How it works
Medicube Deep Peptide Radiance Sheet Mask is a sheet mask built for a weekly care step layered after toner. Its ingredient list leads with Niacinamide, Panthenol, and Allantoin, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Niacinamide does the most work here as a tone and texture, and the remaining actives round out the texture and finish rather than compete for attention. Placed as a weekly care step layered after toner, it is meant to be used PM rather than swapped freely between steps. Because this is the Korean-market version of the Deep Peptide Radiance Sheet Mask line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

Medicube Deep Peptide Radiance Sheet Mask
What does the Deep Peptide Radiance Sheet Mask actually contain?
Its ingredient list is led by Niacinamide, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the Deep Peptide Radiance Sheet Mask?
Use this sheet mask as a weekly care step layered after toner. To apply, unfold the sheet over a cleansed and toned face, leave on for fifteen to twenty minutes, then peel off and pat in the leftover essence. Keep it to PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the Deep Peptide Radiance Sheet Mask the same formula sold in Korea, or a US version?
This Deep Peptide Radiance Sheet Mask is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the Deep Peptide Radiance Sheet Mask with other actives in my routine?
Yes, as long as it is used in its own step, a weekly care step layered after toner, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the Deep Peptide Radiance Sheet Mask suited for?
It suits most skin types looking for weekly care step layered after toner rather than a single acute problem. It comes in a 20g format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

Ingredient list read from incidecoder.com on 30 August 2026.
37 of 37 explained
- Water solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
- Glycerin humectant
- Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Niacinamide active
- Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- Cetyl Ethylhexanoate emollient
- Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
- Panthenol humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- Allantoin active
- Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
- Xylitol humectant
- Xylitol is a sugar alcohol humectant. It holds water in the outer layer of skin and is often paired with anhydroxylitol and xylitylglucoside as a hydration trio.
- Centella Asiatica Leaf Extract plant extract
- Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
- Lactobacillus Ferment Lysate ferment
- Lactobacillus Ferment Lysate is the ferment with the bacterial cells broken open, so their contents are in the formula too. It is a conditioning ferment used in barrier-focused products.
25 more explained
- Lactococcus Ferment Lysate ferment
- Lactococcus Ferment Lysate is a lactic-culture ferment with the bacterial cells broken open, so their contents are in the formula too. It is used as a conditioning ferment in barrier-focused products.
- Bifida Ferment Lysate ferment
- Bifida Ferment Lysate is a bifidobacteria ferment with the cells broken open. It is the ingredient behind the first-essence category and is used for the look of tired, reactive skin.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- Sorbitan Laurate emulsifier
- Sorbitan Laurate is a light emulsifier and solubiliser, used to keep small amounts of oil or fragrance dissolved in a watery formula.
- Hydrogenated Lecithin emulsifier
- Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
- Hydrolyzed Hyaluronic Acid humectant
- Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- Asiaticoside active
- Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
- Madecassic Acid active
- Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
- Asiatic Acid active
- Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
- Acetyl Dipeptide-1 Cetyl Ester peptide
- Acetyl Dipeptide-1 Cetyl Ester is a two-amino-acid peptide with a fatty cetyl tail attached, which lets it sit in the oil phase of a formula rather than only the water phase.
- Acetyl Hexapeptide-1 peptide
- Acetyl Hexapeptide-1 is a six-amino-acid peptide used for the look of even tone. It is one of the few peptides aimed at pigment rather than at lines.
- Palmitoyl Tripeptide-5 peptide
- Palmitoyl Tripeptide-5 is a fatted three-amino-acid peptide used for the look of firmness and fine lines. The palmitoyl tail is what lets it cross an oily surface.
- Beta-Glucan polysaccharide
- Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
- Ceramide NP barrier lipid
- Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
- Acetyl Octapeptide-3 peptide
- Acetyl Octapeptide-3 is an eight-amino-acid peptide used for the look of expression lines. It is usually paired with acetyl hexapeptide-8 rather than used alone.
- Hydrogenated Vegetable Oil occlusive
- Plant oil hardened by hydrogenation. It behaves as a soft solid, so it gives balms and sticks their body and slows water loss from the surface.
- Behenyl Alcohol fatty alcohol
- Behenyl Alcohol is a long-chain fatty alcohol used to thicken and stabilise a cream. It gives a richer, more velvety body than cetyl alcohol.
- Polyglyceryl-3 Methylglucose Distearate emulsifier
- Polyglyceryl-3 Methylglucose Distearate is a sugar-derived emulsifier known for a light, non-soapy feel. It builds gel-creams that do not read as rich.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
- Adenosine active
- Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Ethylhexylglycerin preservative booster
- Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
- Disodium EDTA chelator
- EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.

How to use
- Use it in the evening after toner, before moisturizer, on skin still damp from the toner.
- Set the sheet at the eyes and mouth first, then smooth outwards so nothing is left bridging.
- Remove it at the printed time and press what is left into the skin rather than washing it off.
- Two or three evenings a week. Do not follow it with an exfoliating step on the same night.
Worth knowing
- Patch test on the inner arm before the first full-face application, especially on skin that reacts easily to new products.
- Stop use and rinse off if stinging, burning, or new redness shows up rather than pushing through discomfort.
