Where does this lotion go in my routine?

As the last skincare step, morning and evening, over serum. Anything thinner than a lotion 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 Gluconolactone and not three changes at once.

What else is on the list besides Gluconolactone?

Tocopherol, Sodium Ascorbyl Phosphate and Ceramide NP. The order they are printed in on this lotion's panel is the order on the box, so you can see where Gluconolactone sits relative to them. Further down the same panel: Cholesterol, 7-Dehydrocholesterol and Pollen Extract.

How it works

The Dermoisture Barrier.D Daily Lotion is a 300ml lotion, used as the last skincare step, morning and evening, over serum. The exfoliant it is built around is Gluconolactone, named twenty-seventh on its own ingredient list. The same list carries Tocopherol, Sodium Ascorbyl Phosphate and Ceramide NP, so the exfoliant is not the only thing on it worth naming. How much of the Gluconolactone stays on the skin, and for how long, is decided by the lotion format rather than by the list alone. Dr.G sells this Gluconolactone lotion in Korea, and this is that version.

Key actives

12Ceramide NPbarrier 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. It is named twelfth on this lotion's list, alongside Gluconolactone.

All products with Ceramide NP

23Tocopherolantioxidant

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. It is named twenty-third on this lotion's list, alongside Gluconolactone.

All products with Tocopherol

26Cholesterolbarrier 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. The panel names it twenty-sixth on this lotion's list, beside Gluconolactone.

All products with Cholesterol

27Gluconolactoneexfoliant

Gluconolactone is a PHA, the gentlest exfoliant class. On this lotion's own ingredient list it is named twenty-seventh.

All products with Gluconolactone

47Sodium Ascorbyl Phosphateantioxidant

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. It is named forty-seventh on this lotion's list, alongside Gluconolactone.

45 of 50 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.
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.
Hydrogenated Polydecene emollient: Hydrogenated Polydecene is a synthetic hydrocarbon emollient used in place of mineral oil. It is stable, has no scent, and gives a cushioned slip without oxidising.
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.
Polyglyceryl-3 Distearate emulsifier: Polyglyceryl-3 Distearate is a plant-derived emulsifier used to hold oil and water together in creams and lotions.
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.
Vinyl Dimethicone silicone: Vinyl Dimethicone is a silicone used as a building block of the crosspolymer gels that give a formula its soft, blurring feel.
Silica absorbent: Silica is finely milled mineral, essentially very pure sand. It absorbs oil, stops powders clumping and soft-focuses the look of pores and fine lines.
Sorbitan Stearate emulsifier: Sorbitan Stearate is a mild emulsifier and thickener used to hold oil and water together in creams.
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.
Cetearyl Olivate emulsifier: Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's own.
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.

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.
Sorbitan Olivate emulsifier: Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
Olea Europaea (Olive) Oil Unsaponifiables emollient: The fraction of olive oil that cannot be turned into soap, where its sterols and squalene concentrate. It softens skin and helps hold water in.
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 Citrate emulsifier: Glyceryl Stearate Citrate is a mild, citrate-modified emulsifier. It holds oil and water together and is chosen for formulas aimed at reactive skin.
Polyacrylate Crosspolymer-6 thickener: Polyacrylate Crosspolymer-6 is a thickener chosen for a notably fresh, bouncy gel feel that breaks down to water on the skin.
Glyceryl Glucoside humectant: Glyceryl Glucoside is glycerin bound to glucose, from the resurrection plant. It is a humectant that holds water in the outer layer of skin.
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.
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.
Sucrose Cocoate emulsifier: Sucrose Cocoate is table sugar joined to coconut fatty acids. It is a very mild emulsifier and cleanser that also holds water, so it turns up in gentle cleansers and toners.
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.
Gluconolactone exfoliant: Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
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.
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.
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.
Pollen Extract plant extract: Extract of flower pollen collected by bees. Pollen carries amino acids, sugars, vitamins and flavonoids, and the extract is used as a conditioning ingredient.
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.
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.
Xylitylglucoside humectant: Xylitylglucoside is a sugar-derived humectant, the third member of the xylitol blend. Together the three hold water in the outer layer for longer than any of them does alone.
Anhydroxylitol humectant: Anhydroxylitol is a xylitol derivative used as a humectant. It is almost always part of the xylitol, anhydroxylitol and xylitylglucoside blend sold as a moisture-retention complex.
T-Butyl Alcohol solvent: t-Butyl Alcohol is the bittering agent added to cosmetic ethanol so it cannot be drunk. It appears in tiny amounts alongside alcohol denat. and does no formulation work of its own.
Polyglyceryl-10 Stearate emulsifier: Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
Polyglyceryl-10 Oleate emulsifier: Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
Xylitol humectant: Xylitol is a sugar alcohol humectant. It holds water in the outer layer of skin and is often paired with anhydroxylitol and xylitylglucoside as a hydration trio.
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.
Aluminum/Magnesium Hydroxide Stearate dispersant: A mineral soap used to suspend powders and thicken an oil phase, which is what stops pigment settling to the bottom of a bottle.
Myristic Acid fatty acid: Myristic Acid is a saturated fatty acid used to thicken and, with a base added, to build the foam in a soap-style cleanser.
Tremella Fuciformis Polysaccharide 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.
Sodium Stearoyl Glutamate emulsifier: Sodium Stearoyl Glutamate is an amino-acid-derived emulsifier. It holds oil and water together and is mild enough for formulas built for reactive skin.
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.
7-Dehydrocholesterol barrier lipid: 7-Dehydrocholesterol is the sterol skin holds as the precursor to vitamin D. In a formula it behaves as a barrier lipid, closely related to cholesterol.
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.
Calcium Chloride mineral: Calcium Chloride is a mineral salt used in traces to balance a formula and to firm up gels made with alginate or gellan gum.

This means that gluconolactone acts as an exfoliating acid, but also as a moisturizer. It has moisturizing, soothing, and lightening properties, working well on dry skin.
