How it works
As a serum, Cemenrete Calcium Volume Ampoule Plus is built to do one job well within a layered Korean routine rather than substitute for the steps around it. Dr Melaxin positions the line around a specific texture and finish that suits the format, whether that is a quick-absorbing fluid or a cushioned, richer feel. It is designed to be used at a consistent point in the routine so its effect builds with repeated use rather than a single application. Dr Melaxin sources this SKU as the authentic Korean-market formula, the same version sold on shelf in Korea, rather than a separate US-facing reformulation.
Key benefits
- Formulated as a serum for its specific place in a layered Korean routine
- Sourced as the authentic Korean-market formula, not a US reformulation
- Intact Korean-market barcode and batch code on every unit
- Part of Dr Melaxin's dedicated Korean-market lineup
Inside the formula
Inside the formula
Where does this fit in a routine?
As a serum, this is meant to be used at the point in a layered Korean routine where that step normally sits, applied by pressing a few drops into skin after toner and before moisturizer. Using it consistently at that point in the routine is what lets its effect build over repeated use. It is designed to work alongside the other steps around it rather than replace them.
Is this the same formula sold in Korea?
Yes. Dr Melaxin products sold through Korean Pharmacy are sourced as the authentic Korean-market formula, the same version stocked on shelf in Korea, rather than a separate US-facing reformulation many US retailers carry instead. Packaging carries the intact Korean-market barcode and batch code as part of that sourcing. This is the specific gap Dr Melaxin shoppers in the US have been left with since Korean import channels tightened.
How long will one unit last?
How long a serum lasts depends on how much is used per application and how often it is applied, so there is no single number that fits every routine. A smaller, daily-use amount will stretch the unit further than a heavier, occasional application. Checking the fill amount against your own usual per-use amount is the most reliable way to estimate it.
How is this different from the US version of the brand?
Many US retailers carry a reformulated version of Dr Melaxin built to different regulatory or cost targets than the version sold in Korea. Korean Pharmacy sources this specific SKU as the Korean-market formula instead, which is the version Dr Melaxin sells on shelf in Seoul. That is the whole reason a shopper looking for the authentic formula would buy it here rather than from a general US retailer.

37 of 41 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.
- 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.
- Alcohol Denat solvent
- Alcohol Denat. is ethanol with a bitter additive that makes it undrinkable, which is a tax rule rather than a formulation choice. It behaves like alcohol: a fast-evaporating solvent that gives a weightless finish and can feel drying at higher levels.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Glycereth-25 PCA Isostearate emollient
- Glycereth-25 PCA Isostearate is a water-dispersible emollient that softens skin and helps oils and water stay mixed. It reads as light rather than rich on the skin.
25 more explained
- Malt Extract plant extract
- Malt Extract comes from sprouted barley and carries sugars, amino acids and B vitamins. It is used as a conditioning, hydrating extract.
- Momordica Charantia Fruit Extract plant extract
- Bitter melon fruit extract, the yeoju used in Korean tea. It carries flavonoids and saponins and is used as a conditioning extract.
- 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.
- 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.
- Althaea Rosea Flower Extract plant extract
- Althaea Rosea is hollyhock, a mallow relative rich in mucilage. Its flower extract hydrates and leaves a cushioned, slippery feel.
- 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.
- 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.
- Sodium Glycerophosphate humectant
- The sodium salt of glycerin bound to phosphate. It is water soluble, holds water like other polyol salts, and also acts as a mild buffer.
- 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.
- 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.
- Potassium Magnesium Aspartate mineral
- Potassium and magnesium carried on the amino acid aspartic acid, which keeps both minerals soluble in water. It is used as a mineral source and a humectant salt.
- 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.
- Calcium Gluconate (120 Ppm) mineral
- The calcium salt of gluconic acid, a readily water soluble way to bring calcium into a formula. It is used as a mineral source and a mild buffering salt.
- Magnesium Gluconate mineral
- The magnesium salt of gluconic acid, a readily water soluble way to bring magnesium into a formula. It is used as a mineral source and a mild buffering salt.
- Sucrose Palmitate emulsifier
- A sugar ester: table sugar joined to a fatty acid. Sugar esters are mild emulsifiers with a light, silky feel and no detergent sting.
- Theobroma Cacao (cocoa) Seed 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.
- 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.
- 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.
- Polyglutamic Acid humectant
- Polyglutamic Acid comes from fermented soy and holds several times more water than hyaluronic acid for its weight. It forms a light film on the surface, so it is often layered with hyaluronic rather than replacing it.
- 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.
- 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.
- Tremella Fuciformis (mushroom) Extract plant extract
- Tremella Fuciformis is snow mushroom. Its polysaccharide holds even more water than hyaluronic acid for its weight, which is why it appears in hydrating Korean formulas as a plant alternative.
- Collagen Extract protein
- Collagen Extract is a collagen-bearing extract, usually from fish skin or scales. In a formula it works as a humectant and a smoothing film rather than as a source of new collagen.
- Hydrolyzed Elastin protein
- Hydrolyzed Elastin is fragments of elastin, the protein that gives skin its snap back. Like collagen it cannot rebuild the real thing from the outside; it holds water and leaves a smooth film.

How to use
- Use the Cemenrete Calcium Volume Ampoule Plus after toner and before moisturizer, morning and evening.
- Apply using toner, take an appropriate amount of Cemenrete Calcium Ampoule and gently spread it over the entire face for absorption.
- It sits between the toner and the moisturizer, and it is the layer most worth leaving alone for a minute before anything covers it.
- Twice a day, every day. Do not use it as a spot application on one area; an ampoule is a routine step, not a targeted dose.
Worth knowing
- Patch test on a small area before full-face use if you have known sensitivities.
- Discontinue use if irritation, redness, or discomfort develops.
