Everyone’s freaking out that hyaluronic acid can suck moisture *out* of your skin. So I tested the theory on the most popular one.
The fear is real if you live in a dry climate — the serum could pull water from your skin instead of the air. A legit skincare plot twist.
It’s The Ordinary Hyaluronic Acid 2% + B5. $8. I bought it because the internet said it was a desert — or a sponge.
Texture
Slightly thicker than water — has a tiny bit of slip.
Scent
None. Zero. It smells like the inside of a lab beaker.
Packaging
The dropper is fine, but you will absolutely knock the bottle over at least once.

It’s not just one type of HA. They use a cocktail of weights to penetrate different layers. The B5 is there for repair, not hydration.
- Low-Molecular Weight HA: Can go deeper into skin
- High-Molecular Weight HA: Sits on surface to plump
- Crosspolymer HA: A moisture-binding network
- Vitamin B5 (Panthenol): Soothes and supports barrier

Applies like a slick gel. Absorbs in 15 seconds flat — leaves a faint, sticky film for a minute. Not a dealbreaker.
Used it in dry, winter air. The trick? My skin felt tighter if I didn’t seal it in. The myth has a kernel of truth.

My skin was plumper. Lines looked softer. But it didn’t magically solve dehydration — that’s a whole routine thing.
It doesn’t dehydrate you — user error does. A brilliant, basic hydrator if you follow the rules.
