How it works
The Exosome Collagen EX Serum is a 40ml serum, used after toner and before moisturizer, morning and evening. The protein it is built around is Hydrolyzed Collagen, named twenty-second on its own ingredient list. The same list carries Allantoin, Dipotassium Glycyrrhizate and Asiaticoside, so the protein is not the only thing on it worth naming. How much of the Hydrolyzed Collagen 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 APLB sells in Korea, Hydrolyzed Collagen and all.
Key benefits
- Hydrolyzed Collagen, the protein this serum is built around
- Allantoin, Dipotassium Glycyrrhizate, Asiaticoside and Madecassic Acid on the same list, actives
- Asiatic Acid and Saccharomyces Ferment further down the same list
- Inulin and Beta-Glucan further down the same list
- Hydrolyzed Collagen named twenty-second on the manufacturer list printed on this page
- Sourced for the Korean market, not a US-shelf reformulation of this serum
How to use
- Apply after toner and before moisturizer. Pat or smooth it over a cleansed face and let it absorb before the next step, AM and PM.
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 Hydrolyzed Collagen and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Hydrolyzed Collagen 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 Hydrolyzed Collagen?
Allantoin, Dipotassium Glycyrrhizate and Asiaticoside. The order they are printed in on this serum's panel is the order on the box, so you can see where Hydrolyzed Collagen sits relative to them. Further down the same panel: Madecassic Acid, Asiatic Acid and Saccharomyces Ferment.

39 of 39 explained
- Centella Asiatica Leaf Water plant extract
- Centella Asiatica Leaf Water is the distilled water of the centella leaf, used in place of plain water as a formula base. It is far more dilute than the extract, so it sets the base rather than supplying the actives.
- 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.
- 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.
- 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.
- 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.
- 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.
- Panthenol humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- 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.
- Sodium Polyacryloyldimethyl Taurate thickener
- Sodium Polyacryloyldimethyl Taurate is a polymer thickener that holds a gel stable even with a lot of salt or acid in the formula.
- 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.
- 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.
27 more explained
- 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.
- Citric Acid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- 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.
- Inulin polysaccharide
- Inulin is a plant fructan, most often from chicory root. It holds water and, in a formula, feeds the beneficial bacteria on the surface.
- 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.
- Cellulose absorbent
- Cellulose is plant fibre. In a formula it thickens, absorbs oil and, in a sheet mask, is often the fabric itself.
- 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.
- 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.
- 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.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- 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.
- 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.
- C12-14 Alketh-12 emulsifier
- C12-14 Alketh-12 is a solubiliser used to keep oils and fragrance dissolved in a water-based formula.
- Camellia Japonica Leaf Extract plant extract
- The leaf extract of the Korean camellia, the same plant as the seed oil pressed on Jeju. It is used as a conditioning antioxidant extract.
- 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.
- 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.
- 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.
- 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.
- Melaleuca Alternifolia (Tea Tree) Leaf Extract plant extract
- Tea Tree Leaf Extract is the water-based extract rather than the essential oil, so it is far milder and much less aromatic. It is used in formulas for blemish-prone skin.
- Hippophae Rhamnoides Fruit Extract plant extract
- Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract.
- 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.
- Nelumbium Speciosum Flower Extract plant extract
- Lotus flower extract, from the same sacred lotus as the leaf. It carries flavonoids and sugars and is used as a conditioning, hydrating extract.
- Artemisia Annua Extract plant extract
- Artemisia Annua is sweet wormwood, a mugwort relative. Its extract is used in Korean formulas for the look of reactive skin.
- Oryza Sativa (Rice) Extract plant extract
- Rice Extract is the anchor of the Korean rice-skincare category. It carries starches, amino acids and ferulic acid, and it is used for the look of dullness and for a soft, blurred finish.
- Saccharomyces Ferment ferment
- Saccharomyces Ferment is a brewer's yeast ferment. It supplies amino acids, sugars and B vitamins and is used as a conditioning, hydrating ferment.
- Solanum Melongena (Eggplant) Fruit Extract plant extract
- Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.

Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Hydrolyzed Collagen on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Hydrolyzed Collagen rather than to three changes at once.
