What is TRE.AC pH Condition Toner?

It is Cell Fusion C's toner (200ml). Its own ingredient list names Sodium Hyaluronate, Lactic Acid, Ceramide NP, Purified Water, positioned the way the key-actives panel on this page describes, rather than actives assumed from the product name. It is used right after cleansing, to rebalance the skin and prep it for the next step.

How do I use TRE.AC pH Condition Toner?

Sweep across a cleansed face and neck with a cotton pad or press in with clean hands, then continue with the rest of the routine without rinsing. Keep the same order every time you use it so you can tell what is actually working, and give a new step a few weeks before judging the result.

Is TRE.AC pH Condition Toner the authentic Korean-market formula?

Yes. This listing is Cell Fusion C's Korean-market formula: the same ingredient list, barcode and batch code as the unit sold on shelves in Korea, rather than a version reformulated for US retail. That is the whole reason to buy a Korean-market brand from a specialist rather than a general retailer.

Who is TRE.AC pH Condition Toner suited for?

It is not restricted to any one skin tone or age group. As with any new step, patch-test on the inner arm first if you are new to this formula or to Cell Fusion C.

Key actives

1Purified Water

Named directly on this formula's own ingredient list, at position 1 of 35 on this label's own ingredient list. This is read from the manufacturer's own listed order rather than assumed from the product name, which is what separates a genuine formula component from a name-only claim.

11Sodium Hyaluronate

the salt form of hyaluronic acid, a humectant that holds water at the skin's surface. It sits at position 12 of 35 on this label's own ingredient list. This is read from the manufacturer's own listed order rather than assumed from the product name, which is what separates a genuine formula component from a name-only claim.

All products with Sodium Hyaluronate

18Lactic Acid

a gentler AHA exfoliant that also carries some humectant benefit. It sits at position 19 of 35 on this label's own ingredient list. This is read from the manufacturer's own listed order rather than assumed from the product name, which is what separates a genuine formula component from a name-only claim.

All products with Lactic Acid

19Ceramide NP

a barrier lipid included to support the skin's own barrier structure. It sits at position 20 of 35 on this label's own ingredient list. This is read from the manufacturer's own listed order rather than assumed from the product name, which is what separates a genuine formula component from a name-only claim.

1 of 4

28 of 34 explained

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.
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.
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.
Pectin polysaccharide: Pectin is the gelling sugar in fruit peel, and in a hydrocolloid patch it is the half that takes up fluid. It swells as it absorbs, which is what turns a patch white.
White Willow Bark Extract plant extract: Willow Bark Extract carries salicin, the plant compound salicylic acid is related to. The two are not interchangeable: willow bark is a mild clarifying extract, not a BHA exfoliant at the levels used in cosmetics.
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.
Hibiscus Sabdariffa Flower Extract plant extract: Roselle hibiscus extract, deep red from anthocyanins and naturally acidic. It carries plant acids and is used as an antioxidant extract.
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.
Mentha Piperita (Peppermint) Oil fragrance: Peppermint essential oil. Its menthol content is what produces the cool feeling, and it is a commonly declared fragrance material.
Juniperus Mexicana Oil fragrance: Texas cedarwood oil, used for a dry woody note. It is an aromatic ingredient rather than a functional one.
Sodium Lactate humectant: Sodium Lactate is the salt of lactic acid and one of the components of skin's own natural moisturising factor. At the levels used here it is a humectant and buffer rather than an exfoliant.

16 more explained

Lactic Acid exfoliant: Lactic Acid is a larger AHA than glycolic, so it works nearer the surface and is easier on skin, and it is a humectant as well as an exfoliant. It is the AHA of choice for dry skin.
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.
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.
Sucrose Stearate emulsifier: Sucrose Stearate is a sugar-based emulsifier chosen for a light finish in formulas built for reactive skin.
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.
Palmitic Acid fatty acid: Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
Hydrolyzed Lupine Protein protein: Hydrolyzed Lupine Protein comes from the lupin bean, which is unusually protein rich. Hydrolysed, it dissolves and works as a conditioning, water-holding protein.
Saccharide Isomerate humectant: A plant-sugar complex whose structure resembles the sugars already bound to the skin surface, so it stays through washing. It is used as a long-acting humectant.
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.
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.
PEG-40 Hydrogenated Castor Oil emulsifier: PEG-40 Hydrogenated Castor Oil is the most used solubiliser in clear toners and micellar waters. It holds small amounts of oil and fragrance in solution without turning the formula cloudy.
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.
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.

How it works

TRE.AC pH Condition Toner is a toner from Cell Fusion C. Cell Fusion C is a Korean dermo-cosmetic brand developed with a background in post-procedure and sensitive-skin care, with named ranges built around cooling, pH-balancing and brightening. On this jar's own ingredient list, Sodium Hyaluronate, Lactic Acid, Ceramide NP, Purified Water are named directly, which is what the key-actives panel on this page is built from rather than from the product name alone. Sodium Hyaluronate is the salt form of hyaluronic acid, a humectant that holds water at the skin's surface, and it is why this toner is positioned the way it is. Use it right after cleansing, to rebalance the skin and prep it for the next step; a toner's job is to rebalance the skin's surface so what follows absorbs evenly. Cell Fusion C sells this as the Korean-market formula, the same one stocked on shelves in Korea rather than a version built for the US market.

How to use

Sweep across a cleansed face and neck with a cotton pad or press in with clean hands, then continue with the rest of the routine without rinsing.

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.

Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.
