CNP
Laboratory Invisible Peeling Booster 100ml
Gluconolactone is second on this booster's own list, ahead of panthenol, allantoin, urea and beta-glucan, so the 100 ml bottle takes surface build-up off two or three nights a week without the sting of a stronger acid.

How it works
The Laboratory Invisible Peeling Booster is a 100ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Allantoin, named tenth on its own ingredient list. The same list carries Gluconolactone, Beta-Glucan and Cordyceps Sinensis Extract, so the active is not the only thing on it worth naming. How much of the Allantoin 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 CNP sells in Korea, Allantoin and all.
Key benefits
- Allantoin, the active this serum is built around
- Gluconolactone on the same list, an exfoliant
- Beta-Glucan on the same list, a polysaccharide
- Cordyceps Sinensis Extract on the same list, a plant extract
- Panthenol and Polyglutamic Acid further down the same list
- Fructose and Sodium Hyaluronate further down the same list
How to use
- Use it after cleansing, before toner, 2 to 3 times a week rather than daily. 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 Allantoin and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Allantoin 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.
Does this serum contain fragrance?
Yes. The ingredient list names Citronellol and Geraniol. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this serum is not the one.
What else is on the list besides Allantoin?
Gluconolactone, Beta-Glucan and Cordyceps Sinensis Extract. The order they are printed in on this serum's panel is the order on the box, so you can see where Allantoin sits relative to them. Further down the same panel: Arginine, Panthenol and Polyglutamic Acid.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

34 of 36 explained
- Purified 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.
- Gluconolactone exfoliant
- Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
- 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.
- 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.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- 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.
- 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.
- 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.
- 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.
- 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.
- Polyglyceryl-10 Myristate emulsifier
- Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.
22 more explained
- Cordyceps Sinensis Extract plant extract
- Cordyceps extract, from a fungus that grows on insect larvae. It carries polysaccharides and amino acids and is used as a conditioning extract.
- Polyglutamic Acid humectant
- Polyglutamic Acid comes from fermented soy and holds several times more water than hyaluronic acid for its weight. It forms a light film on the surface, so it is often layered with hyaluronic rather than replacing it.
- 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.
- Sodium Hydroxide pH adjuster
- Sodium Hydroxide is a strong base used in traces to bring an acidic formula up to skin-friendly pH. None of it remains as itself once the formula is neutralised.
- 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.
- Urea humectant
- Urea is one of the substances skin makes to hold its own water, part of the natural moisturising factor. At low levels it hydrates; at high levels it also softens hard, thickened skin.
- 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.
- 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.
- Pelargonium Graveolens Flower Oil fragrance component
- Pelargonium Graveolens is rose geranium. Its flower oil is an essential oil used to scent a formula, carrying citronellol and geraniol.
- 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.
- Sodium Lactate humectant
- Sodium Lactate is the salt of lactic acid and one of the components of skin's own natural moisturising factor. At the levels used here it is a humectant and buffer rather than an exfoliant.
- Sodium PCA humectant
- Sodium PCA is one of the substances skin makes for itself to hold water, part of what dermatology calls the natural moisturising factor. Added to a formula it is a strong humectant that suits skin that dehydrates quickly.
- 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.
- 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.
- Sodium Citrate pH adjuster
- Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.
- 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.
- 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.
- 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.
- Potassium Sorbate preservative
- Potassium Sorbate is a preservative that holds off yeast and mould in acidic formulas. It is almost always used with sodium benzoate, because neither covers the whole range of microbes alone.
- 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.
- 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.

Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Allantoin on the list.
- This list names Citronellol and Geraniol, so skip it if fragrance components are something you avoid.
- Citric Acid and Gluconolactone on this list makes this serum an exfoliating step, so do not stack it with another one on the same night.
