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?

Niacinamide, Allantoin and Adenosine. 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: Dipotassium Glycyrrhizate, Galactomyces Ferment Filtrate and Lactobacillus Ferment.

Key actives

4Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named fourth on this sheet mask's list, alongside Collagen Extract.

All products with Niacinamide

16Allantoinactive

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. It is named sixteenth on this sheet mask's list, alongside Collagen Extract.

All products with Allantoin

20Adenosineactive

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. It is named twentieth on this sheet mask's list, alongside Collagen Extract.

All products with Adenosine

24Collagen 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. It is the entry this sheet mask is named after, and the list carries it.

All products with Collagen Extract

29Dipotassium Glycyrrhizateactive

Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. The panel names it twenty-ninth on this sheet mask's list, beside Collagen Extract.

Biodance Bio-Collagen Real Deep Mask (16ea)

34 of 34 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.
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.
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.
Ceratonia Siliqua (Carob) Gum thickener: Carob Gum is a seed polysaccharide from the carob tree. It thickens a formula and gives a soft, cushioned body.
Chondrus Crispus Extract 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.
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.
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.
Algin thickener: Algin is a brown-seaweed polysaccharide. It thickens, forms a film, and sets into a rubbery gel when calcium is added, which is how a peel-off modelling mask works.
Agar thickener: Agar is a seaweed polysaccharide that sets into a firm gel. It is the gelling agent behind jelly masks and thick sleeping packs.
Hydroxyacetophenone preservative booster: Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
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.

22 more explained

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.
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.
Sucrose humectant: Sucrose is table sugar, used here as a humectant. It draws water into the outer layer of skin and, in a scrub, doubles as the physical grain.
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.
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.
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.
Galactomyces Ferment Filtrate ferment: Galactomyces Ferment Filtrate is a yeast ferment filtered clear, the ingredient that made the Korean and Japanese essence category. It carries amino acids, vitamins and organic acids and is used for the look of dullness and rough texture.
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.
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.
Pyrus Communis (Pear) Fruit Extract plant extract: Pear Fruit Extract carries fruit sugars and mild fruit acids. It is used as a hydrating extract with a very light smoothing effect on the surface.
Rosa Damascena Flower Water plant extract: Rosa Damascena Flower Water is the water left from distilling rose petals. It is used in place of plain water as a base and carries the scent and trace compounds of the distillation.
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.
Iris Florentina Root Extract plant extract: Iris Florentina Root Extract, or orris root, is a long-standing perfumery and skincare ingredient. It is used as a conditioning extract with a soft, powdery scent.
Cucumis Melo (Melon) Fruit Extract plant extract: Melon Fruit Extract carries fruit sugars and a natural antioxidant enzyme system. It is used as a light hydrating extract.
Hedera Helix (Ivy) Leaf/Stem Extract plant extract: Ivy Leaf and Stem Extract carries saponins, plant compounds that foam slightly in water. It is used in body and eye formulas for the look of puffiness.
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.
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.
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.
Lactobacillus Ferment ferment: Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin.
Bifida Ferment Filtrate ferment: Bifida Ferment Filtrate is the liquid strained off a bifidobacteria culture, with the cells filtered out. It is the fraction the first-essence category is built on and is used for the look of tired, reactive skin.
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.
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.

How it works

The Bio-Collagen Real Deep Mask is a 16ea 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-fourth on its own ingredient list. The same list carries Niacinamide, Allantoin and Adenosine, 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. Biodance sells this Collagen Extract sheet mask in Korea, and this is that version.

How to use

Use the Bio-Collagen Real Deep Mask after toner, in place of your serum step, in the evening.
Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
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

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.

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

Topical collagen is a very large molecule that's too big to absorb into the skin.
Michelle Henry, MDDermatologist, Cosmopolitan
Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
