Where does this sleeping mask go in my routine?

As the final step of the evening routine, over your usual moisturizer or in place of it. Toner goes on before it, and the rest of the routine goes on after you take the sleeping 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 Sodium DNA and not three changes at once.

Is this the Korean-market sleeping mask or a US version?

The Korean-market one, Sodium DNA and all. We match this sleeping mask to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.

What else is on the list besides Sodium DNA?

Adenosine, Gluconolactone and Acetyl Hexapeptide-8. The order they are printed in on this sleeping mask's panel is the order on the box, so you can see where Sodium DNA sits relative to them. Further down the same panel: Copper Tripeptide-1, Palmitoyl Tetrapeptide-7 and Nonapeptide-1.

How it works

The GIM PDRN Deep Sleep Mask is a 80ml sleeping mask, used as the final step of the evening routine, over your usual moisturizer or in place of it. The active it is built around is Sodium DNA, named eighteenth on its own ingredient list. The same list carries Adenosine, Gluconolactone and Acetyl Hexapeptide-8, so the active is not the only thing on it worth naming. How much of the Sodium DNA stays on the skin, and for how long, is decided by the sleeping mask format rather than by the list alone. This is the Original Korean Formula, the sleeping mask Isntree sells in Korea, Sodium DNA and all.

on the list

1 of 3

43 of 44 explained

Water(Aqua) 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.
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.
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.
Methyl Trimethicone silicone: Methyl Trimethicone is a light, volatile silicone chosen for a notably dry finish. It thins a formula and disperses powders evenly.
Dimethiconol silicone: Dimethiconol is a high-molecular-weight silicone that leaves a longer-lasting smooth film than dimethicone. It is used for lasting slip and shine.
Vinyl Dimethicone silicone: Vinyl Dimethicone is a silicone used as a building block of the crosspolymer gels that give a formula its soft, blurring feel.
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.
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.
Polypropylsilsesquioxane silicone: A silicone resin that dries into a hard, water-resistant film. It is what makes a formula stay put through sweat instead of sliding.
Dimethicone/Vinyl Dimethicone Crosspolymer silicone: This is a silicone elastomer, a soft springy gel. It fills the look of fine texture and gives the velvety, blurred finish of a primer.
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.
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.

31 more explained

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.
Coptis Japonica Root Extract plant extract: Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin.
Porphyra Yezoensis Extract plant extract: Nori laver, the gim eaten in Korea and Japan. Its extract carries porphyran, a water-holding sugar, along with minerals and amino acids.
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.
Sodium DNA active: Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to.
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.
Hydrolyzed Gardenia Florida Extract plant extract: Hydrolyzed Gardenia Florida Extract is gardenia extract broken into smaller fragments so a water-based formula can carry it evenly.
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.
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.
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.
Undaria Pinnatifida Extract plant extract: Extract of the brown seaweed Korean cooking calls miyeok. It carries fucoidan and alginates, both strong water-holding polysaccharides.
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.
Hydrolyzed Sodium Hyaluronate 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 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.
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.
Gluconolactone exfoliant: Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
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.
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.
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.
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.
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.
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.
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 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.
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.
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.
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.
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.

How to use

Finish your usual evening routine first, then apply this over the top as the last step.
Spread a thin even layer rather than a thick one, since a heavy coat transfers onto the pillow.
Leave it on overnight and rinse in the morning before your daytime routine.
Do not use it on the same night as a strong exfoliant while you are still introducing either product.

Worth knowing

Patch test this sleeping mask on a small area and wait a day before using it more widely, especially with Sodium DNA on the list.
Gluconolactone on this list makes this sleeping mask an exfoliating step, so do not stack it with another one on the same night.
