Key actives
11Lithospermum Erythrorhizon Root Extract
Purple gromwell root, long used in Korean and Chinese herbal practice. The root is deep red-purple, so it colours a formula, and it is used for the look of reactive skin.
14Adenosine
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.
15Collagen
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.
18Theobroma Cacao (cocoa) Extract
Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
Is the Renewing Ampoule 30ml sold here YUNJAC's Korean-market formula?
Yes. What ships is YUNJAC's release for the Korean market: the formula and packaging sold in Korea, with the Korean-market barcode and batch code intact on the box rather than swapped for an export or US-retail label.
Where does the Renewing Ampoule 30ml go in a routine?
It takes after toner and before moisturizer. That placement follows from what a serum is, not from anything unusual about this specific unit. A serum in this format is built to carry a concentrated dose of its named actives in a light enough base that it absorbs before the next step goes on, so moving it earlier or later in a routine works against the format rather than with it.
Who is the Renewing Ampoule 30ml best suited for?
Normal, Combination, Dry skin types get the most straightforward use from a serum in this format. Patch test first, as with any new product entering a routine, and give it a week or two before judging the fit.
What format is the Renewing Ampoule 30ml, and how does that change how it is used?
It is a serum, and the format sets the routine rules that come with it: Apply to clean, toned skin, pressing in gently before the next step. YUNJAC builds this one to match that format rather than departing from it.
How does buying the Renewing Ampoule 30ml here compare with a US retailer carrying the same name?
A US listing under the same product name can be a reformulated export version and rarely states which one it is selling. What we carry is the Korean-market YUNJAC release, identified by its intact Korean barcode and batch code on the box rather than a relabeled export carton, so the unit you get matches what is sold on shelf in Korea.

Ingredient list read from yunjac.com on 30 August 2026.
25 of 26 explained
- Water (aqua) 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.
- Polyglycerin-3 humectant
- Polyglycerin-3 is a short chain of glycerin units used as a gentler, less sticky humectant. It also helps oils and water stay 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Lithospermum Erythrorhizon Root Extract plant extract
- Purple gromwell root, long used in Korean and Chinese herbal practice. The root is deep red-purple, so it colours a formula, and it is used for the look of reactive skin.
- PPG-13-Decyltetradeceth-24 emulsifier
- PPG-13-Decyltetradeceth-24 is a solubiliser used to hold oils and fragrance in a clear water-based formula.
13 more explained
- 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.
- 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.
- Theobroma Cacao (cocoa) 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.
- 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.
- 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.
- 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.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- Geraniol fragrance component
- Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.

How it works
Collagen is named on the ingredient panel on this ampoule. 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. On this panel it sits alongside Lithospermum Erythrorhizon Root Extract, Adenosine and Theobroma Cacao (cocoa) Extract. Purple gromwell root, long used in Korean and Chinese herbal practice. The root is deep red-purple, so it colours a formula, and it is used for the look of reactive skin.
