Key benefits
- Centella Asiatica Extract sits near the top on this product's own ingredient list, a cica botanical used to calm visible redness after exfoliation or sun exposure.
- A multifunctional glycol that carries moisture and helps preserve the formula, and Butylene Glycol is right there in this product's ingredient list, near the top.
- On this formula's own list, Panthenol shows up in the first half. It is a barrier-supporting provitamin that eases surface roughness.
Key actives
8Panthenol
A comfort humectant on this list that keeps a twice daily serum from reading as drying on an already unhappy face.
12Sodium Hyaluronate
A humectant that holds water at the surface, giving a thin serum enough cushion to be worn without a heavy cream in summer.
18Asiaticoside
A second fraction from the same botanical family on this list, which is why the calming side of the serum reads as deliberate.
19Asiatic Acid
A third fraction from the same family on this list, the mark of a formula built on the isolated pieces rather than the raw extract alone.
21Madecassoside
A calming botanical fraction high on this list, the best established of its group in Korean formulas aimed at skin that reddens.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
Who is this serum for?
Skin that reddens easily, whether by nature or after a strong product, cold weather or too much exfoliation. It is a light daily step rather than an occasional recovery product. You judge it on whether the face reads less pink half an hour after applying it and over the following weeks.
Where does it go in my routine?
After the toner and before the cream, morning and night. It is thin, so it goes on before anything heavier and lands on damp skin. In the morning your sunscreen is still the last thing on, once the cream has had a minute to settle.
Serum or cream from this range?
The serum if you already have a moisturizer you like and want to add soothing without changing your cream. The cream if you want one product doing both the calming and the sealing. Using both is fine and is what people with genuinely reactive skin often end up doing in winter.
Is it enough on its own?
For oily skin in warm weather, often yes. Everyone else should seal it with a cream, since a serum is mostly water and dries off within the hour with nothing over it. If a full cream feels heavy, use a thin layer of a lighter one rather than skipping the step.
Is this the Korean-market formula?
Yes. This is the Original Korean Formula size, the same one sold on Korean shelves.

19 of 21 explained
- 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.
- 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.
- 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.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- 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.
- Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is the thickener behind most gel-cream textures. It builds a soft, bouncy gel that collapses to a light fluid as it is rubbed in.
- 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.
- 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.
- 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.
- 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.
7 more explained
- 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.
- 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.
- Pinus Pinaster Bark Extract plant extract
- Maritime pine bark extract, the source of the proanthocyanidins sold under the pine bark name. It is used as a plant antioxidant.
- 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.
- 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.
- 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.
- Madecassoside active
- Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.

How it works
A serum is the thin concentrated step, so a calming serum is the right shape when you want the soothing work without adding weight to the routine. It goes on before the cream and does its part while the surface is still damp, which is when a thin layer spreads evenly rather than dragging. Because it is light, it can be used morning and night and still sit under sunscreen without changing how that layer feels. That is the difference from a calming cream, which does the sealing job too and cannot be layered under much. What you can judge is whether the face reads less pink half an hour after you apply it.
How to use
- Apply after the toner while the skin is still damp, so a small dose covers the face in one pass.
- Press it in with the flats of the fingers rather than rubbing it around in circles.
- Follow with a cream to hold it in place, then sunscreen as the final morning step.
- Do not stack it with an exfoliating step in the same sitting, since the reason you bought it is that the skin already reacts.
Worth knowing
- Patch test along the jaw for two days first, since this is a twice daily leave-on serum.
- Cut back to once a day if the skin feels tight, rather than adding a richer cream over the top.
