Everyone’s obsessed with hyaluronic acid. Now everyone’s terrified of it.
The rumor: if the air is dry, HA pulls water from your skin’s deeper layers. Leaves you more parched. We had to test it.
It’s the The Ordinary Hyaluronic Acid 2% + B5. Under $10. The claim that made me try it? That it’s a dehydration trap.
Texture
Water-light, slightly viscous slip.
Absorption
Sinks in under 15 seconds on damp skin.
Finish
Zero residue. Not sticky at all.

It’s not one HA, it’s three molecular weights. Low weights go deeper, high weights sit on the surface. B5 is the repair agent.
- Hyaluronic Acid (Low MW): Penetrates for long-term hydration
- Hyaluronic Acid (Mid MW): Plumps mid-layer
- Hyaluronic Acid (High MW): Surface-level moisture film
- Vitamin B5 (Panthenol): Soothes and supports barrier repair

Feels like cool water spreading. Then it’s just gone. On dry skin? It grabs and pulls — you feel that tightness instantly.
Used it in my desert-dry bedroom with a space heater. The trick: it’s not the serum. It’s your follow-up. Slap moisturizer on top within 60 seconds or you’re cooked.
My skin was softer by day 4. No miracle plumping. No dehydration — when I used it right. It’s a hydrating booster, not a solo act.
It doesn’t dehydrate you. User error does. This serum is a team player — don’t send it out alone.
