Does Hyaluronic Acid Serum Actually Dehydrate Your Skin?

Myth Busted

We tested the viral claim that this cult serum can suck moisture *out* of your skin instead of adding it.

Expert Analysis · Honest Reviews · Real Results

1.💧The Backwards Serum

So the internet says this serum can *steal* moisture from your face. Wild, right? I had to test it.

The fear is real if you live in a dry climate — the serum could pull water from your skin instead of the air. A total hydration heist.

2.❓The Cult Drop

It’s The Ordinary’s Hyaluronic Acid 2% + B5. Under $10. The claim that made it viral? Plumps skin like nothing else. The fear? That it backfires.

Slightly viscous, like thin syrup.

Absolutely nothing. Zero fragrance.

Glass dropper — feels clinical, not luxurious.

3.🔍What’s Actually In It

It’s not just one type of hyaluronic acid. They use a cocktail of weights to penetrate different layers. The B5 is there for repair, not hydration.

4.📊The Feel Test

Applies slick. Absorbs in under 20 seconds — leaves a faint, sticky film. Not dewy. Not dry. Just… there.

Week 2, my skin felt softer. But the real surprise? My t-zone got shinier. Not plumped, just oilier. My dry cheeks loved it, though.

💡

One Thing: Apply to damp skin. Always. I mist my face first — it gives the HA water to grab onto immediately.

5.💡Who It’s Really For

Fine lines looked a bit softer by week 3. No miracle plumping. Hydration? Yes. But only if you apply it correctly.

✅

Buy if

Your skin is normal to dry and you’ll commit to applying it on damp skin.

⏭️

Skip if

You’re very oily or live in a desert-dry environment without a humidifier.

💰

Worth it?

For the price, it’s a no-brainer test. But it’s a hydrating helper, not a solo act.

6.✅The Myth, Busted

It won’t dehydrate you if you use it right. But it’s not the magic juice TikTok says it is. A solid, boring workhorse.

7.5/10

Effective, but needs a specific technique.

Where to Buy: Direct from The Ordinary or Sephora. Buy the 30ml first to see if your skin agrees with it.
