What does the Collagen Jelly Cream 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 Collagen Jelly Cream?

Use this gel cream as the last step of a routine, over serum. To apply, scoop a small amount and press over the face and neck as the last step of the routine. 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 Collagen Jelly Cream the same formula sold in Korea, or a US version?

This Collagen Jelly Cream 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 Collagen Jelly Cream with other actives in my routine?

Yes, as long as it is used in its own step, the last step of a routine, over serum, 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 Collagen Jelly Cream suited for?

It suits most skin types looking for last step of routine, over serum rather than a single acute problem. It comes in a 50ml format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

Key actives

9NiacinamideTone and texture

Niacinamide sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. It is an ingredient chosen for tone and texture: a form of vitamin B3 that supports a more even-looking tone and a smoother surface texture with regular use, and layers comfortably under most other actives.

13CollagenPlumping feel

Collagen sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for plumping feel: included for the cushioned, bouncy surface feel it gives a formula rather than for any claim about the skin's own collagen.

14Hydrolyzed CollagenPlumping feel

Hydrolyzed Collagen sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for plumping feel: collagen broken into smaller fragments so it spreads easily and leaves a smoother, more cushioned surface feel.

17Soluble CollagenPlumping feel

Soluble Collagen sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for plumping feel: a water-soluble collagen fragment that sits on the skin's surface and gives an immediate plumping, cushioned feel without any claim about the skin's own collagen underneath.

35AdenosineFirming look

Adenosine sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for firming look: a nucleoside included for its reputation in smoothing the look of fine expression lines, one of the more established anti-aging ingredients in Korean formulation.

48 of 48 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.
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.
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.
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.
Diethoxyethyl Succinate solvent: Diethoxyethyl Succinate is a solvent that helps water-resistant actives spread and sink in evenly. It also leaves a light, silky feel.
Ethoxydiglycol solvent: Ethoxydiglycol is a solvent that keeps stubborn actives in solution, most often vitamin C or an acid, and helps them spread evenly instead of settling out.
Ammonium Acryloyldimethyltaurate/Beheneth-25 Methacrylate Crosspolymer thickener: A gelling polymer that thickens and emulsifies at once. It gives the light, non-sticky gel texture Korean essences are known for.
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.
Trehalose humectant: Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
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.
Chlorella Vulgaris Extract plant extract: Chlorella Vulgaris is a freshwater green algae. Its extract carries proteins, chlorophyll and amino acids and is used as a conditioning ingredient.

36 more explained

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.
Hydrolyzed Collagen protein: Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
Cynanchum Atratum Extract plant extract: Cynanchum Atratum is a root used in Korean traditional practice. Its extract is used as a conditioning plant extract in formulas for reactive skin.
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.
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.
Allium Sativum (Garlic) Bulb Extract plant extract: Garlic bulb extract. It carries sulfur compounds and turns up in scalp formulas more often than in facial ones.
Avena Sativa (Oat) Kernel Extract plant extract: Oat Kernel Extract carries beta-glucan and avenanthramides, and it is one of the most reliably tolerated ingredients in skincare. It is used for the look of reddened, itchy-feeling skin.
Bertholletia Excelsa Seed Extract plant extract: Brazil nut seed extract, carrying selenium, sterols and fatty acids. It is used as a conditioning extract.
Brassica Oleracea Italica (Broccoli) Extract plant extract: Broccoli extract, carrying sulforaphane and vitamin C. It is used as a plant antioxidant.
Camellia Sinensis Seed Extract plant extract: Green tea seed extract, from the seed rather than the leaf, so it carries saponins and sterols instead of catechins. It is used as a conditioning extract.
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.
Solanum Lycopersicum (Tomato) Fruit Extract plant extract: Tomato fruit extract, a source of lycopene and other carotenoids. It is used as a plant antioxidant extract.
Spinacia Oleracea (Spinach) Leaf Extract plant extract: Spinach leaf extract, carrying lutein, flavonoids and minerals. It is used as a plant antioxidant.
Vaccinium Angustifolium (Blueberry) Fruit Extract plant extract: Lowbush blueberry fruit extract, high in anthocyanins. Berry extracts are used as plant antioxidants and can tint a formula.
Wine Extract plant extract: Wine extract, carrying grape polyphenols including resveratrol. It is used as a plant antioxidant.
Polyglyceryl-10 Isostearate emulsifier: A ten-unit polyglycerin ester, very water-loving, used as a mild emulsifier and solubiliser in place of a PEG.
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.
Glucose humectant: Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
Polyglyceryl-10 Oleate emulsifier: Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
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.
Fructooligosaccharides humectant: Fructooligosaccharides are short fructose chains used as humectants and as food for the skin's own resident microbes.
Fructose humectant: Fructose is a simple sugar used as a light humectant. It holds water in the outer layer and often arrives as part of a fruit or honey extract.
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 Phytate chelator: Sodium Phytate is a rice-derived chelator used in place of EDTA. It ties up trace metals so the formula stays stable and its colour and scent hold.
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.
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.
Pullulan film former: Pullulan is a fermentation-derived polysaccharide that dries to a tight film, which is why it produces a temporary, visible tightening feel on the skin.
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.
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.
Squalane emollient: Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
Soluble Proteoglycan protein: A proteoglycan is a protein with sugar chains attached, the same architecture as the water-holding molecules in cartilage and skin. Made soluble, it is used as a humectant and conditioning protein.
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.
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.
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.
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.
Fragrance (Parfum) fragrance: Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.

How it works

Medicube Collagen Jelly Cream is a gel cream built for the last step of a routine, over serum. Its ingredient list leads with Niacinamide, Collagen, and Hydrolyzed Collagen, 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 last step of a routine, over serum, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the Collagen Jelly Cream line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

How to use

Use it as the final leave on step so nothing thinner sits above it.
Take a small scoop and press it over the face rather than rubbing it in circles.
Add a second thin layer only where the skin feels tight instead of one heavy coat.
Do not work a jelly texture around with force, since that is what makes it ball up.

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.
