Can Hyaluronic Acid Dry Out Your Skin?
Can hyaluronic acid dry out your skin? It can feel drier used alone in dry air. What studies show, winter humidity math and the damp-skin, seal-it fix.
Hyaluronic acid does not damage skin or dry it out on its own, but a hyaluronic acid serum used alone can leave skin feeling tighter a few hours later, especially in dry winter air. Hyaluronic acid is a humectant: it holds water without sealing it in. Apply it to damp skin, then cover it with a moisturizer or occlusive.
The popular version of the warning, that hyaluronic acid “pulls water out of your face” in dry weather, mixes one real mechanism with a claim no trial has measured. Here is what the studies show, why winter makes it worse, and the routine that fixes it.
Can hyaluronic acid dry out your skin?
It can make skin feel drier when it is the last thing you put on, but it does not strip or damage the skin barrier. The dryness people describe is a timing problem: the water a hyaluronic acid serum adds to the surface evaporates within hours unless something slows it down.
Hyaluronic acid is a long sugar chain (a glycosaminoglycan) that skin makes naturally. On a label it usually appears as Sodium Hyaluronate, its salt form, or as Hydrolyzed Hyaluronic Acid, a version cut into shorter fragments. Both are humectants, meaning ingredients that attract and bind water. Glycerin, butylene glycol, urea and panthenol are humectants too.
The best direct evidence comes from a randomized study published in the International Journal of Cosmetic Science in 2026 by Maldonado López and da Silva Souza (PMC full text). They split 123 volunteers into four groups: cleanser only (the control), a hyaluronic acid serum, a moisturizing cream, and the serum followed by the cream. The serum listed 1.0% sodium hyaluronate plus hydrolyzed hyaluronic acid in a base of water, propanediol and glycerin. All measurements were taken in a climate-controlled room at 22°C (72°F) and 55% relative humidity.
At 30 minutes, the serum, the cream and the routine all raised skin hydration compared with the control. At 8 hours, only the serum-plus-cream routine was still higher. The authors put it plainly: the serum “alone did not sustain the significant skin hydration after 8 h of its application.” Both authors work for Good Molecules, the brand that makes the products tested, so treat it as a well-designed brand study rather than independent confirmation.
That result describes what most people feel. A watery serum gives an immediate plump, dewy look, and by mid-afternoon the skin feels like nothing was applied, or tighter than before because the face was also washed.
Does hyaluronic acid pull water out of your skin in dry air?
That part of the claim is a plausible mechanism, not a measured result. Humectants can draw water upward from the deeper, living layers of skin into the stratum corneum, the dead outer layer that does most of the barrier work. A 2017 review in Clinical Medicine and Research by Purnamawati and colleagues states the mechanism directly:
“Humectants can also enhance trans-epidermal water loss by increasing water absorption from dermis into epidermis.” — Purnamawati et al., Clinical Medicine and Research, 2017
Transepidermal water loss (TEWL) is the water that evaporates through the skin into the air; it is the standard measure of how well the barrier holds water. The reasoning behind the myth goes: in humid air, a humectant can pull some water from the atmosphere; in very dry air there is little to pull, so the water it binds comes from inside the skin, sits near the surface and then evaporates.
What the measurements show is narrower. In the 2026 study above, the hyaluronic acid serum did the opposite of drying: TEWL was lower than the cleanser-only control at 30 minutes and was still lower at 8 hours. That was at 55% humidity, typical of a comfortable room, not a heated apartment in January. The low-humidity version of the claim rests on mechanism alone; it has not been tested in a controlled human study comparing a hyaluronic acid serum with bare skin in dry air. So the accurate summary is:
- Supported: a humectant left on its own does not keep skin hydrated for long; a cream on top extends the effect.
- Supported: dry air dehydrates the outer skin within hours, with or without skincare.
- Mechanism only: that hyaluronic acid itself increases water loss in low humidity.
- Myth: that hyaluronic acid damages the barrier or “dries out” skin the way a harsh cleanser does.
What does low humidity do to skin?
Dry air pulls water out of the outer skin layer quickly, on its own. In a 2002 study in Skin Research and Technology, Shiseido researchers placed healthy volunteers in a low-humidity room and measured the forearm and cheek. Water content of the stratum corneum fell significantly after 3 hours and again at 6 hours, and skin replicas showed rougher surface texture and more visible fine lines (Egawa et al., 2002).
Longer exposure weakens the barrier itself. A 2016 review of the climate literature in the Journal of the European Academy of Dermatology and Venereology concluded that “low humidity and low temperatures lead to a general decrease in skin barrier function” and make skin more reactive to irritants, and that cold, dry weather raises the risk of eczema flares (Engebretsen et al., 2016).
This is why many people notice hyaluronic acid “stops working” in winter. The serum has not changed. The air around it has.
How dry is indoor air in winter?
Heated winter air is very dry. Relative humidity is the amount of water vapor in the air as a percentage of the most the air can hold at that temperature. Warm air can hold far more vapor than cold air, so when furnaces heat cold outdoor air without adding water, the relative humidity collapses.
We calculated indoor humidity with the Magnus formula for saturation vapor pressure, assuming outdoor air is heated to 70°F (21°C) with no humidifier:
| Outdoor air | Outdoor relative humidity | Indoor relative humidity at 70°F |
|---|---|---|
| 41°F (5°C) | 60% | about 21% |
| 32°F (0°C) | 50% | about 12% |
| 23°F (minus 5°C) | 70% | about 12% |
| 14°F (minus 10°C) | 70% | about 8% |
Real homes run a little higher because cooking, showers and breathing add moisture, but the direction holds. The US Environmental Protection Agency advises keeping indoor humidity “below 60 percent (ideally between 30 and 50 percent)” (EPA mold and moisture guide, checked October 2026). On a cold day without a humidifier, most heated rooms sit well under the bottom of that range. A small hygrometer tells you which row of the table you are living in.
Does molecular weight change whether hyaluronic acid dries skin?
Molecular weight changes where hyaluronic acid goes and what it does, not whether it needs to be sealed. Molecular weight is measured in kilodaltons (kDa); higher numbers mean longer chains.
- Penetration: in a 2016 Raman spectroscopy study of human skin sections, hyaluronic acid of 20 to 300 kDa passed through the stratum corneum, while 1,000 to 1,400 kDa hyaluronic acid stayed out (Essendoubi et al., 2016). High-weight hyaluronic acid forms a water-holding film on the surface; lower weights move into the outer layers.
- Hydration and wrinkles: in a 2011 trial in the Journal of Drugs in Dermatology, 76 women aged 30 to 60 applied 0.1% hyaluronic acid cream of 50, 130, 300, 800 or 2,000 kDa around one eye twice daily for 60 days, with a plain vehicle cream around the other eye. Every molecular weight improved hydration and elasticity compared with the vehicle. Only the 130 and 50 kDa creams reduced wrinkle depth (Pavicic et al., 2011).
Note that every product in the Pavicic trial was a cream, not a watery serum, which fits the rest of the evidence: hyaluronic acid delivered in a base that also slows evaporation reliably improved hydration.
Decoding a label: the INCI name does not reveal molecular weight. “Sodium Hyaluronate” can be any size, and the weight appears only if the brand discloses it. “Hydrolyzed Hyaluronic Acid” signals smaller fragments. “Sodium Hyaluronate Crosspolymer” is a cross-linked network that sits on the surface. “Multi-weight” serums such as the Anua PDRN Hyaluronic Capsule 100 Serum, which lists eight hyaluronic acid forms, combine several of these. None of them changes the basic rule that a humectant needs something on top.
How do you use hyaluronic acid without drying out?
Put it on damp skin and seal it in within a minute or two. The order matters more than the brand.
- Apply to damp skin. The American Academy of Dermatology advises: “Apply your moisturizer when your skin is still damp after taking a shower or bath, after washing your hands, and when your skin feels dry” (AAD dry skin tips, updated January 2, 2026). Pat the face with a towel so it is damp rather than dripping, or mist it before the serum.
- Use a thin layer. A few drops spread over the face; more serum does not add more hold, and a thick humectant layer can feel sticky.
- Seal with a moisturizer. An occlusive is an ingredient that forms a film that slows evaporation (petrolatum, mineral oil, dimethicone, lanolin). An emollient is an oil or lipid that smooths and softens the surface (squalane, shea butter, esters). A good cream combines humectants, emollients and some occlusion. The AAD notes that “ointments and creams add more moisture to skin and are more effective than lotions.”
- Add an occlusive where skin is dry. The 2017 Purnamawati review reports that petrolatum at 5% or more can cut TEWL by more than 98%, while lanolin, mineral oil and silicones reduce it by 20% to 30%. A thin layer of petrolatum over dry patches at night is the most efficient upgrade.
- Fix the air. The AAD recommends running a humidifier in the bedroom while you sleep.
Barrier creams are the natural partner for a hyaluronic acid serum. The AESTURA Atobarrier 365 Cream is an example of the design: glycerin and butylene glycol as humectants, squalane and esters as emollients, dimethicone for film, and ceramide-type lipids, cholesterol and free fatty acids for the barrier.
Glycerin is worth a note here. It is also a humectant, yet a review in the British Journal of Dermatology describes its hydrating effect as “critical in skin conditions aggravated by dry and cold environmental conditions, e.g. winter xerosis” (Fluhr et al., 2008). If humectants simply dried skin in winter, glycerin would fail too. What both need is a formula or a routine that keeps the water in.
Why is my skin dry even though I moisturize?
If your concern is burning rather than a dry finish, our guide to why moisturizer stings explains what to change and when to seek care.
Usually because the routine adds water but not enough seal, or because something else in the routine is removing water faster than the moisturizer can replace it. Use this table to match the clue to the cause.
| What you notice | Likely cause | Fix | Evidence basis |
|---|---|---|---|
| Dewy right after the serum, tight by afternoon | Humectant serum with nothing on top | Follow the serum with a cream within a minute or two | Randomized 2026 study, n=123: only serum plus cream stayed above control at 8 hours |
| Tightness that starts in late fall | Heated indoor air under 30% humidity | Bedroom humidifier; richer cream; ointment on dry patches | Egawa 2002; Engebretsen 2016 review; EPA 30% to 50% guidance |
| Skin feels stripped right after washing | Long, hot showers or a harsh cleanser | 5 to 10 minute warm showers; gentle cleanser; moisturize while damp | AAD guidance |
| Lotion absorbs in seconds and dryness returns | Lotion too light for the season | Switch to a cream; add petrolatum at night | AAD: creams and ointments more effective than lotions |
| Dryness, flaking and stinging on retinoid or acid nights | Irritation from actives | Fewer active nights; buffer with moisturizer; one new active at a time | Engebretsen 2016: dry air makes skin more reactive to irritants |
| Dry, peeling lips despite hydrating products | Watery products or lip-licking evaporating | Petrolatum or ceramide balm several times a day and before bed | AAD lip guidance |
Two habits make winter dryness worse in ways people underestimate: exfoliating more often to remove flakes, which thins the barrier further, and skipping moisturizer in the morning because the skin feels fine after the night cream. If you use actives, our guide to layering niacinamide and azelaic acid covers how to introduce them one at a time. And winter skincare is also a sunscreen question; see whether you need sunscreen in winter.
If dryness comes with intense itch, cracking, bleeding or red, scaly patches that do not settle with a richer routine, a board-certified dermatologist can check for eczema or another condition.
Can hyaluronic acid dry out your lips?
A watery hyaluronic acid product alone can leave lips feeling drier, for the same reason licking them does. The American Academy of Dermatology explains that licking dry lips “can worsen the problem. As saliva evaporates, your lips become drier.” Lips have a thin outer layer and no oil glands, so water added without a seal leaves quickly.
The AAD’s list of lip balm ingredients to look for includes petrolatum, ceramides, dimethicone, mineral oil, shea butter and castor seed oil, and for very dry lips it suggests “a thick ointment, such as white petroleum jelly” (AAD chapped lips tips). The same page lists ingredients to avoid, including camphor, menthol, fragrance, flavorings such as mint and cinnamon, and salicylic acid. A hyaluronic acid lip product is fine if it is a balm or ointment rather than a gel or serum.

A winter routine that keeps hyaluronic acid working
| Step | Morning | Night |
|---|---|---|
| Cleanse | Water rinse or a gentle cleanser | Gentle cleanser, lukewarm water |
| While damp | Hyaluronic acid serum, a few drops | Hyaluronic acid serum, a few drops |
| Treatment | Optional antioxidant or niacinamide serum | Retinoid or acid on scheduled nights only |
| Seal | Cream moisturizer | Richer barrier cream |
| Extra seal | None, or a balm on dry spots | Thin petrolatum on dry patches and lips |
| Protect | Broad-spectrum SPF 30 or higher | Bedroom humidifier aiming for 30% to 50% |
If a serum still feels drying with this routine, try a cream that already contains hyaluronic acid instead of a separate serum, which builds the seal into the same step.

Frequently asked questions
Can hyaluronic acid dry out your skin?
It can leave skin feeling tight or drier a few hours later when a watery serum is used alone in dry air, because hyaluronic acid holds water but does not seal it in. In a 2026 randomized study of 123 volunteers, a hyaluronic acid serum raised hydration at 30 minutes but only the serum-plus-cream routine kept hydration higher at 8 hours.
Does hyaluronic acid pull water out of your skin in low humidity?
That is a mechanism, not a measured result. Humectants can draw water from deeper skin layers into the outer layer, but no controlled study has shown a hyaluronic acid serum increasing water loss in dry air. The practical fix is the same either way: apply it to damp skin and cover it with a moisturizer.
Can hyaluronic acid dry out your lips?
A watery hyaluronic acid product on bare lips behaves like licking them: the water evaporates and lips can feel drier. The American Academy of Dermatology recommends lip balms with petrolatum, ceramides, dimethicone or shea butter, and thick white petroleum jelly for very dry lips.
Should I use hyaluronic acid in winter?
Yes, as long as it is sealed. Heated indoor air in winter can fall to roughly 10% to 20% relative humidity, well below the 30% to 50% the EPA recommends, so pair the serum with a cream, add an ointment on dry patches, and run a humidifier at night.
Which molecular weight of hyaluronic acid is best for dry skin?
In a 60-day trial of 76 women, 0.1% hyaluronic acid at every molecular weight tested, from 50 to 2,000 kDa, improved hydration versus a plain cream. Only the 50 and 130 kDa versions reduced wrinkle depth. For dryness, the occlusive you put on top matters more than the weight.
