How it works

Bio Intense Glutathione White Silky Toner is MEDIPEEL's toner, formulated to resurface the skin with a thin, fast-absorbing layer right after cleansing, prepping it for the richer steps that follow. Niacinamide sits right at the top of the ingredient list, just after the base, a barrier-supporting, tone-evening amide that also supports a brighter-looking tone with regular use. Glutathione sits high on the ingredient list, an antioxidant tripeptide central to this line's brightening, even-tone positioning. Dipotassium Glycyrrhizate sits high on the ingredient list, a licorice-root derivative valued for its calming, skin-conditioning role. MEDIPEEL's Bio-Intense Glutathione White line is the brand's brightening range, built around glutathione paired with niacinamide.

1 of 3

63 of 64 explained

Hippophae Rhamnoides Water plant extract: Hippophae Rhamnoides is sea buckthorn. Its water is used in place of plain water as a base and carries traces of the fruit's vitamins.
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.
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.
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.
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.
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.
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.
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.
PPG-13-Decyltetradeceth-24 emulsifier: PPG-13-Decyltetradeceth-24 is a solubiliser used to hold oils and fragrance in a clear water-based formula.
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.
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.
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.

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.
Glutathione antioxidant: Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
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.
Cetearyl Alcohol fatty alcohol: Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
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.
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.
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.
Terminalia Ferdinandiana Fruit Extract plant extract: Kakadu plum fruit extract, the highest natural source of vitamin C known. It is used as a plant antioxidant.
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.
Lecithin emulsifier: Lecithin is a soy or sunflower-derived phospholipid, the same class of molecule cell membranes are built from. It emulsifies oil into water and is the basis of the liposomes formulators use to carry actives.
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.
Acetyl Glutamine amino acid: Glutamine with an acetyl group added, which makes it more stable in water. It is used as a conditioning amino acid.
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.
Folic Acid vitamin: Folic Acid is vitamin B9. It is used in a formula as a conditioning vitamin, usually as part of a B-complex blend.
Bacillus/Soybean Ferment Extract ferment: This is soybean fermented by Bacillus, the process behind Korean cheonggukjang. Fermentation cuts the soy proteins into smaller pieces and produces polyglutamic acid, a strong humectant.
Oligopeptide-1 peptide: Oligopeptide-1 is a short synthetic peptide. Oligo means the chain is short without the name fixing its length, which is why oligopeptides appear in blends where several sequences work together.
Hexapeptide-11 peptide: Hexapeptide-11 is a yeast-derived six-amino-acid peptide used for the look of resilience and firmness.
Oligopeptide-2 peptide: Oligopeptide-2 is a short synthetic peptide, water soluble like most of the unmodified oligopeptides. It is supplied as one component of a blend.
Oligopeptide-3 peptide: Oligopeptide-3 is another short synthetic peptide sequence. Numbered oligopeptides that sit next to each other on a label are separate sequences, not doses of one ingredient.
Hydrolyzed Pea Protein protein: Pea protein cut into small fragments so it dissolves in water. It is a plant protein used as a humectant and a light film former.
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.
Phytosterols emollient: Phytosterols are plant sterols, structurally close to the cholesterol in skin's own lipid layer. They soften skin and help the oil phase of a formula hold together.
Squalane emollient: Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
Olea Europaea (Olive) Fruit Oil emollient: Olive Fruit Oil is high in oleic acid and plant sterols. It is a rich emollient that suits dry skin and is heavy enough that blemish-prone skin often does not get on with it.
Tocopherol antioxidant: Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
Polyglyceryl-10 Stearate emulsifier: Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
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.
Hyaluronic Acid humectant: Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
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.
Hydroxypropyltrimonium Hyaluronate humectant: Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
Potassium Hyaluronate humectant: Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of 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.
Sodium Ascorbyl Phosphate antioxidant: Sodium Ascorbyl Phosphate is a water-soluble, stable vitamin C salt. It works at near-neutral pH, so it appears in formulas aimed at skin that pure ascorbic acid leaves stinging.
Butyrospermum Parkii (Shea) Butter emollient: Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
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.
Sodium Hyaluronate Crosspolymer humectant: Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
Biotin vitamin: Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
Pyridoxine vitamin: Pyridoxine is vitamin B6. In a formula it is a conditioning vitamin, most often in B-complex blends and scalp products.
Cyanocobalamin vitamin: Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin.
Riboflavin vitamin: Riboflavin is vitamin B2, and it is a strong yellow, so a formula carrying it often has a colour nobody added on purpose.
Thiamine HCl vitamin: Thiamine is vitamin B1, supplied as its hydrochloride salt so it dissolves in water. It is a conditioning vitamin and usually appears as part of a B-complex.
Retinol active: Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises.
Bioflavonoids antioxidant: Bioflavonoids is a collective declaration for the flavonoid fraction of a plant extract, usually citrus. It names a class of plant antioxidants rather than one compound.
Sodium Acetylated Hyaluronate humectant: Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
Menadione vitamin: Menadione is a synthetic form of vitamin K. In a formula it is used at very low levels as a conditioning vitamin.
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.
Copper Tripeptide-1 peptide: Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
Palmitoyl Pentapeptide-4 peptide: Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
Linoleic Acid fatty acid: Linoleic Acid is an essential omega-6 fatty acid and the main fatty acid in sunflower, safflower and rosehip oil. In a formula it is a lipid that softens and sits in the outer layer.
Beta-Carotene antioxidant: Beta-Carotene is an orange plant pigment and a vitamin A precursor. It is used as an antioxidant and it tints a formula, which is often why it is there.
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.
