How it works
A sheet or hydrogel mask works by holding a concentrated dose of its formula against skin under occlusion, which slows evaporation and pushes more of the serum into the top layers than the same liquid would achieve on its own. Bio Collagen Real Deep Mask leads with Collagen Extract, a collagen-derived extract carried into the formula for its cushioning, moisture-holding feel on the skin's surface. It is joined by Niacinamide, a form of vitamin B3 that Korean formulators lean on for evening out tone and reinforcing the skin barrier. Further down the list, Betaine rounds out the formula as a beet-derived humectant and osmolyte that helps the skin regulate its own moisture balance. That is the case for using Bio Collagen Real Deep Mask as a regular step rather than an occasional extra.
Key benefits
- Built around Collagen Extract, Niacinamide, named on this product's own ingredient list
- An immediate hydration surge from full-face, occlusive contact time
- A cooling, de-puffing feel straight out of the fridge
- A visibly plumper, dewier finish for same-day wear
- A quick reset before makeup or an event
Inside the formula
Inside the formula
How often should I use Bio Collagen Real Deep Mask?
Two to three times a week is the standard cadence for a hydrating sheet or hydrogel mask like this one, though daily use is fine on very dry or dehydrated skin. Apply it after cleansing and toning, leave it on for the time printed on the packaging, then pat in whatever essence remains rather than rinsing it off. Skin that is actively irritated should skip a session until it calms down.
Do I rinse Bio Collagen Real Deep Mask off after use?
No, the point of this format is to pat any leftover essence into the skin rather than rinse it away, since that essence is most of what you are paying for. Remove the sheet or hydrogel once the time on the packaging is up, then continue with your regular moisturizer. Rinsing it off would wash away the hydration the mask just delivered.
Can I use Bio Collagen Real Deep Mask if I have sensitive or reactive skin?
This is formulated as a hydrating, calming step rather than an active-heavy treatment, which is generally a reasonable starting point for sensitive skin. Even so, patch test any new mask on the inner arm before a first full-face use, since sensitivity varies by individual and by what else is in a given routine. Discontinue if you notice redness or stinging that does not settle within a few minutes.
Where does Bio Collagen Real Deep Mask fit in my routine?
Use it after cleansing and toning and before serum and moisturizer, since the mask is doing the heavy hydration lifting that the rest of the routine builds on. It works well as a standalone weekly reset or folded into a longer routine on nights you have the extra few minutes. It is not a substitute for daily moisturizer or SPF.
Is Bio Collagen Real Deep Mask the authentic Korean-market formula?
Yes, this is the same formula Biodance sells through Korean retail, not a US-shelf reformulation, sourced specifically for Korean Pharmacy's US catalog. It carries its original carries its original Korean-market batch coding intact. That is the version this brand is actually known for.

Ingredient list read from biodance.com on 10 September 2026.
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 to use
- Cleanse and tone first so the mask sits against a clean surface rather than the day's residue.
- Apply it to a clean dry face and leave it undisturbed for the session rather than moving around.
- Finish with a moisturiser afterwards so the water you just added has something holding it there.
- Do not use it more than a couple of times a week, since an intensive step is not meant to be daily.
Worth knowing
- Anyone using a prescription retinoid or a strong acid exfoliant elsewhere in their routine should introduce this alongside it gradually.
- Skin that is actively broken out or irritated does best starting this once daily before moving to twice.
