Most sleeping packs in this price range use a water-glycerin base with a few extract decorations. This one uses 40.9% centella leaf water as its hydration phase and discloses exact ppm concentrations for the hyaluronic acid complex — the kind of transparency that's almost unheard of in K-beauty mass-market products.
A genuinely serious centella sleeping pack that discloses its active concentrations with unusual transparency — 40.9% centella leaf water as the hydration base and 1.44% total hyaluronic acid, which is higher than most competitors dare to disclose. Lightweight, calming, and fairly priced for 100ml of overnight treatment.
Note: This sleeping pack has moderate review volume and has been on the market for about two years. Our assessment reflects the available feedback and ingredient analysis; we'll revisit as more long-term data accumulates.

Most skincare INCI lists are exercises in plausible deniability. A brand lists its hero ingredient somewhere in the middle of the list, doesn't disclose concentration, and hopes you assume it's dosed usefully. The SKIN1004 Hyalu-Cica Sleeping Pack does something different — and the difference is worth leading with. On its INCI list, you'll find exact ppm values printed next to the hero ingredients: centella asiatica leaf water at 408,864 ppm (that's 40.9% of the formula), sodium hyaluronate at 4,813 ppm, hydrolyzed hyaluronic acid at 4,813 ppm, and hyaluronic acid at 4,813 ppm. That kind of disclosure is effectively nonexistent in the mass-market K-beauty category. It forces the brand to actually dose the actives usefully, because if they didn't, the numbers would embarrass them. Take SKIN1004 at their word on this one: the concentrations are real, and they're high.
What you get in practice is a lightweight gel-cream sleeping pack where the hydration phase isn't water — it's centella leaf water. The full centella active profile (madecassoside, asiaticoside, and the two acids) comes along for the ride as a built-in feature of that leaf water rather than as a spiked addition. On top of that base sits the triple HA complex at genuinely substantial dosing — 0.48% each for a combined 1.44%, well above the fraction-of-a-percent window where HA becomes a marketing prop. The three molecular weights are the point: the smallest fragments hydrate deeper in the stratum corneum, the largest sit near the surface and hold water there, and layering them is how you get hydration that persists through a full sleep cycle rather than evaporating by midnight. Then you get a sensible supporting cast: niacinamide for barrier lipid support, panthenol and polyglutamic acid for humectant reinforcement, a small amount of ceramide NP slotted alongside hydrogenated lecithin to contribute to overnight barrier repair, and melatonin included for its antioxidant story rather than any sedation claim. To be very clear on that last one, since it comes up constantly: topical melatonin at cosmetic levels is there to mop up the reactive oxygen species your skin accumulated during the day. It will not make you drowsy, and it is not in the bloodstream in any meaningful quantity.
The ingredient list also has a substantial tail of traditional Korean botanical extracts — artemisia, gardenia, larch, oak, rhubarb, corydalis, coptis, and several others — branded as a nighttime recovery complex. This is where the formula gets more complicated than a pure minimalist cream, and it's where the main trade-off lives. Those extracts are dosed at trace levels and function as much for brand storytelling as for active effect, but they do expand the surface area for potential sensitivities on extremely reactive skin. For most users this is a non-issue; for someone with a history of reactions to complex botanical blends, a patch test is sensible. It is worth noting that despite that tail, the formula is fragrance-free and alcohol-free, and reactive-skin users report it well — the concern is theoretical more often than it is realized.
The texture is the other thing that makes this sleeping pack easy to recommend. It's a thin gel-cream rather than a heavy sleeping mask — it spreads across the face cleanly, absorbs within a few minutes, and leaves behind enough of a hydrating layer to work overnight without coating your pillowcase. Polyglutamic acid deserves quiet credit here: it forms a flexible film that keeps the humectants from evaporating off the skin, which is exactly what a sleeping pack needs to do and exactly what most of them fail at. That's a balance many sleeping packs get wrong, either by being too rich (your silk pillowcase becomes a secondary mask) or too thin (the hydration is gone by 3 a.m.). This one threads the needle, and it's why it works as a nightly moisturizer substitute for normal to combination skin rather than purely as an occasional treatment. And no, you don't rinse it off in the morning — it is a leave-on final step, not a mask you wear for twenty minutes. You cleanse as usual when you wake and carry on.
On the calming front, the centella dosing genuinely shows up. Morning skin after a sleeping pack night looks visibly less flushed, dehydration lines around the eyes are softened, and there's a pronounced comfort improvement if your evening routine included anything irritating — retinol, acids, a long hot shower, a winter wind. This is where the combination of high centella and meaningful HA really pays off: you're getting both a barrier support layer and a redness-reduction layer in the same overnight product. That first-morning effect is real but it isn't the whole story; the barrier improvements accumulate over a week or two, and the fuller benefit — skin that simply holds its own water better — lands somewhere around the six-week mark of using it three or four nights a week. Post-procedure skin and winter-flayed skin are where it earns its keep most obviously.
The real limitations are modest. The jar packaging, while branded attractively, is less hygienic than an airless pump — use clean fingers or a spatula, and don't double-dip. The 100ml size is generous but the jar lid doesn't seal as tightly as some users would like, so store it upright. And while this is a solid standalone moisturizer for most skin types, it's not rich enough for severely dry skin in cold weather on its own; in that case, layer a richer cream or facial oil underneath and use this as the hydration-and-calming cap. Anyone managing fungal acne should note the olive-derived emulsifiers and triglycerides, which don't clear that particular bar. None of these are deal-breakers, but they're worth noting, and the near-1,800 reviews averaging 4.5 land in exactly the same places — people praise the morning comfort and the absence of overnight stickiness, and grumble about the jar and the length of the extract list.
On value, this sits in the middle of K-beauty sleeping pack pricing and earns its place. A 100ml jar covers two to three months of three-or-four-night weeks, and a smaller 30ml size exists if you'd rather test the botanical tail on your own face before committing. You're paying more than a generic drugstore overnight mask, but the disclosed concentrations put it in a different category entirely — this isn't a hydration mask with centella marketing, it's a centella mask with real hydration. For anyone whose skin responds well to centella and who wants a reliable, fragrance-free overnight recovery product, the per-night cost is reasonable and the results are consistent enough to make it a repurchase.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Centella Asiatica Leaf Water (40.9%) (40.9%) | The entire hydration phase of this sleeping pack is built on centella leaf water rather than standard aqua, so every other ingredient is essentially dispersed in a concentrated centella base. That's why this overnight mask reads as genuinely calming on compromised skin instead of just sitting there as a humectant layer. | Limited for Post-Procedure |
| Triple Hyaluronic Acid (0.48% each) (1.44% total) | At 4,813 ppm each, sodium hyaluronate, hydrolyzed HA, and pure HA are dosed substantially above cosmetic-trace levels — unusual for a sleeping pack at this price. Working overnight, the three molecular weights push hydration into different stratum corneum depths while the occlusive layer above slows transepidermal water loss. | Established mechanism for Dehydration · established mechanism |
| Melatonin | Appears near the bottom of the list as a topical antioxidant. Emerging research explores melatonin's role in scavenging reactive oxygen species accumulated during daytime UV exposure, making its inclusion in a nighttime mask a thematic fit — though the dose here is modest and the benefit should be viewed as supporting rather than headline. | Not yet assessed |
| Ceramide NP | Added at a low concentration alongside hydrogenated lecithin to support barrier repair while you sleep. Ceramide NP slots into the skin's own lipid bilayer structure, helping seal the hydration delivered by the centella-and-HA base rather than acting as a standalone hero. | Established mechanism for Dryness · established mechanism |
| Polyglutamic Acid & Panthenol | Polyglutamic acid forms a flexible overnight film that extends the humectant effect of the hyaluronic acid complex, while panthenol converts to pantothenic acid in skin and reinforces barrier softness. Together they keep the mask's hydration story intact through the full sleep cycle. | Established mechanism for Dehydration · established mechanism |

Make this the final step of your evening routine in place of (or layered over) your regular moisturizer. Use 2-4 times a week for intensive hydration nights, or nightly during harsh weather.
Visibly plumped, calmed skin on the first morning. Noticeable improvement in barrier feel and reduced dehydration lines within 1-2 weeks of regular use. Full cumulative benefits around 4-6 weeks of consistent nighttime application.
The formulation's most substantive claim is the centella concentration. Research has identified madecassoside, asiaticoside, asiatic acid, and madecassic acid as the four major centella triterpenoid actives, with published work in journals including the Journal of Ethnopharmacology discussing their roles in modulating inflammatory cytokines and supporting epidermal barrier recovery. At 40.9% centella leaf water, this sleeping pack delivers those actives at concentrations well above typical cosmetic dosing — dose matters for centella, and studies using extract at higher concentrations show more pronounced calming and recovery effects than those using trace amounts. The triple hyaluronic acid system has a substantial literature base supporting multi-molecular-weight delivery as more hydrating than single-weight formulations, and at the 4,813 ppm each disclosed here, the HA component is meaningfully dosed rather than decorative. Niacinamide at typical mid-list positioning has strong peer-reviewed evidence for barrier lipid synthesis and reducing transepidermal water loss, described in British Journal of Dermatology publications among others. Ceramide NP, while included at low concentration, slots into the native stratum corneum lipid matrix and contributes to the barrier repair story, with the best evidence coming from studies on multi-ceramide formulations for compromised skin. Topical melatonin is the most speculative inclusion — research on its role as a cutaneous antioxidant and its ability to mitigate UV-generated reactive oxygen species is active but early-stage, with most studies to date being small or in-vitro. The botanical tail has traditional-use support in Korean herbal medicine but limited modern clinical validation for specific skin endpoints. Overall, the science supports the calming, hydrating, and barrier-support claims strongly, and the antioxidant nighttime-recovery framing more speculatively.
Dermatologists frequently recommend centella-based sleeping packs for patients recovering from in-office treatments, using retinoids, or dealing with chronic redness conditions like rosacea. This product fits the recommendation profile because the centella content is disclosed and genuinely substantial, the formula is fragrance-free, and the overnight format delivers calming ingredients during the skin's natural repair window. Most dermatologists writing about K-beauty products have noted that SKIN1004's decision to disclose specific active concentrations is unusually transparent for the mass market and makes their products easier to evaluate and recommend. For patients with sensitive or reactive skin, dermatologists typically suggest starting with a few nights a week to assess tolerance, especially given the botanical extract list. The sleeping pack category as a whole is generally viewed as a reasonable step in nighttime routines focused on recovery rather than active treatment.
Use as the last step of your evening routine, two to four nights per week (or nightly during harsh weather or recovery periods). After cleansing, toner, treatment serums, and any active products, scoop a dime to nickel-sized amount with a clean spatula and spread evenly across the face, including the eye area if comfortable. Allow a minute or two to absorb before getting into bed — the gel-cream texture won't transfer heavily to your pillow. In the morning, cleanse normally and continue with your routine. No rinsing required.
At roughly $19 for 100ml, this sleeping pack offers two to three months of use at a typical 3-4 nights per week frequency, putting the per-night cost well below luxury alternatives. A 30ml travel size is also available but offers worse per-milliliter value — the 100ml is the format to buy if you plan to use it regularly. What you're paying for here is the disclosed concentrations: a generic centella sleeping pack at half this price will almost certainly dose the hero ingredient at 1-2% at best, so the price premium for SKIN1004's version is buying real actives, not brand aesthetic. For anyone who responds well to centella and wants a reliable overnight recovery product, the value proposition is strong and the reorder math works out.
Anyone with sensitive, reactive, combination, or normal skin who wants an overnight hydration and calming treatment they can actually trust on active concentration. It's especially well-suited to people using retinol or acids who want a nighttime recovery layer, and to anyone who flushes easily or is recovering from a procedure and needs something gentle but genuinely effective.
If you have severely dry skin in cold climates, this sleeping pack likely won't be rich enough as a standalone and you'll need to layer. Users with a history of reactions to complex botanical extract blends should patch test carefully given the long nighttime-complex tail. And anyone who prefers a heavy, rich overnight cream experience will find this gel-cream too thin for that specific preference.

SKIN1004's Hyalu-Cica Sleeping Pack extends the brand's centella-first philosophy into the overnight format that has become a K-beauty staple. Rather than creating a generic sleeping mask, the brand took its hero ingredient and made it literally the base of the formula, adding a complex botanical 'nighttime complex' to differentiate it from the hydrating mask and moisture cream in the same line.
SKIN1004 launched in 2016 with a single-ingredient focus on Madagascar-sourced centella asiatica. The brand has built a consistent K-beauty reputation around high-centella formulations and transparent concentration disclosures rather than through peer-reviewed clinical work.
Sleeping packs need to be rinsed off in the morning.
This one is designed to absorb overnight — you wake up, cleanse normally, and go about your routine. It's a leave-on treatment, not a wash-off mask.
Melatonin in skincare makes you sleepy.
Topical melatonin is included for its antioxidant properties, not systemic sedation. The amounts used in cosmetics don't enter the bloodstream in meaningful quantities.
Two to four nights a week works well for most skin types. During harsh winter weather or after aggressive active treatments, nightly use is fine — the formula is gentle enough that there's no buildup or tolerance concern.
No. This is a leave-on sleeping pack designed to absorb overnight. In the morning, cleanse your face normally and continue with your regular routine. The lightweight gel-cream texture means you won't wake up sticky.
Yes, for most skin types this is rich enough to replace a regular nighttime moisturizer. For very dry skin in severe winter conditions, you may want to layer a richer occlusive on top, but for normal to combination skin the centella-and-HA base is sufficient.
It's included as a topical antioxidant — research is emerging around melatonin's ability to neutralize reactive oxygen species generated by UV exposure during the day. It's not an active treatment like retinol or vitamin C, but it's a thematic fit for a nighttime mask.
Yes, and it's actually a good pairing. Apply retinol first, let it absorb, then apply this mask on top. The centella and HA base helps buffer retinol irritation, and the panthenol and ceramide content support the barrier overnight while the retinol works.
Yes. The formula contains no retinoids, salicylic acid, or hydroquinone, and the centella, HA, niacinamide, and other ingredients used here are considered safe during pregnancy and breastfeeding. The topical melatonin dose is not absorbed systemically in meaningful amounts.
Most users get two to three months of use from the 100ml jar with three to four applications per week. If used nightly, expect about six to eight weeks.
