How it works
A gommage gel does not scrub: it gathers on the skin as it is massaged and lifts loose surface cells away with it when it is rinsed. This one carries papain and lactobionic acid, with Rosa damascena flower water and lavender flower water in the base and niacinamide on the same list. It goes on after cleansing in the evening, on damp skin, and it is rinsed off before the rest of the routine. Skin that looks rough and dull but does not want an acid every evening is the case this format suits. Two or three evenings a week, and not on the same evening as an acid or a retinoid.
How to use
- Use the Low pH Goodnight Soft Peeling Gel in the evening, after cleansing, on skin that is still damp.
- A coin-sized amount, massaged over the face in light circles for under a minute while the gel gathers.
- Rinse it off, then carry on with toner, serum and moisturizer the same evening.
- Two or three evenings a week. Do not press hard or keep going past a minute; a gel like this lifts rather than scrubs.
COSRX Low pH Goodnight Soft Peeling Gel
What does this peeling gel actually remove, dead skin or a physical layer?
It works with lactobionic acid, a gentle PHA, and papain, a fruit enzyme, both listed mid-formula, rather than with abrasive scrub particles. Both work by loosening dead surface cells chemically or enzymatically, and any visible rolling texture during use is from that loosened debris mixing with the gel, not from scrubbing.
Is this exfoliant gentle enough for nightly use?
Lactobionic acid is a PHA, generally considered the gentlest acid family, and papain works enzymatically rather than through a stronger acid concentration. Combined with niacinamide, hyaluronic acid and several ferment filtrates for support, the formula is built for the 'Goodnight' frequency the name suggests, though sensitive skin should still start a few nights a week.
What are the ferment ingredients in this gel for?
Lactobacillus and soybean ferment extract, plus a separate lactobacillus and rice ferment, appear toward the end of the list. Fermented ingredients like these are typically included in Korean formulas for their soothing and skin-conditioning reputation, supporting the exfoliating acids rather than exfoliating themselves.
Does this contain fragrance or rose water?
Rosa damascena flower water appears near the top of the list, giving both a light floral note and a soothing, hydrating base. The list does not separately declare fragrance or parfum.
Is niacinamide doing anything meaningful in an exfoliating gel like this?
Niacinamide sits roughly midway through the list, after the acid and enzyme portion. In a leave-on gel like this it contributes brightening support alongside the exfoliation, rather than requiring the acid to do all the work of improving skin tone and texture.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

24 of 25 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.
- Cellulose absorbent
- Cellulose is plant fibre. In a formula it thickens, absorbs oil and, in a sheet mask, is often the fabric itself.
- 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.
- Rosa Damascena Flower Water plant extract
- Rosa Damascena Flower Water is the water left from distilling rose petals. It is used in place of plain water as a base and carries the scent and trace compounds of the distillation.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Maltodextrin film former
- Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
12 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.
- 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.
- 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.
- Lactobionic Acid exfoliant
- Lactobionic Acid is a polyhydroxy acid, the gentlest of the acid families because the molecule is large and slow to travel. It is also a strong humectant.
- Papain exfoliant
- Papain is a protein-cutting enzyme from papaya. Enzyme exfoliants act on protein rather than on the bonds an acid targets, and they need water to work, which is why they suit powder washes.
- 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.
- Lactobacillus/Soybean Ferment Extract ferment
- This is soybean fermented by lactobacillus. The fermentation breaks soy proteins into smaller pieces, which is what makes the extract easier for a formula to carry.
- 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.
- Sodium Metabisulfite antioxidant
- Sodium Metabisulfite is a sulfite salt used to stop a formula oxidising and browning. It is the ingredient that keeps a vitamin C or plant-extract formula from going amber.
- Lactobacillus/Rice Ferment ferment
- Rice fermented with lactobacillus, the same bacteria behind kimchi and makgeolli. Fermentation breaks the rice starch into smaller sugars and amino acids that hold water.
- Camellia Japonica Flower Extract plant extract
- Camellia Japonica Flower Extract comes from the flower of the Korean camellia. It is used as a conditioning, hydrating extract.
