How it works
Round Lab Camellia Deep Collagen Firming Gel Mask is built as a sheet mask, so its texture and finish are designed around one specific place in a routine rather than several. The formula's own ingredient list carries Niacinamide, Adenosine, Panthenol (Pro-Vitamin B5) among its named ingredients, placed at a level consistent with a sheet mask rather than a spot treatment. The texture is built for use as an occasional treatment step, after cleansing and toner, before your regular serum or moisturizer, which is why it behaves differently on skin than a product meant for a different point in a routine. This is the Korean-market formula of the camellia deep collagen firming gel mask, the version sold on shelves in Korea rather than a formula reworked for a different market.
Key benefits
- Camellia Deep Collagen Firming Gel Mask is Round Lab's wash-off mask, sourced for the Korean market rather than reformulated for US shelves.
- Carries Hydrolyzed Collagen, which is hydrolyzed collagen, added for its film-forming, skin-conditioning feel.
- Carries Niacinamide, which is the brightening, barrier-supporting workhorse behind most Korean tone-evening formulas, and it layers easily under sunscreen and makeup.
- Carries Panthenol, which is provitamin B5, a humectant that helps a formula feel less tight after it dries down.
- Ships with the Korean-market barcode and batch code intact, the same box sold on Korean shelves rather than a US repack.
- Suited to shoppers targeting uneven tone and dark spots.
Inside the formula
Inside the formula
Is this the same formula sold in Korea, or a version made for the US market?
This is the Korean-market formula, the same one sold on shelves in Korea, not a separate version reformulated for US retail. The pack you open matches what a shopper in Seoul buys.
Where does this step go in a routine?
It belongs as an occasional treatment step, after cleansing and toner, before your regular serum or moisturizer. Placing it earlier or later than that changes how it feels going on and how well the steps after it absorb, so keeping it in that order is worth doing even on a simplified routine.
Can I use this if my skin runs sensitive?
This sheet mask is formulated with skin types like normal skin, dry skin in mind, but any new product is worth a patch test first if your skin reacts easily. A short patch test on the inside of your arm or behind an ear is worth doing with any new product before it goes on your face, and that goes for sensitive skin most of all.
How long before I will know if this is right for my skin?
Give it a full week or two of consistent use before judging, since a single use rarely tells you much either way. Watch for how skin feels rather than for any specific number, and stop use if you notice ongoing irritation.

43 of 43 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.
- 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.
- 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.
- 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.
- Hydrolyzed Collagen protein
- Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
- Soluble Collagen protein
- Soluble Collagen is collagen kept in its intact triple-helix form and dissolved rather than cut up. It sits on the surface as a water-holding film.
- 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.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- 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.
- 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.
- Chondrus Crispus Powder plant extract
- Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
31 more explained
- 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.
- Camellia Japonica Flower Extract plant extract
- Camellia Japonica Flower Extract comes from the flower of the Korean camellia. It is used as a conditioning, hydrating extract.
- Shea Butter emollient
- Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
- Hydroxyethyl Urea humectant
- Hydroxyethyl Urea is a humectant that holds a lot of water for its size and stays comfortable at high levels. It is used where a formula needs to feel deeply hydrating without oil.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- Acrylates Copolymer film former
- Acrylates Copolymer is a synthetic polymer that forms a film as the water leaves. It holds a formula in place, controls shine and helps a texture stay put.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
- Quercetin antioxidant
- Quercetin is one of the most widespread plant flavonoids, found in onion skin, apple peel and tea. It is a plant antioxidant and is yellow, so it tints a formula.
- Ethylhexyl Olivate emollient
- An ester built from olive oil fatty acids. It gives the softening feel of a plant oil with a lighter, less greasy finish.
- Xanthan Gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
- Hydrogenated Polyisobutene emollient
- Hydrogenated Polyisobutene is a stabilised synthetic hydrocarbon used in place of mineral oil. It is an emollient that leaves a smooth, cushioned film.
- Polyglyceryl-4 Caprate emulsifier
- Polyglyceryl-4 Caprate is a mild sugar-derived solubiliser used to dissolve fragrance and oil into watery formulas.
- Polyglyceryl-6 Caprylate emulsifier
- A polyglycerin emulsifier with a short fatty chain, which makes it more water-loving than its longer-chain relatives. It suits cleansing waters and micellar formulas.
- Sodium Acrylates Copolymer thickener
- An acrylate polymer that thickens water and can hold many times its own weight in it. It gives a gel body without any oil.
- 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.
- Cellulose Gum thickener
- Cellulose Gum is plant cellulose modified to dissolve in water. It thickens, holds particles in suspension and gives a smooth, slippery body.
- 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.
- Polyglyceryl-4 Oleate emulsifier
- Polyglyceryl-4 Oleate is a plant-derived emulsifier used in cleansing oils so they rinse cleanly.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- Ethylhexyl Palmitate emollient
- Ethylhexyl Palmitate is a palm-derived ester used as a light emollient and a solvent for pigment. It gives a smooth, non-greasy slip.
- Inositol humectant
- Inositol is a sugar-like compound found in the body. In skincare it is a humectant that also helps a formula feel conditioning rather than merely wet.
- Sodium Hyaluronate humectant
- Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
- Sorbitan Isostearate emulsifier
- Sorbitan Isostearate is a mild emulsifier that holds water into oil, the direction a cleansing balm or an oil-based cream needs.
- Cyanocobalamin vitamin
- Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin.
- Dimethyl Isosorbide solvent
- Dimethyl Isosorbide is a solvent used to dissolve actives that water and oil both reject, and to carry them evenly through the outer layer of skin. It appears in vitamin C and retinoid formulas for exactly that reason.
- Hydroxypinacolone Retinoate active
- Hydroxypinacolone Retinoate is a retinoid ester that binds skin's retinoid receptors directly, with no conversion step. Brands use it where they want retinoid-style results with less of the flaking retinol brings.
- 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.
- 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.
- Potassium Chloride mineral
- Potassium Chloride is a mineral salt used to bring a formula closer to the salt balance of skin, most often as part of a sea-water or mineral-water blend.
- Glucomannan thickener
- Glucomannan is a konjac root polysaccharide. It thickens, holds a great deal of water and leaves a smooth, cushioned film.

How to use
- Use the Camellia Deep Collagen Firming Gel Mask after toner, in place of your serum step, in the evening.
- Apply the mask to your face and leave it on until it becomes transparent.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Remove the sheet before it dries out completely, since a fully dried sheet can pull moisture back out of skin rather than leaving it behind.
- Press the leftover essence into skin rather than rinsing it away, so the formula is not wasted after the sheet comes off.
