Where does this foam cleanser go in my routine?

As your first step, morning and evening, on a face already wet with lukewarm water. Nothing goes under it: this foam cleanser is the step everything else in the routine lands on top of. 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.

What else is on the list besides Allantoin?

Portulaca Oleracea Extract, Oryza Sativa (Rice) Bran Extract and Aspalathus Linearis (Rooibos) Extract. The order they are printed in on this foam cleanser's panel is the order on the box, so you can see where Allantoin sits relative to them. Further down the same panel: Glycyrrhiza Glabra (Licorice) Root Extract and Trehalose.

Key actives

13Allantoinactive

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. On this foam cleanser's own ingredient list it is named thirteenth.

All products with Allantoin

15Portulaca Oleracea Extractplant extract

Portulaca Oleracea is purslane. Its extract is unusually high in omega-3 fatty acids and antioxidants for a plant, and Korean formulas use it for the look of reddened, reactive skin. The panel names it fifteenth on this foam cleanser's list, beside Allantoin.

16Oryza Sativa (Rice) Bran Extractplant extract

Rice bran extract, from the outer layer milled off white rice. Bran is the richest part of the grain, carrying ferulic acid, vitamin E and phytic acid. It is named sixteenth on this foam cleanser's list, alongside Allantoin.

20Aspalathus Linearis (Rooibos) Extractplant extract

Rooibos extract, from the South African red bush. It carries aspalathin and other flavonoids and no caffeine, and it is used as a plant antioxidant. It is named twentieth on this foam cleanser's list, alongside Allantoin.

21Glycyrrhiza Glabra (Licorice) Root Extractplant extract

Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives. It is named twenty-first on this foam cleanser's list, alongside Allantoin.

19 of 22 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.
Disodium Cocoamphodiacetate surfactant: Disodium Cocoamphodiacetate is a very mild coconut-derived surfactant used in cleansers for reactive skin and around the eyes.
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.
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.
Potassium Cocoyl Glycinate surfactant: Potassium Cocoyl Glycinate is a coconut-and-glycine surfactant used in low-pH cleansers. It foams well and rinses without the squeaky tightness a soap leaves.
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.
Melaleuca Alternifolia (Tea Tree) Leaf Water plant extract: Tea Tree Leaf Water is the distillate, used in place of plain water as a base. It carries a trace of the plant's aroma and none of the essential oil's strength.
Polyglyceryl-4 Caprate emulsifier: Polyglyceryl-4 Caprate is a mild sugar-derived solubiliser used to dissolve fragrance and oil into watery formulas.
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.
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.
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.

Portulaca Oleracea Extract plant extract: Portulaca Oleracea is purslane. Its extract is unusually high in omega-3 fatty acids and antioxidants for a plant, and Korean formulas use it for the look of reddened, reactive skin.
Oryza Sativa (Rice) Bran Extract plant extract: Rice bran extract, from the outer layer milled off white rice. Bran is the richest part of the grain, carrying ferulic acid, vitamin E and phytic acid.
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.
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.
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.
Aspalathus Linearis Extract plant extract: Rooibos extract, from the South African red bush. It carries aspalathin and other flavonoids and no caffeine, and it is used as a plant antioxidant.
Glycyrrhiza Glabra (Licorice) Root Extract plant extract: Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.

How it works

The Centella Bubble Cleansing Foam is a 150ml foam cleanser, used as your first step, morning and evening, on a face already wet with lukewarm water. The active it is built around is Allantoin, named thirteenth on its own ingredient list. The same list carries Portulaca Oleracea Extract, Oryza Sativa (Rice) Bran Extract and Aspalathus Linearis (Rooibos) 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 foam cleanser format rather than by the list alone. IUNIK sells this Allantoin foam cleanser in Korea, and this is that version.

How to use

Work a small amount into a lather with water, massage over damp skin for 30 to 60 seconds, then rinse thoroughly. Use once or twice daily as the first step of the routine.

Worth knowing

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

What professionals say

Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

It is said to be rich in vitamins, minerals and amino acids, including skin nourishers like B vitamins, vitamin E and inositol.
