How it works
The MD STEM III Clinical Recovery Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named fifth on its own ingredient list. The same list carries Allantoin, Asiaticoside and Madecassic Acid, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum IOPE sells in Korea, Niacinamide and all.

Inside the formula
Inside the formula
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. 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 Niacinamide and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Niacinamide and all. We match this serum 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 Niacinamide?
Allantoin, Asiaticoside and Madecassic Acid. The order they are printed in on this serum's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Asiatic Acid, Adenosine and Hydrolyzed DNA.
Not on the ingredient list below: fragrance or parfum, essential oils, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

31 of 32 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.
- 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.
- 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.
- 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.
- 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.
- Dimethicone silicone
- Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.
- 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.
- Polyglyceryl-6 Caprylate emulsifier
- A polyglycerin emulsifier with a short fatty chain, which makes it more water-loving than its longer-chain relatives. It suits cleansing waters and micellar formulas.
- Polyglyceryl-4 Caprate emulsifier
- Polyglyceryl-4 Caprate is a mild sugar-derived solubiliser used to dissolve fragrance and oil into watery formulas.
19 more explained
- 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.
- 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.
- Alcohol solvent
- Alcohol here means ethanol. It dissolves ingredients water cannot, evaporates fast so a formula sets quickly and does not feel heavy, and thins texture. In quantity it can leave dry or reactive skin feeling tight, which is why many Korean formulas avoid it and some deliberately use it for a fast, weightless finish.
- Asiaticoside active
- Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
- Sodium Methyl Stearoyl Taurate surfactant
- A taurine-based surfactant. Taurates foam well while staying mild, and they keep working in hard water where a soap does not.
- Madecassic Acid active
- Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
- Mannitol humectant
- Mannitol is a sugar alcohol used as a humectant and antioxidant. It hydrates and helps stabilise the rest of the formula against oxidation.
- Asiatic Acid active
- Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
- 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.
- Hydrolyzed Dna active
- Hydrolyzed DNA is DNA cut into short fragments so it dissolves and spreads. It is the same ingredient family as sodium DNA and polydeoxyribonucleotide, the one Korean formulas market as PDRN.
- 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.
- 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.
- Theobroma Cacao 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.
- Allium Cepa (Onion) Bulb Extract plant extract
- Onion Bulb Extract carries quercetin and sulphur compounds. Korean formulas use it for the look of blemish marks and uneven tone, and it is the namesake ingredient of the onion skincare line.
- Acetyl Tetrapeptide-11 peptide
- Acetyl Tetrapeptide-11 is a four-amino-acid peptide used for the look of firmness, and it is the usual partner to acetyl tetrapeptide-9.
- 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
- After toner, before moisturizer.
- Apply a few drops over the face and neck.
- Follow with a moisturizer.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Niacinamide rather than to three changes at once.
