How to use
- Use the PURIFYING CENTELLA SOOTHING MASK after toner, in place of your serum step, in the evening.
- Apply one mask to clean, dry skin and leave on for 10 to 20 minutes. Remove the mask and gently massage the remaining essence into the skin. No rinsing is needed.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Does this product contain added fragrance?
No. Neither fragrance nor parfum appears on the ingredient list for IWLT PURIFYING CENTELLA SOOTHING MASK 25ml x 6ea. Those are the two names a cosmetic label uses for an added scent blend, so a formula carrying one would name it. The full list is printed in the Ingredients section of this page.
Does this product contain essential oils?
Yes. The ingredient list for IWLT PURIFYING CENTELLA SOOTHING MASK 25ml x 6ea includes Citrus Aurantium Bergamia (Bergamot) Fruit Oil and Rosmarinus Officinalis (Rosemary) Leaf Oil. Aromatic plant oils are listed under their botanical name rather than as fragrance, so they are named separately from any fragrance or parfum entry.
Are any declarable fragrance allergens listed?
Yes. Limonene and Linalool appear on the ingredient list for IWLT PURIFYING CENTELLA SOOTHING MASK 25ml x 6ea. These belong to the 26 fragrance components that EU cosmetic labelling requires to be named individually rather than folded into a fragrance entry.
Does this product contain denatured or SD alcohol?
No. The ingredient list for IWLT PURIFYING CENTELLA SOOTHING MASK 25ml x 6ea names no denatured alcohol, SD alcohol or ethanol. Fatty alcohols such as cetyl and cetearyl alcohol are a different class of ingredient, used as emollients and thickeners, and are not counted here.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

32 of 32 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.
- 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.
- 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.
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
- 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.
- 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.
- Caffeine active
- Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on 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.
- 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.
20 more explained
- 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.
- 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.
- 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.
- 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.
- 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.
- Althaea Rosea Flower Extract plant extract
- Althaea Rosea is hollyhock, a mallow relative rich in mucilage. Its flower extract hydrates and leaves a cushioned, slippery feel.
- Hamamelis Virginiana (Witch Hazel) Water plant extract
- Witch hazel distillate, used in place of part of the plain water in a formula. It is much more dilute than the extract, and commercial witch hazel water often carries alcohol.
- Citrus Aurantium Bergamia (Bergamot) Fruit Oil fragrance component
- Bergamot Fruit Oil is a citrus essential oil and the top note of eau de cologne. It scents a formula; citrus oils are the aromatic class most likely to bother reactive 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.
- Pyrus Malus (Apple) Fruit Extract plant extract
- Apple fruit extract, carrying malic acid, sugars and polyphenols. It is used as a conditioning extract with a mild acid character.
- Rosmarinus Officinalis (Rosemary) Leaf Oil fragrance component
- Rosemary Leaf Oil is an essential oil carrying camphor and cineole. It scents a formula and is a stronger aromatic than most.
- 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.
- Moringa Oleifera Seed Extract plant extract
- Moringa seed extract. The seed is best known for its oil and for the cationic peptides used to clarify water, and in a formula the extract is a conditioning botanical.
- Caprylic/Capric Triglyceride emollient
- Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
- Pistacia Lentiscus (Mastic) Gum plant extract
- Mastic gum, the resin of a Mediterranean shrub. It forms a film and carries its own resinous scent.
- Hydrogenated Lecithin emulsifier
- Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
- Spiraea Ulmaria Extract plant extract
- Meadowsweet extract. The plant carries salicylates and tannins, so it has an astringent character, and it is the botanical the name aspirin was originally taken from.
- Phenethyl Alcohol preservative booster
- Phenethyl Alcohol is an aromatic alcohol with a faint rose scent. It works as a preservative booster and a light solvent, and it is common in formulas built without traditional preservatives.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.
