How it works
The Plum Peptide Booster 2000s is a 50ml serum, used after toner and before moisturizer, morning and evening. The peptide it is built around is Acetyl Hexapeptide-8, named thirty-first on its own ingredient list. The same list carries Niacinamide, Hydrolyzed Sponge and Adenosine, so the peptide is not the only thing on it worth naming. How much of the Acetyl Hexapeptide-8 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 Isntree sells in Korea, Acetyl Hexapeptide-8 and all.

- Cyanocobalamin and Glutathione further down the same list
- Ascorbic Acid and Hydrolyzed Vegetable Protein further down the same list
- Acetyl Hexapeptide-8 named thirty-first on the manufacturer list printed on this page
- Sourced for the Korean market, not a US-shelf reformulation of this serum
Inside the formula
Inside the formula
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 Acetyl Hexapeptide-8 and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Acetyl Hexapeptide-8 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 Acetyl Hexapeptide-8?
Niacinamide, Hydrolyzed Sponge and Adenosine. The order they are printed in on this serum's panel is the order on the box, so you can see where Acetyl Hexapeptide-8 sits relative to them. Further down the same panel: Allantoin, Cyanocobalamin and Glutathione.

Ingredient list read from jolse.com on 10 September 2026.
41 of 42 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.
- 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.
- 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.
- 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.
- 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.
- Olea Europaea (Olive) Fruit Oil emollient
- Olive Fruit Oil is high in oleic acid and plant sterols. It is a rich emollient that suits dry skin and is heavy enough that blemish-prone skin often does not get on with it.
- Ethylhexyl Palmitate emollient
- Ethylhexyl Palmitate is a palm-derived ester used as a light emollient and a solvent for pigment. It gives a smooth, non-greasy slip.
- 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.
- 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.
- Sorbitan Sesquioleate emulsifier
- Sorbitan Sesquioleate is a water-in-oil emulsifier and pigment disperser. Cleansing oils use it so water can be worked into the oil at the rinse.
- 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.
- Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is a pre-neutralised polymer thickener that gels on contact with water and stabilises an emulsion without heat.
29 more explained
- Cetearyl Olivate emulsifier
- Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's 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.
- Vinyl Dimethicone silicone
- Vinyl Dimethicone is a silicone used as a building block of the crosspolymer gels that give a formula its soft, blurring feel.
- Polyisobutene film former
- Polyisobutene is a synthetic polymer that forms a flexible, water-resistant film. It gives gloss and holds a formula in place, which is why it appears in lip products and long-wear textures.
- Sorbitan Olivate emulsifier
- Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
- Hydrolyzed Sponge active
- Hydrolyzed Sponge is processed freshwater sponge, which carries fine silica spicules. In a formula it works as a mild physical exfoliant.
- 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.
- 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.
- 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.
- 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.
- Hydrolyzed Vegetable Protein (10 ppm)* protein
- Hydrolyzed Vegetable Protein is plant protein cut into water-soluble fragments. It forms a light conditioning film that holds water at the surface.
- 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.
- Allium Cepa (Onion) Bulb Extract plant extract
- Onion Bulb Extract carries quercetin and sulphur compounds. Korean formulas use it for the look of blemish marks and uneven tone, and it is the namesake ingredient of the onion skincare line.
- 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.
- 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.
- 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.
- Acetyl Hexapeptide-8 (0.7ppb) peptide
- Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
- Caprylyl/Capryl Glucoside surfactant
- Caprylyl/Capryl Glucoside is a sugar-derived cleansing surfactant. It foams modestly and is mild enough for low-pH cleansers built for reactive skin.
- Sorbitan Oleate emulsifier
- Sorbitan Oleate is an emulsifier for water-in-oil formulas. It keeps a rich cream or a cleansing oil from separating.
- Zea Mays (Corn) Kernel Extract plant extract
- Corn kernel extract, mostly starch-derived sugars with some amino acids. It is used as a conditioning, water-holding extract.
- 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.
- 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.
- 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.
- 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.
- Fructan humectant
- Fructan is a chain of fructose units, usually from chicory. It holds water at the surface and forms a light, conditioning film.
- 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.
- Glutathione antioxidant
- Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
- Ascorbic Acid antioxidant
- Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone.

How to use
- Apply after toner while the skin is damp so a few drops cover the whole face.
- Press it upward across the cheeks and jaw with flat fingertips rather than rubbing.
- Follow with a moisturiser, since a thin booster leaves nothing behind to hold water in.
- Do not expect one week to show anything, because a peptide routine is judged over weeks rather than days.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Acetyl Hexapeptide-8 on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Acetyl Hexapeptide-8 rather than to three changes at once.
