Is the Colla-Juvenation Lift 4 Treatment Essence 130ml sold here the Korean-market formula, not a US reformulation?

Yes. This listing is the release AHC sells for use inside Korea, the same formula Korean shoppers buy off the shelf there. A product with the same name can carry a different ingredient list or a different size in an export version, and we source and list only the Korean one, with that market's barcode and batch code intact on the unit that ships to you.

What is Lactococcus Ferment Lysate doing in this formula?

Lactococcus Ferment Lysate is the first ingredient of real substance on this product's own ingredient list, which puts it at the front of what the formula is built around rather than a trace addition. The rest of the list supports the texture and feel around it, in the concentration order the manufacturer itself declares.

What size does the Colla-Juvenation Lift 4 Treatment Essence 130ml ship in?

It ships at 130ml, the size AHC sells this product at inside Korea. We do not substitute an export format or a US-only size for the Korean one, so what you receive matches what a shopper buys for it in Seoul.

How can I check that my Colla-Juvenation Lift 4 Treatment Essence 130ml is genuine?

AHC sells this exact release inside Korea, and the marker to check is the packaging itself: the Korean-market barcode and printed batch code stay intact on your unit rather than being swapped for an export label.

How it works

This essence opens its ingredient list with Lactococcus Ferment Lysate, ahead of the rest of the formula, which is the clearest sign of what it is built around. Betaine follows further down the list, part of the supporting cast rather than the headline. Adenosine follows further down the list, part of the supporting cast rather than the headline. That order is why AHC positions Colla-Juvenation Lift 4 Treatment Essence 130ml as an essence rather than a general moisturizer or cleanser: the concentration and format are built for the essence step, not for every step in a routine. It belongs in the essence step, after toner and before a heavier serum or moisturizer, morning and evening.

Key benefits

Size: 130ml, the Korean-market fill AHC sells inside Korea for this product.
Led by Lactococcus Ferment Lysate: it sits at the top of this product's own ingredient list, the clearest read of what the formula is built around.
Format: essence, dosed and textured for the essence step rather than a general-purpose step.
Routine slot: after toner and before a heavier serum or moisturizer, morning and evening.
Sourcing: shipped with the Korean-market barcode and batch code intact.
Also on the list: Betaine, one of the supporting ingredients behind the rest of the formula's texture and feel.

Key actives

8Lactococcus Ferment Lysate

Lactococcus Ferment Lysate is a fermented ingredient of the kind Korean formulators favor for a conditioned, less-stripped finish, thought to sit more comfortably on reactive skin than its unfermented form.

All products with Lactococcus Ferment Lysate

12Betaine

Betaine is a gentle humectant and osmolyte that supports comfortable hydration without the tackiness a heavier humectant can leave on the skin's surface.

All products with Betaine

19Adenosine

Adenosine is Korea's own approved wrinkle-care ingredient, included at a functional level to support skin's look of resilience and a smoother surface over consistent use.

All products with Adenosine

21Beta-Glucan

Beta-Glucan is a soothing polysaccharide that supports the look of a calmer, more comfortable skin surface and helps a formula feel less tight after it sets.

All products with Beta-Glucan

27Centella Asiatica Extract

Centella Asiatica Extract is the calming botanical Korean formulators reach for on skin that looks flushed, sensitized, or freshly exfoliated, and it is mild enough to sit underneath stronger actives in the same routine.

42 of 46 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.
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.
Pentylene Glycol humectant: Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
Octyldodeceth-16 emulsifier: An ethoxylated branched fatty alcohol. It emulsifies and also gives a formula a soft, cushioned slip.
C12-14 Pareth-12 emulsifier: C12-14 Pareth-12 is a solubiliser that keeps oils and fragrance in solution so a clear formula stays clear.
Lactococcus Ferment Lysate ferment: Lactococcus Ferment Lysate is a lactic-culture ferment with the bacterial cells broken open, so their contents are in the formula too. It is used as a conditioning ferment in barrier-focused products.
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.
Dioscorea Japonica Root Extract plant extract: Dioscorea Japonica is Japanese wild yam, whose root is naturally slippery with mucilage. Its extract hydrates and leaves a cushioned feel.
Fragrance 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.
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.

30 more explained

Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener: This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
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.
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.
Hydrolyzed Corn Starch absorbent: Hydrolyzed Corn Starch is starch broken into smaller fragments. It gives a silky, powdery slip and absorbs a little oil.
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.
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.
Beta-Glucan polysaccharide: Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
Sucrose humectant: Sucrose is table sugar, used here as a humectant. It draws water into the outer layer of skin and, in a scrub, doubles as the physical grain.
Sodium Polyacrylate thickener: Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
Pvm/Ma Copolymer film former: PVM/MA Copolymer is a film-forming polymer used to hold a formula in place and, in a mask, to give the peel-off film its 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.
Ficus Carica (Fig) Fruit Extract plant extract: Fig Fruit Extract carries fruit sugars, mild acids and a protein-digesting enzyme. It is used as a hydrating extract with a light smoothing effect.
Centella Asiatica Extract plant extract: Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
Ulmus Davidiana Root Extract plant extract: Ulmus Davidiana is Japanese elm, whose inner bark yields a naturally slippery mucilage. Korean formulas use the root extract for that cushioned feel and for the look of reactive skin.
Amaranthus Caudatus Seed Extract plant extract: Amaranth seed extract, carrying squalene, sterols and peptides. It is used as a conditioning extract.
Sodium Benzoate preservative: Sodium Benzoate is a mild preservative that works only in acidic formulas. It is usually paired with potassium sorbate, and the pair is the standard choice where a brand wants no phenoxyethanol.
Sodium Chloride thickener: Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
Ceramide NP barrier lipid: Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
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.
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.
Collagen Amino Acids amino acid: Collagen Amino Acids are collagen broken all the way down to its individual amino acids. At that size they act as humectants, the same job skin's own amino acids do.
Haematococcus Pluvialis Extract antioxidant: An algae extract that is the main natural source of astaxanthin, the deep red carotenoid. It is used as a plant antioxidant and colours a formula orange-red.
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.
Lactic Acid exfoliant: Lactic Acid is a larger AHA than glycolic, so it works nearer the surface and is easier on skin, and it is a humectant as well as an exfoliant. It is the AHA of choice for dry skin.
Oligopeptide-1 peptide: Oligopeptide-1 is a short synthetic peptide. Oligo means the chain is short without the name fixing its length, which is why oligopeptides appear in blends where several sequences work together.
Aluminum/Magnesium Hydroxide Stearate dispersant: A mineral soap used to suspend powders and thicken an oil phase, which is what stops pigment settling to the bottom of a bottle.
Hexapeptide-11 peptide: Hexapeptide-11 is a yeast-derived six-amino-acid peptide used for the look of resilience and firmness.
Acetyl Tetrapeptide-9 peptide: Acetyl Tetrapeptide-9 is a four-amino-acid peptide used for the look of firmness and density. It is most often supplied alongside acetyl tetrapeptide-11.
