How it works
The Yam Root Vegan Milk Toner is a 200ml toner, used straight after cleansing, morning and evening, while the face is still damp. The barrier lipid it is built around is Ceramide NP, named thirteenth on its own ingredient list. The same list carries Cholesterol, Deoxyphytantriyl Palmitamide MEA and Hibiscus Esculentus Fruit Extract, so the barrier lipid is not the only thing on it worth naming. How much of the Ceramide NP stays on the skin, and for how long, is decided by the toner format rather than by the list alone. This is the Original Korean Formula, the toner Isntree sells in Korea, Ceramide NP and all.

Isntree Yam Root Vegan Milk Toner
Where does this toner go in my routine?
Straight after cleansing, morning and evening, while the face is still damp. Anything thinner than a toner 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 Ceramide NP and not three changes at once.
Is this the Korean-market toner or a US version?
The Korean-market one, Ceramide NP and all. We match this toner to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Ceramide NP?
Cholesterol, Deoxyphytantriyl Palmitamide MEA and Hibiscus Esculentus Fruit Extract. The order they are printed in on this toner's panel is the order on the box, so you can see where Ceramide NP sits relative to them. Further down the same panel: Nelumbo Nucifera Root Extract, Undaria Pinnatifida Extract and Laminaria Japonica Extract.

34 of 35 explained
- 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.
- 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.
- 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.
- 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.
- Sunflower Seed Oil emollient
- Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
- Limnanthes Alba (Meadowfoam) Seed Oil emollient
- Meadowfoam Seed Oil is over 95 percent long-chain fatty acids, which makes it exceptionally stable against going rancid. It is an emollient that leaves a soft, sealed feel.
- Macadamia Ternifolia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
- Argania Spinosa Kernel Oil emollient
- Argan Oil is pressed from the argan kernel and is rich in oleic and linoleic acids plus vitamin E. It is a medium-weight emollient that absorbs reasonably fast.
- Inulin Lauryl Carbamate emulsifier
- A chicory-sugar polymer with a fatty chain attached. It stabilises an emulsion by forming a film at the oil and water boundary rather than acting as a classic surfactant.
- Sodium Surfactin surfactant
- A biosurfactant produced by Bacillus fermentation. It lowers surface tension at very low concentrations, so a formula needs very little of it.
- Ceramide NP barrier lipid
- Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
22 more explained
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
- Stearic Acid fatty acid
- Stearic Acid is a saturated fatty acid from plant fats, and one of the three lipid classes skin's own barrier is built from. In a formula it thickens, stabilises the emulsion and can be turned into a soap-style cleanser by adding a base.
- 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.
- Hibiscus Esculentus Fruit Extract plant extract
- Hibiscus Esculentus is okra, whose fruit is thick with mucilage. Its extract hydrates and gives a cushioned, slippery feel.
- Nelumbo Nucifera Root Extract plant extract
- Lotus root extract. The root is starchy and mucilaginous, so the extract hydrates and leaves a soft, cushioned feel.
- Undaria Pinnatifida Extract plant extract
- Extract of the brown seaweed Korean cooking calls miyeok. It carries fucoidan and alginates, both strong water-holding polysaccharides.
- Laminaria Japonica Extract plant extract
- Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
- Prunus Amygdalus Dulcis (Sweet Almond) Seed Extract plant extract
- Sweet almond seed extract, the water-soluble fraction rather than the pressed oil. It carries proteins and sugars and is used as a conditioning extract.
- Avena Sativa (Oat) Meal Extract plant extract
- Oatmeal extract, carrying the beta-glucan, starch and avenanthramides oats are used for. It is one of the standard additions to a formula built for easily bothered skin.
- Malt Extract plant extract
- Malt Extract comes from sprouted barley and carries sugars, amino acids and B vitamins. It is used as a conditioning, hydrating extract.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Oryza Sativa (Rice) Extract plant extract
- Rice Extract is the anchor of the Korean rice-skincare category. It carries starches, amino acids and ferulic acid, and it is used for the look of dullness and for a soft, blurred finish.
- Sodium Polyacrylate thickener
- Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
- 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.
- Deoxyphytantriyl Palmitamide MEA barrier lipid
- A synthetic ceramide-like lipid. It sits in the spaces between skin cells the way skin's own ceramides do and helps hold water in.
- Glycine Max (Soybean) Seed Extract plant extract
- Soybean Seed Extract carries isoflavones, plant sterols and soy proteins. It is used as a conditioning antioxidant extract.
- Cocos Nucifera (Coconut) Fruit Extract plant extract
- Coconut fruit extract, carrying sugars, amino acids and minerals from the flesh and water. It is a conditioning, water-holding extract.

How to use
- Use the Yam Root Vegan Milk Toner straight after cleansing, morning and evening, while the face is still damp.
- Pour a coin-sized pool into your palms and press it over the face in two passes rather than dragging it around with a cotton pad.
- It goes on before serum and moisturizer, and the damp layer it leaves is what the step above it holds on to.
- Twice a day, every day. Do not let it dry down completely before the next layer goes on, or you lose the reason for applying it to damp skin.
Worth knowing
- Patch test this toner on a small area and wait a day before using it more widely, especially with Ceramide NP on the list.
- Introduce this toner on its own for the first week, so anything your skin does is traceable to the Ceramide NP rather than to three changes at once.
