How to use
- Use the 5 PDRN Collagen Vitalizing Hydrogel Eye Patch 85g/60ea in the evening, after toner, on clean skin under each eye.
- Apply the patches to clean, dry under-eye skin. Leave on for 10 minutes or longer if desired, then remove and gently massage the remaining serum into the skin. For external use only; avoid direct contact with the eyes.
- Toner first so the skin is clean and slightly damp. Take the patches off at the time the pack gives, pat in what is left, then carry on to your cream.
- Two or three evenings a week. Do not reuse a patch or leave one on overnight; once the essence has gone the sheet works against the skin it is sitting on.
Does this product contain added fragrance?
No. Neither fragrance nor parfum appears on the ingredient list for COSRX 5 PDRN Collagen Vitalizing Hydrogel Eye Patch 85g/60ea. Those are the two names a cosmetic label uses for an added scent blend, so a formula carrying one would name it. The full list is printed in the Ingredients section of this page.
Are any declarable fragrance allergens listed?
No. None of the 26 fragrance components that EU cosmetic labelling requires to be named individually appear on the ingredient list for COSRX 5 PDRN Collagen Vitalizing Hydrogel Eye Patch 85g/60ea. They are the components most often reported as contact allergens, which is why that rule names them one by one.
Does this product contain denatured or SD alcohol?
No. The ingredient list for COSRX 5 PDRN Collagen Vitalizing Hydrogel Eye Patch 85g/60ea names no denatured alcohol, SD alcohol or ethanol. Fatty alcohols such as cetyl and cetearyl alcohol are a different class of ingredient, used as emollients and thickeners, and are not counted here.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

45 of 47 explained
- AQUA/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.
- 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.
- 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.
- METHYLPROPANEDIOL humectant
- Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
- CHONDRUS CRISPUS POWDER 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.
- CELLULOSE GUM thickener
- Cellulose Gum is plant cellulose modified to dissolve in water. It thickens, holds particles in suspension and gives a smooth, slippery body.
- 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.
- 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.
- 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.
- 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.
33 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.
- 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.
- 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.
- SODIUM POLYACRYLATE thickener
- Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
- 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.
- 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.
- POLYGLYCERYL-10 MYRISTATE emulsifier
- Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.
- 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.
- 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.
- 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.
- 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.
- CAFFEINE active
- Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the skin.
- 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.
- 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.
- COLLAGEN protein
- Collagen is the structural protein that makes up most of the dermis. Applied on top it is far too large to enter skin, so in a formula it works as a humectant and a smoothing film former.
- 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.
- PANTOLACTONE humectant
- Pantolactone is a panthenol relative used as a conditioning humectant. It softens the outer layer of skin and helps a formula feel comfortable.
- 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.
- 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.
- 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.
- 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.
- 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.
- ORYZA SATIVA (RICE) EXTRACT plant extract
- Rice Extract is the anchor of the Korean rice-skincare category. It carries starches, amino acids and ferulic acid, and it is used for the look of dullness and for a soft, blurred finish.
- 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.
- CAULERPA LENTILLIFERA EXTRACT plant extract
- Extract of sea grape, a green seaweed. It carries mineral-rich polysaccharides and is used as a hydrating marine 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.
- 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.
- 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.
- 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.
- 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.
- HYDROLYZED RICE PROTEIN protein
- Hydrolyzed Rice Protein is rice protein broken into small fragments. It is a humectant and film former that leaves a soft, smooth finish.
- 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.
- 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.
