone loves this serum. And half of them are using it wrong.
Hyaluronic acid is a moisture magnet — applied to dry skin, it pulls water from your skin out into the air. You’re dehydrating yourself.
It’s The Ordinary Hyaluronic Acid 2% + B5. Under $10. The claim is simple hydration. I tried it because the price made me suspicious.
The Texture
Slightly viscous — like a thin, slippery gel.
The Dry-Down
Absorbs in 10 seconds on damp skin. Sticky on dry.
The Feel
Zero residue. Your skin just feels…quenched.

It’s not one HA, it’s four molecular weights. Low weights sink deeper, high weights plump the surface. The B5 is there to soothe any potential tightness.
- Hyaluronic Acid: Binds up to 1000x its weight in water
- Sodium Hyaluronate: A smaller, penetrating form
- Sodium Hyaluronate Crosspolymer: A film-forming, surface-plumping form
- Vitamin B5: Supports skin barrier repair
Apply to a freshly misted or patted-damp face. It glides — a cool, slick slip. You feel it grab onto that water instantly.
By week two, my morning foundation stopped clinging to dry patches I didn’t even know I had. The surprise? It works better in humid bathrooms.
My skin looks more even, less parched. It didn’t erase fine lines, but they’re less pronounced when skin is full of water. Zero breakouts.
It’s a brilliant, cheap hydrator — but only if you follow the damp skin rule. This is a lesson in technique, packaged in a dropper bottle.
