How often should I use Dermalogy High G Exosome Mask Sheet 39g X 5ea?

A sheet mask is an occasional treatment step, a couple of times a week at most for most people, rather than a daily basic in a routine. As with any new step, give it a fair, consistent trial of a week or two before you decide whether to keep it in your routine, and stop if you notice ongoing irritation rather than pushing through it.

Do I rinse it off after?

No, pat the remaining essence into the skin rather than rinsing, and follow with your moisturizer. As with any new step, give it a fair, consistent trial of a week or two before you decide whether to keep it in your routine, and stop if you notice ongoing irritation rather than pushing through it.

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 rather than a version reformulated for US retail.

Can I use this if my skin runs sensitive?

This sheet mask is formulated with skin types like normal or 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 before it goes on your face is worth doing, 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 you judge, since a single use rarely tells you much either way. Watch for how skin feels and looks rather than for any specific number, and stop use if you notice ongoing irritation.

How it works

A sheet mask holds a serum-level essence against the skin under a fabric sheet for a set number of minutes, which is longer, closer contact than pressing a serum on with your hands. That is why it is treated as an occasional treatment step rather than a daily habit, layered in on top of an otherwise normal routine rather than replacing it. After removing it, pressing in the remaining essence rather than rinsing it off is what makes the most of a single sheet. A fair trial means giving it the same handful of uses you would give any new step before deciding whether it earns a permanent place in your routine. Consistency across days does more for a fair read than any single application, since a genuine change in how skin looks or feels builds gradually rather than all at once.

93 of 96 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.
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.
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.
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.
Isopentyldiol solvent: Isopentyldiol is a glycol used as a light solvent and humectant. It thins a formula, keeps extracts dissolved and leaves a dry finish.
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.
Polyglycerin-3 humectant: Polyglycerin-3 is a short chain of glycerin units used as a gentler, less sticky humectant. It also helps oils and water stay blended.
Diphenyl Dimethicone silicone: Diphenyl Dimethicone is a glossy silicone used to add shine and a smooth film, particularly in lip and highlighting textures.
Ammonium Acryloyldimethyltaurate/VP Copolymer thickener: This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
Triethylhexanoin emollient: Triethylhexanoin is a light ester emollient that softens skin and disperses pigment. It absorbs cleanly and is often used to thin a heavy oil phase.
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.

81 more explained

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener: This is the thickener behind most gel-cream textures. It builds a soft, bouncy gel that collapses to a light fluid as it is rubbed in.
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.
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.
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-10 Oleate emulsifier: Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
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.
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.
Ferulic Acid antioxidant: Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often.
Dextrin thickener: Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.
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.
Theobroma Cacao (Cocoa) Extract plant extract: Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
Glutathione antioxidant: Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
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.
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.
Maltodextrin film former: Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
Ascorbic Acid antioxidant: Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone.
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.
Magnesium Ascorbyl Phosphate antioxidant: Magnesium Ascorbyl Phosphate is a stable, water-soluble vitamin C salt. It works at a near-neutral pH, so it suits formulas built for skin that finds pure ascorbic acid stinging.
Ascorbyl Tetraisopalmitate antioxidant: Ascorbyl Tetraisopalmitate is an oil-soluble vitamin C ester, also sold as tetrahexyldecyl ascorbate. Being oil soluble it sits in the oil phase and is far more stable than pure vitamin C.
Sodium Ascorbyl Phosphate antioxidant: Sodium Ascorbyl Phosphate is a water-soluble, stable vitamin C salt. It works at near-neutral pH, so it appears in formulas aimed at skin that pure ascorbic acid leaves stinging.
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.
Resveratrol antioxidant: Resveratrol is an antioxidant from grape skin and Japanese knotweed. It is used for the look of dullness and is often paired with ferulic acid, which keeps it stable.
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.
Sodium Starch Octenylsuccinate absorbent: Modified starch used as a very soft powder. It absorbs oil, blurs the look of texture, and takes the shine off a formula.
Sodium PCA humectant: Sodium PCA is one of the substances skin makes for itself to hold water, part of what dermatology calls the natural moisturising factor. Added to a formula it is a strong humectant that suits skin that dehydrates quickly.
Calcium Pantothenate vitamin: Calcium Pantothenate is the calcium salt of pantothenic acid, vitamin B5. It is the salt form of the same vitamin panthenol converts to, and it hydrates and conditions.
Sodium Lactate humectant: Sodium Lactate is the salt of lactic acid and one of the components of skin's own natural moisturising factor. At the levels used here it is a humectant and buffer rather than an exfoliant.
Caprylic/Capric Triglyceride emollient: Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
Palmitic Acid fatty acid: Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
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.
Aspartic Acid amino acid: Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
Polyglyceryl-10 Diisostearate emulsifier: A polyglycerin ester carrying two fatty chains, which makes it more oil-loving than the single-chain version. It suits cleansing oils and rich creams.
Pca humectant: PCA is pyrrolidone carboxylic acid, one of the components of the natural moisturising factor skin makes for itself. It holds water at the surface, and its salts do the same job.
Glucose humectant: Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
Gardenia Florida Fruit Extract plant extract: Gardenia Fruit Extract is the traditional East Asian yellow dye plant. In skincare it is used as an antioxidant extract, and it can tint a formula.
Sodium Polyphosphate chelator: Sodium Polyphosphate is a chain phosphate salt that ties up metal ions. That keeps a formula stable and stops hard water flattening a cleanser foam.
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.
Tocopheryl Acetate antioxidant: Tocopheryl Acetate is a stable vitamin E ester that skin converts to tocopherol. It is used as an antioxidant and a light emollient and holds up better than plain vitamin E in a formula.
Pyridoxine Hcl vitamin: Pyridoxine HCl is the water-soluble salt of vitamin B6. It is a conditioning vitamin, most often part of a B-complex blend.
Glycine amino acid: Glycine is the smallest amino acid and one of the free amino acids skin holds to keep water in the outer layer. In a formula it is a humectant and a mild buffer.
Alanine amino acid: Alanine is a free amino acid skin uses as part of its own moisture-holding system. In a formula it hydrates and conditions.
Sodium Ascorbate vitamin: The sodium salt of vitamin C. It is less acidic than pure ascorbic acid and dissolves readily in water, though like ascorbic acid it still oxidises once in solution.
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.
Biotin vitamin: Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
Pyridoxine vitamin: Pyridoxine is vitamin B6. In a formula it is a conditioning vitamin, most often in B-complex blends and scalp products.
Folic Acid vitamin: Folic Acid is vitamin B9. It is used in a formula as a conditioning vitamin, usually as part of a B-complex blend.
Lecithin emulsifier: Lecithin is a soy or sunflower-derived phospholipid, the same class of molecule cell membranes are built from. It emulsifies oil into water and is the basis of the liposomes formulators use to carry actives.
Polysorbate 20 emulsifier: Polysorbate 20 is a solubiliser: it dissolves small amounts of oil or fragrance into a watery formula so nothing separates or floats.
Menadione vitamin: Menadione is a synthetic form of vitamin K. In a formula it is used at very low levels as a conditioning vitamin.
Serine amino acid: Serine is one of the most abundant free amino acids in the outer layer of skin, where it helps hold water. Added to a formula it is a humectant.
Valine amino acid: Valine is an essential amino acid used as a humectant alongside the rest of an amino acid block.
Dipeptide Diaminobutyroyl Benzylamide Diacetate peptide: This is a two-amino-acid peptide, sold as Syn-Ake, used for the look of expression lines. Its structure was modelled on a component of snake venom, though nothing of the venom itself is in it.
Isoleucine amino acid: Isoleucine is an essential amino acid used as a conditioning humectant within an amino acid complex.
Threonine amino acid: Threonine is an essential amino acid used in skincare as a humectant, normally as part of an amino acid complex rather than alone.
Proline amino acid: Proline is an amino acid abundant in collagen and one of skin's own humectants. Added to a formula it holds water in the outer layer.
Hydroxypropyltrimonium Hyaluronate humectant: Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
Silica absorbent: Silica is finely milled mineral, essentially very pure sand. It absorbs oil, stops powders clumping and soft-focuses the look of pores and fine lines.
Phenylalanine amino acid: Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
Histidine amino acid: Histidine is an amino acid used as a humectant and a buffer, part of skin's own free amino acid pool.
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.
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.
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.
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.
Sodium Acetylated Hyaluronate humectant: Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
Copper Tripeptide-1 peptide: Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
Riboflavin vitamin: Riboflavin is vitamin B2, and it is a strong yellow, so a formula carrying it often has a colour nobody added on purpose.
Thiamine Hcl vitamin: Thiamine is vitamin B1, supplied as its hydrochloride salt so it dissolves in water. It is a conditioning vitamin and usually appears as part of a B-complex.
Linoleic Acid fatty acid: Linoleic Acid is an essential omega-6 fatty acid and the main fatty acid in sunflower, safflower and rosehip oil. In a formula it is a lipid that softens and sits in the outer layer.
Beta-Carotene antioxidant: Beta-Carotene is an orange plant pigment and a vitamin A precursor. It is used as an antioxidant and it tints a formula, which is often why it is there.
Hyaluronic Acid humectant: Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
Sodium Hyaluronate Crosspolymer humectant: Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
Potassium Hyaluronate humectant: Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.
Tripeptide-1 peptide: Tripeptide-1 is the copper-free version of the classic three-amino-acid peptide. It is used for the look of firmness in formulas that avoid copper's blue tint.
Palmitoyl Tripeptide-1 peptide: Palmitoyl Tripeptide-1 is a short peptide with a fatty tail added so it can travel through the oily outer layer of skin. It is used for the look of firmness and is almost always paired with palmitoyl tetrapeptide-7.
Tripeptide-2 peptide: Tripeptide-2 is a peptide of three amino acids. The number after the name identifies one specific sequence rather than a strength, and it is used in blends for the look of firmness.
Hexapeptide-11 peptide: Hexapeptide-11 is a yeast-derived six-amino-acid peptide used for the look of resilience and firmness.
Acetyl Hexapeptide-8 peptide: Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
Palmitoyl Tetrapeptide-7 peptide: Palmitoyl Tetrapeptide-7 is a four-amino-acid peptide with a fatty tail, used for the look of fine lines. With palmitoyl tripeptide-1 it forms the pairing sold as Matrixyl 3000.
Palmitoyl Pentapeptide-4 peptide: Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
Hexapeptide-9 peptide: Hexapeptide-9 is a six-amino-acid peptide used for the look of firmness and elasticity. It is water soluble and appears in peptide blends rather than alone.
Nonapeptide-1 peptide: Nonapeptide-1 is a nine-amino-acid peptide used for the look of uneven tone rather than for firmness, which makes it unusual among cosmetic peptides.

Worth knowing

Patch test a new mask on the jaw first if your skin reacts easily to something new.
Do not leave a sheet mask on well past its stated time; a dried-out sheet can pull moisture from skin rather than give it.
