Key actives
Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. On this lotion's own ingredient list it is named twenty-seventh.
Tocopherolantioxidant
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.
Sodium 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.
Ceramide 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.
Cholesterolbarrier 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.
How to use
- Use it as the last step of a routine (or before a separate night cream at night), sealing in the layers underneath. AM and PM.
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.
Worth knowing
- Patch test this lotion on a small area and wait a day before using it more widely, especially with Gluconolactone on the list.
- Gluconolactone on this list makes this lotion an exfoliating step, so do not stack it with another one on the same night.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
People with dry, flaky skin are more likely to see a benefit from using vitamin E because it enhances moisturization.
Amy Kassouf, MDDermatologist, Cleveland Clinic Using topical vitamin C can result in less cell damage and better-looking skin.

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.
