How it works
The Real Fit Collagen Firming Mask Sheet is a sheet mask, used after toner, in place of your serum step, in the evening. The protein it is built around is Collagen Extract, named twenty-sixth on its own ingredient list. The same list carries Adenosine, Palmitoyl Hexapeptide-12 and Pentapeptide-3, so the protein is not the only thing on it worth naming. How much of the Collagen Extract stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. Fation sells this Collagen Extract sheet mask in Korea, and this is that version.
Key benefits
- Collagen Extract, the protein this sheet mask is built around
- Adenosine on the same list, an active
- Palmitoyl Hexapeptide-12 and Pentapeptide-3 on the same list, peptides
- Tocopherol on the same list, an antioxidant
- Tremella Fuciformis (Mushroom) Extract and Cetyl Ethylhexanoate further down the same list
- Limnanthes Alba (Meadowfoam) Seed Oil and Butyrospermum Parkii (Shea) Butter further down the same list
Key actives
18Adenosineactive
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. The panel names it eighteenth on this sheet mask's list, beside Collagen Extract.
25Tocopherolantioxidant
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. The panel names it twenty-fifth on this sheet mask's list, beside Collagen Extract.
26Collagen Extractprotein
Collagen Extract is a collagen-bearing extract, usually from fish skin or scales. In a formula it works as a humectant and a smoothing film rather than as a source of new collagen. The name on the box points at it, and it is named twenty-sixth on this sheet mask's own ingredient list.
27Palmitoyl Hexapeptide-12peptide
Palmitoyl Hexapeptide-12 is a fatted six-amino-acid peptide used for the look of firmness, usually as part of a multi-peptide blend. It is named twenty-seventh on this sheet mask's list, alongside Collagen Extract.
29Pentapeptide-3peptide
Pentapeptide-3 is a five-amino-acid peptide used for the look of expression lines. It is water soluble and is supplied as one part of a peptide blend rather than alone. It is named twenty-ninth on this sheet mask's list, alongside Collagen Extract.
Where does this sheet mask go in my routine?
After toner, in place of your serum step, in the evening. Toner goes on before it, and the rest of the routine goes on after you take the sheet mask off. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Collagen Extract and not three changes at once.
What else is on the list besides Collagen Extract?
Adenosine, Palmitoyl Hexapeptide-12 and Pentapeptide-3. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Collagen Extract sits relative to them. Further down the same panel: Tocopherol, Tremella Fuciformis (Mushroom) Extract and Cetyl Ethylhexanoate.

Ingredient list read from fation.co.kr on 30 August 2026.
27 of 29 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Limnanthes alba (meadowfoam) seed oil emollient
- Meadowfoam Seed Oil is over 95 percent long-chain fatty acids, which makes it exceptionally stable against going rancid. It is an emollient that leaves a soft, sealed feel.
- 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.
- Simethicone silicone
- A silicone that breaks surface foam. In skincare its job is usually to stop a formula foaming during manufacture rather than anything it does on skin.
15 more explained
- 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.
- Butyrospermum parkii (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.
- Sodium acrylate/sodium acryloyldimethyl taurate copolymer thickener
- This is a pre-neutralised polymer thickener that gels on contact with water and stabilises an emulsion without heat.
- Polyisobutene film former
- Polyisobutene is a synthetic polymer that forms a flexible, water-resistant film. It gives gloss and holds a formula in place, which is why it appears in lip products and long-wear textures.
- 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.
- 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.
- 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.
- 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.
- Glyceryl acrylate/acrylic acid copolymer film former
- This is a polymer that forms a moisture-holding film on the surface, usually supplied with glycerin and propylene glycol as a hydrating complex.
- Caprylyl/capryl glucoside surfactant
- Caprylyl/Capryl Glucoside is a sugar-derived cleansing surfactant. It foams modestly and is mild enough for low-pH cleansers built for reactive skin.
- Sorbitan oleate emulsifier
- Sorbitan Oleate is an emulsifier for water-in-oil formulas. It keeps a rich cream or a cleansing oil from separating.
- Tremella fuciformis (mushroom) extract plant extract
- Tremella Fuciformis is snow mushroom. Its polysaccharide holds even more water than hyaluronic acid for its weight, which is why it appears in hydrating Korean formulas as a plant alternative.
- 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.
- Collagen extract protein
- Collagen Extract is a collagen-bearing extract, usually from fish skin or scales. In a formula it works as a humectant and a smoothing film rather than as a source of new collagen.
- Palmitoyl hexapeptide-12 peptide
- Palmitoyl Hexapeptide-12 is a fatted six-amino-acid peptide used for the look of firmness, usually as part of a multi-peptide blend.

How to use
- Apply to clean skin following the timing on the pack, then remove or rinse as directed. Most masks in this format are a once- or twice-weekly treatment step rather than a daily one.
Worth knowing
- Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Collagen Extract on the list.
- Introduce this sheet mask on its own for the first week, so anything your skin does is traceable to the Collagen Extract rather than to three changes at once.
