Where does this ampoule go in my routine?

After toner and before moisturizer, morning and evening. Anything thinner than an ampoule 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 Glutathione and not three changes at once.

Is this the Korean-market ampoule or a US version?

The Korean-market one, Glutathione and all. We match this ampoule 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 Glutathione?

Niacinamide, Allantoin and Adenosine. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Glutathione sits relative to them. Further down the same panel: Madecassic Acid, Asiaticoside and Asiatic Acid.

How it works

The Glutathione Niacinamide Ampoule Serum is a 40ml ampoule, used after toner and before moisturizer, morning and evening. The antioxidant it is built around is Glutathione, named eleventh on its own ingredient list. The same list carries Niacinamide, Allantoin and Adenosine, so the antioxidant is not the only thing on it worth naming. How much of the Glutathione stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. This is the Original Korean Formula, the ampoule APLB sells in Korea, Glutathione and all.

1 of 5

45 of 46 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.
Centella Asiatica Extract (29.2%) 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.
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.
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 (20,000ppm) 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.
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.
Diethoxyethyl Succinate solvent: Diethoxyethyl Succinate is a solvent that helps water-resistant actives spread and sink in evenly. It also leaves a light, silky feel.
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.
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.
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.
Glutathione (1,000ppm) 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.
Sodium Polyacryloyldimethyl Taurate thickener: Sodium Polyacryloyldimethyl Taurate is a polymer thickener that holds a gel stable even with a lot of salt or acid in the formula.

33 more explained

Glyceryl Acrylate/Acrylic Acid Copolymer film former: This is a polymer that forms a moisture-holding film on the surface, usually supplied with glycerin and propylene glycol as a hydrating complex.
Nelumbo Nucifera Extract plant extract: Lotus extract with the plant part unstated. Lotus carries flavonoids and alkaloids, and its extracts are used as conditioning antioxidant botanicals.
Artemisia Annua Extract plant extract: Artemisia Annua is sweet wormwood, a mugwort relative. Its extract is used in Korean formulas for the look of reactive 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.
Saccharomyces Ferment ferment: Saccharomyces Ferment is a brewer's yeast ferment. It supplies amino acids, sugars and B vitamins and is used as a conditioning, hydrating ferment.
Solanum Melongena (Eggplant) Fruit Extract plant extract: Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.
Melaleuca Alternifolia (Tea Tree) Leaf Extract plant extract: Tea Tree Leaf Extract is the water-based extract rather than the essential oil, so it is far milder and much less aromatic. It is used in formulas for blemish-prone skin.
Hydrolyzed Collagen protein: Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
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.
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.
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.
Hippophae Rhamnoides Fruit Extract plant extract: Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant 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.
Madecassic Acid active: Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
Asiaticoside active: Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
Asiatic Acid active: Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
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.
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.
Glyceryl Stearate emulsifier: Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
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.
Cellulose Gum thickener: Cellulose Gum is plant cellulose modified to dissolve in water. It thickens, holds particles in suspension and gives a smooth, slippery body.
Xanthan Gum thickener: Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
Inulin polysaccharide: Inulin is a plant fructan, most often from chicory root. It holds water and, in a formula, feeds the beneficial bacteria on the surface.
Cellulose absorbent: Cellulose is plant fibre. In a formula it thickens, absorbs oil and, in a sheet mask, is often the fabric itself.
Glucose humectant: Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
Fructose humectant: Fructose is a simple sugar used as a light humectant. It holds water in the outer layer and often arrives as part of a fruit or honey extract.
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.
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.
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.
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.
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.
Sodium Citrate pH adjuster: Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.

Worth knowing

Patch test this ampoule on a small area and wait a day before using it more widely, especially with Glutathione on the list.
Introduce this ampoule on its own for the first week, so anything your skin does is traceable to the Glutathione rather than to three changes at once.
