How it works
Medicube PDRN Pink One Day Serum is an ampoule built for the treatment step right after toner. Its ingredient list leads with Niacinamide, Panthenol, and Adenosine, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Niacinamide does the most work here as a tone and texture, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the treatment step right after toner, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the PDRN Pink One Day Serum line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.
Key benefits
- Built around Niacinamide, positioned for tone and texture.
- Built around Panthenol, positioned for comfort.
- Built around Adenosine, positioned for firming look.
- Formulated as an ampoule for the treatment step right after toner.
- The Korean-market Medicube formula for PDRN Pink One Day Serum, matching what Medicube sells in Korea rather than a US-reformulated line.
Inside the formula
Inside the formula
Medicube PDRN Pink One Day Serum
What does the PDRN Pink One Day Serum actually contain?
Its ingredient list is led by Niacinamide, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the PDRN Pink One Day Serum?
Use this ampoule as the treatment step right after toner. To apply, press a small amount into cleansed, toned skin and follow with moisturizer. Keep it to AM/PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the PDRN Pink One Day Serum the same formula sold in Korea, or a US version?
This PDRN Pink One Day Serum is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the PDRN Pink One Day Serum with other actives in my routine?
Yes, as long as it is used in its own step, the treatment step right after toner, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the PDRN Pink One Day Serum suited for?
It suits most skin types looking for treatment step right after toner rather than a single acute problem. It comes in a 10ea format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

Ingredient list read from incidecoder.com on 30 August 2026.
41 of 42 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.
- 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.
- Polyglyceryl-3 humectant
- Polyglyceryl-3 is three glycerin units joined together. On its own it is a humectant, and it is the backbone the polyglyceryl-3 emulsifiers are built on.
- 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.
- 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.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- 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.
- 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.
- PEG-8 humectant
- PEG-8 is a short polyethylene glycol chain. It holds water, keeps a formula fluid, and dissolves ingredients water alone cannot.
- Methyl Gluceth-20 humectant
- Methyl Gluceth-20 is a sugar-derived humectant. It holds water in the outer layer of skin and gives a smooth, cushioned slip that plain glycerin does not.
- Methyl Gluceth-10 humectant
- A sugar-derived humectant, the lighter counterpart of methyl gluceth-20. It holds water and gives a smooth, non-tacky slip.
29 more explained
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
- Tromethamine pH adjuster
- Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
- 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.
- 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.
- C12-14 Alketh-12 emulsifier
- C12-14 Alketh-12 is a solubiliser used to keep oils and fragrance dissolved in a water-based formula.
- 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.
- 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.
- 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.
- Saccharide Hydrolysate humectant
- Saccharide Hydrolysate is a mixture of plant sugars broken down for use as a humectant. It holds water in the outer layer.
- 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.
- Salmon Egg Extract active
- Salmon Egg Extract is the source material behind many PDRN products, carrying DNA fragments, proteins and lipids. It is used as a conditioning active in the same formulas.
- 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.
- 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.
- Soluble Elastin protein
- Soluble Elastin is elastin processed so it dissolves in water instead of staying fibrous. It sits on the surface as a conditioning film.
- 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.
- Microcrystalline Cellulose absorbent
- Microcrystalline Cellulose is purified cellulose ground fine. It thickens, holds powders in suspension and gives a soft, matte feel.
- 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.
- 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.
- 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.
- Soluble Collagen protein
- Soluble Collagen is collagen kept in its intact triple-helix form and dissolved rather than cut up. It sits on the surface as a water-holding film.
- 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.
- 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.
- 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.
- Sorbitan Laurate emulsifier
- Sorbitan Laurate is a light emulsifier and solubiliser, used to keep small amounts of oil or fragrance dissolved in a watery formula.
- 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.
- 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.
- Cetyl Hydroxyethylcellulose thickener
- Cellulose modified with a fatty cetyl chain. It thickens water and holds small amounts of oil in place at the same time.
- Acetyl Dipeptide-1 Cetyl Ester peptide
- Acetyl Dipeptide-1 Cetyl Ester is a two-amino-acid peptide with a fatty cetyl tail attached, which lets it sit in the oil phase of a formula rather than only the water phase.

How to use
- Use one vial in the evening after toner, in the place your serum would otherwise take.
- Snap the vial, use all of it across the face and neck, then throw the vial away.
- Press it in, then moisturizer over the top once it has stopped feeling wet.
- One vial per session rather than half a vial twice. Do not keep an opened vial for the next night.
Worth knowing
- Patch test on the inner arm before the first full-face application, especially on skin that reacts easily to new products.
- Stop use and rinse off if stinging, burning, or new redness shows up rather than pushing through discomfort.
