The Claim
"Hyaluronic acid pulls moisture from your skin instead of adding it when the air is dry — making dry skin even worse."
This one has been making the rounds on TikTok, Reddit's r/SkincareAddiction, and beauty forums everywhere. People are reporting tight, flaky, even more dehydrated skin after using HA serums — and blaming the ingredient itself. So is this a real phenomenon, or are people just using it wrong?
The Verdict: CONFIRM — with important nuance.
Yes, this can actually happen. But it's not the hyaluronic acid's fault — it's about how and where it's used.
Here's the Science (In Plain Language)
Hyaluronic acid (HA) is a humectant. That means its job is to attract and hold water — up to 1,000 times its own weight in moisture. Sounds amazing, right? It is. But here's the catch: humectants pull water from wherever they can find it.
In a humid environment (think: bathroom after a hot shower, tropical climate, or a well-humidified room), HA draws moisture from the air and delivers it to your skin. That's the dream scenario.
In a dry environment — low humidity, cold winter air, air-conditioned offices, desert climates — there's not enough moisture in the air for HA to grab. So it does the next best thing: it pulls water from the deeper layers of your skin and brings it to the surface, where it then evaporates. The result? Your skin feels temporarily plump, then drier than before.
This is called transepidermal water loss (TEWL), and it's a real, documented phenomenon in dermatology.
So Should You Stop Using Hyaluronic Acid?
Absolutely not. You just need to use it correctly.
The fix is simple: always seal HA with an occlusive or emollient on top. This means applying a moisturizer, facial oil, or balm immediately after your HA serum — while your skin is still slightly damp — to lock that moisture in before it can escape.
Think of HA as the water-delivery truck and your moisturizer as the warehouse that keeps it from driving away.
The Molecular Weight Factor
Not all hyaluronic acid is created equal. High molecular weight HA sits on the surface of the skin and creates a plumping, film-forming effect. Low molecular weight HA penetrates deeper into the skin layers. The best formulas use a combination of both — giving you surface hydration AND deeper moisture delivery.
If your HA serum is causing dryness, it may also be a formulation issue — some cheaper serums use only one molecular weight, or include alcohol that accelerates evaporation.
The Bottom Line
Hyaluronic acid is one of the most effective hydration ingredients in skincare — but it needs a partner. In dry climates or during winter months, always follow your HA serum with a rich moisturizer or facial oil to seal in the moisture it delivers. Without that seal, you're essentially opening a window in winter and wondering why the house is cold.
