Who is the True Mushroom LX Treatment Toner 120ml suited for?

It suits normal, combination, oily and sensitive skin looking for first routine step after cleansing. Fragrance is on the ingredient list, so anyone avoiding added scent should check the list before buying.

How do I use the True Mushroom LX Treatment Toner 120ml?

Sweep across a cleansed face with a cotton pad or press in with palms as the first step after cleansing. Give it a few weeks in that slot before judging the result, since a toner works cumulatively rather than after one use.

Is the True Mushroom LX Treatment Toner 120ml the authentic Korean-market formula?

Yes. We stock The SAEM's Korean-market formula rather than a version reformulated for US shelves. What ships is the 120ml unit sold on Korean shelves, with the Korean barcode and batch code intact on the box.

How it works

True Mushroom LX Treatment Toner 120ml is a Korean color and skincare brand known for approachable, everyday formulas, formulated as a toner for the Korean market rather than a US-shelf reformulation. Niacinamide is one of the most established multi-tasking actives in Korean formulation, valued for supporting an even, calm-looking tone and a smoother surface texture with continued use. It sits at position 16 of 37 ingredients on this row's own list, ahead of most of the formula's supporting agents. Adenosine is a wrinkle-care ingredient standard across Korean cosmetics, commonly included to support a firmer, smoother-looking surface as part of a daily routine. Further down the list, Hydrolyzed Hyaluronic Acid appears at position 32 of 37, adding a supporting layer rather than the lead role.

Key benefits

Niacinamide appears at position 16 of 37 on the ingredient list, ahead of most of the formula's supporting agents.
Adenosine closes out the back half of the list at position 24 of 37, a supporting rather than lead role.
Hydrolyzed Hyaluronic Acid closes out the back half of the list at position 32 of 37, a supporting rather than lead role.
Beta-Glucan closes out the back half of the list at position 30 of 37, a supporting rather than lead role.
Acetyl Hexapeptide-8 closes out the back half of the list at position 36 of 37, a supporting rather than lead role.
Fragrance is listed, so this is a scented rather than fragrance-free formula.

How to use

Sweep across a cleansed face with a cotton pad or press in with palms as the first step after cleansing.

1 of 3

32 of 36 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.
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.
Methyl Gluceth-10 humectant: A sugar-derived humectant, the lighter counterpart of methyl gluceth-20. It holds water and gives a smooth, non-tacky slip.
Tremella Fuciformis Extract (3.51%) plant extract: Tremella Fuciformis is snow mushroom. Its polysaccharide holds even more water than hyaluronic acid for its weight, which is why it appears in hydrating Korean formulas as a plant alternative.
Sparassis Crispa Extract (3.51%) plant extract: Cauliflower mushroom extract, one of the richest natural sources of beta-glucan. It hydrates and leaves a soft film.
Ganoderma Lucidum Extract (3.51%) plant extract: Reishi mushroom extract. Like most mushroom extracts it carries beta-glucan-type polysaccharides, which hold water and leave a light film.
Phellinus Linteus Extract (3.51%) plant extract: Sanghuang, a hard bracket mushroom used in Korean and Chinese herbal tradition. Its extract carries water-holding polysaccharides.
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.
Polyglycerin-3 humectant: Polyglycerin-3 is a short chain of glycerin units used as a gentler, less sticky humectant. It also helps oils and water stay blended.
Saccharomyces Ferment Filtrate (2.48%) ferment: Saccharomyces Ferment Filtrate is a brewers yeast ferment filtered clear. It supplies amino acids, B vitamins and sugars, and it is one of the ferments the Korean essence category was built on.
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.
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.

Glycereth-26 humectant: Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
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.
Psidium Guajava Leaf Extract plant extract: Guava leaf extract. The leaf is high in tannins and quercetin, more so than the fruit, and the extract is used as an astringent antioxidant botanical.
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.
Ammonium Acryloyldimethyltaurate/VP Copolymer thickener: This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
Opuntia Ficus-Indica Stem Extract plant extract: Prickly pear cactus stem extract, from the pad rather than the fruit. The pad is full of mucilage, so the extract hydrates and leaves a cushioned feel.
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.
Dipotassium Glycyrrhizate active: Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
Adenosine active: Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.
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.
Fragrance fragrance: Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
Polyglutamic Acid humectant: Polyglutamic Acid comes from fermented soy and holds several times more water than hyaluronic acid for its weight. It forms a light film on the surface, so it is often layered with hyaluronic rather than replacing it.
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.
Beta-Glucan polysaccharide: Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
Hydrolyzed Glycosaminoglycans humectant: Hydrolyzed Glycosaminoglycans are short fragments of the sugar chains that sit between cells in skin, hyaluronic acid among them. They act as humectants and give a cushioned feel.
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.
Mannitol humectant: Mannitol is a sugar alcohol used as a humectant and antioxidant. It hydrates and helps stabilise the rest of the formula against oxidation.
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.
Acetyl Hexapeptide-8 peptide: Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
Ergothioneine antioxidant: Ergothioneine is a sulphur-bearing amino acid mushrooms make. It is a strong antioxidant and is stable in water.
