Hyaluronic Acid Can Actually Dehydrate Your Skin (Here's When)
The internet's favorite hydrator has a counterintuitive dark side — in dry air, a humectant with nothing to seal it can pull water out of your skin instead of into it.
Good choice for Dehydration
What Makes This Different
It's a versatile overnight or wash-off hydrating gel mask with a comprehensive nine-form HA complex, a working niacinamide dose for glow, and a cica-and-ceramide soothing base — a loaded hydration-and-glow mask cooled with alpine glacier water.

Hydrating Sleeping Mask

A loaded, versatile hydrating gel mask — usable overnight or as a wash-off — built on a comprehensive nine-form hyaluronic acid complex with working-level niacinamide and a cica-and-ceramide soothing base, cooled with alpine glacier water. It genuinely plumps, dews and lightly brightens at a fair price; tea tree oil and added fragrance are the main caveats for sensitive skin.

As a clinic-tied line, Wonjin Effect carries a moderate review base and a transparent INCI, so, clinic-tied positioning and a moderate review base, and the mask's INCI is transparent, so this medium-confidence rating rests on a clear read: a nine-form hyaluronic complex with niacinamide at a stated 1.6-2.3% and a cica-and-ceramide base. The hydration and glow benefits are well-supported; the clearest takeaways are that the glacier water is sensory marketing and the tea-tree-and-fragrance content is the main tolerability factor.

Review
Full Review
Wonjin Effect's Water Glow Mask sells a cooling, alpine 'glow,' but the reason to buy it is more substantive than the marketing: under the glacier-water story is a genuinely loaded hydration-and-niacinamide gel that works as either an overnight sleeping mask or a quick wash-off, and does its hydrating-and-brightening job well.
The hydration core is comprehensive. The mask carries a nine-form hyaluronic acid complex — sodium hyaluronate, hyaluronic acid, hydrolyzed and acetylated forms, crosspolymer, silanol and more — that hydrates at many depths, flooding the skin overnight (or during a wash-off soak) to leave it plumped and dewy. That breadth of HA is more than most masks bother with, and it's the genuine basis of the 'water glow.'
What lifts it above a plain hydrator is niacinamide, listed fifth at a stated 1.6-2.3% — a real working level. Niacinamide brightens, evens tone, supports the barrier and helps with oil, so with regular use the mask delivers a genuine 'glow' benefit beyond a per-use plumping. Backing it is a sensible soothing-and-barrier base: centella with madecassoside, houttuynia cordata, ceramide NP, panthenol and allantoin. That cica-and-ceramide cast makes the mask calming as well as hydrating, suiting it to overnight use.
The glacier water and cooling plant extracts are the on-brand flourish — pleasant and refreshing, but essentially mineralized water; the hydration, glow and soothing come from the HA, niacinamide and cica, not the alpine story. The versatility is a genuine plus: leave it on overnight as a sleeping mask for deep hydration, or use it as a 10-15 minute wash-off for a quick boost.
The caveats are the tea tree oil and fragrance. The mask contains both, which gives it a fresh scent but adds irritation potential — so sensitive, reactive, or rosacea-prone skin should patch test or choose a fragrance-free hydrating mask. The tea tree oil also means it isn't fungal-acne safe, and the hydrolyzed collagen means it isn't a vegan formula. For normal-to-oily skin, none of these are dealbreakers.
The brand and data picture is reasonable: Wonjin Effect's clinic-tied positioning and a fair review base, blended with a transparent INCI that confirms the loaded hydration-and-niacinamide formula.
Value is good. At around twenty-one dollars for 100ml used regularly, a nine-form-HA-and-niacinamide gel mask that doubles as an overnight or wash-off treatment is a fair deal, lasting two to three months.
The clever thing about this mask is its versatility, and it's worth using it deliberately rather than as an afterthought. As a leave-on sleeping mask, applied as the last step at night, it forms a hydrating layer that works while you sleep and leaves skin plumped and dewy by morning — ideal for dry or dehydrated skin, or after a day of sun, wind, or travel. As a 10-15 minute wash-off mask, it's a quick mid-routine hydration-and-glow boost. Either way, the genuine engine is the nine-form hyaluronic acid for plumping and the niacinamide at a working 1.6-2.3% for tone-evening and a real, cumulative 'glow' over weeks — that niacinamide level is what lifts this above a basic hydration jar. The cica-and-ceramide base (centella, madecassoside, houttuynia, ceramide NP) keeps it soothing as well as hydrating, which suits overnight use. The 'glacier water' is the marketing flourish: pleasant and cooling, but essentially mineralized water, so don't let the alpine story drive the purchase. The main caveats are the tea tree oil and added fragrance, which give it a fresh scent but add irritation potential, making it a poor fit for sensitive or rosacea-prone skin, and the tea tree oil means it isn't fungal-acne safe. For normal-to-oily skin that tolerates the scent, though, a versatile, loaded hydration-and-glow mask at this price — usable two ways — is a genuinely useful, well-built addition to a routine, as long as the niacinamide and HA, not the glacier water, are what you're buying it for.
Its dual format also makes it good value in practice: one jar covers both an intensive overnight treatment and a quick wash-off boost, so it flexes to whatever your skin needs that night. For fragrance-tolerant skin, that versatility plus the genuine niacinamide-and-HA payload is what justifies keeping it in rotation.
For oily and combination skin in particular, the lightweight water-gel texture and niacinamide make it a rare overnight mask that hydrates and brightens without feeling heavy or greasy by morning — a genuine gap it fills well, provided the tea-tree-and-fragrance scent doesn't bother you.
The bottom line: a genuinely loaded, versatile hydrating-and-glow gel mask that delivers more than its glacier-water marketing suggests — nine-form HA for plumping, working niacinamide for glow, and cica-and-ceramide for soothing. For normal, dry, combination, or oily skin wanting a cooling overnight or wash-off hydration boost, and not bothered by a tea-tree-and-fragrance scent, it's an effective, affordable, flexible pick. Sensitive or fungal-acne-prone skin should choose a fragrance-free, tea-tree-free hydrating mask instead.

Evidence
Science & Expert Perspective
The Science
The mask is a genuinely loaded hydration-and-glow formula. A nine-form hyaluronic acid complex (sodium hyaluronate, hyaluronic acid, hydrolyzed and acetylated forms, crosspolymer, dimethylsilanol hyaluronate, hydroxypropyltrimonium hyaluronate) provides multi-depth humectant hydration, the basis of the plumped, dewy 'water glow.' Niacinamide at a stated 1.6-2.3% (fifth on the list) is a genuine working level, well-evidenced for tone-evening, barrier support and sebum regulation — the real 'glow' over time. Centella asiatica with madecassoside, Houttuynia cordata and ceramide NP, plus panthenol and allantoin, provide soothing and barrier support. Glacier water and cooling botanicals contribute a sensory, mildly refreshing effect rather than a functional active. The tolerability considerations are tea tree (Melaleuca) oil and added fragrance, both recognized irritants, and the tea tree oil renders the formula not fungal-acne safe; hydrolyzed collagen makes it non-vegan. The evidence-aligned conclusion: an effective, versatile hydrating-and-brightening gel mask whose nine-form HA and working niacinamide do genuine work, with tea tree and fragrance the main caveats.
Dermatologist Perspective
As an overnight or wash-off hydrating mask, this is well-built: a broad hyaluronic acid complex for hydration, niacinamide at a functional level for tone and barrier, and a cica-and-ceramide base for soothing — a sensible combination for plumping, calming and gradually brightening normal-to-oily skin. The glacier water is best regarded as sensory. The relevant reservations are the tea tree oil and added fragrance, both potential irritants that make the mask less suitable for sensitive, reactive, or rosacea-prone skin, and the tea tree oil also makes it unsuitable for fungal-acne-prone individuals. The versatility (overnight or wash-off) is a practical advantage. For normal-to-oily skin seeking a hydrating-and-glow mask and tolerant of the scent, it is a reasonable, evidence-aligned choice; sensitive skin would do better with a fragrance-free hydrating mask.
Guidance
Usage & Recommendations
How to Use
At night, after your routine, apply a layer as the last step and leave it on as a sleeping mask, rinsing in the morning — or use it as a 10-15 minute wash-off mask for a quick boost. Use regularly for the niacinamide glow to build, and apply sunscreen in the morning as usual. Because it contains tea tree oil and fragrance, patch test first if your skin is sensitive, and fungal-acne-prone skin should note the tea tree oil.
Value Assessment
At around $21.06 for 100ml used regularly, this is good value: a nine-form-HA-and-niacinamide gel mask that doubles as an overnight sleeping mask or a wash-off treatment offers genuine versatility and a loaded hydration-and-glow formula for the price, lasting two to three months. You're paying for substantive actives — broad HA plus working niacinamide and cica — rather than the glacier-water marketing. The value holds for fragrance-tolerant, normal-to-oily skin; sensitive or fungal-acne-prone skin would get less from it given the tea tree and fragrance, and should spend on a fragrance-free alternative.
Who Should Buy
It earns a spot if you have normal, dry, combination, or oily skin and want a versatile, loaded hydrating-and-glow gel mask — usable overnight or as a wash-off — with a comprehensive HA complex, working niacinamide and cica soothing. Great for a cooling hydration boost and gradual brightening for fragrance-tolerant skin.
Who Should Skip
Hold off if your skin is sensitive, reactive, or rosacea-prone (tea tree oil and fragrance), if you're fungal-acne-prone (tea tree oil), or if you want a vegan formula (it contains collagen). A fragrance-free, tea-tree-free hydrating mask would suit those needs better.

Myth vs. Reality
Common Myths
Myth
Glacier water is what makes this mask work.
Reality
Glacier water is a pleasant, on-brand marketing touch with a cooling feel, but it's essentially mineralized water — the genuine work comes from the nine-form hyaluronic acid (hydration), niacinamide (glow and barrier) and the cica-and-ceramide soothing base. Buy it for those, not the alpine-water story.
FAQ
Frequently Asked Questions
Is it a sleeping mask or a wash-off mask?
Both — it's a versatile water-gel you can leave on overnight as a sleeping mask or use as a 10-15 minute wash-off mask. Either way it delivers a nine-form hyaluronic hydration boost plus niacinamide and cica soothing, leaving skin plumped and dewy.
What actually does the 'glow'?
Niacinamide at a working 1.6-2.3% brightens and evens tone over time, while the nine-form hyaluronic acid complex plumps and dews the skin for an immediate radiant look. The cooling glacier water adds a refreshing feel but is sensory; the niacinamide and HA are the real workers.
Is the Water Glow Mask safe for sensitive skin?
Use caution. It's hydrating and has soothing cica and ceramide, but it contains tea tree oil and added fragrance, both of which can bother sensitive or reactive skin. Those skin types should patch test or choose a fragrance-free hydrating mask; most normal-to-oily skin tolerates it well.
Can oily skin use it?
Yes — it's a lightweight water-gel with niacinamide (good for oil and pores), so oily and combination skin often enjoy it as a cooling overnight hydrator. Note it isn't fungal-acne safe due to the tea tree oil, so malassezia-prone skin should be aware.
Is it fragrance-free or vegan?
Neither — it contains tea tree oil and added fragrance, and it includes hydrolyzed collagen (animal-derived), so it isn't vegan. It's otherwise a lightweight, mostly oil-free gel.
