Niacinamide is fifth, while hydroxypinacolone retinoate and retinol sit forty-fifth and forty-sixth of fifty-five: the gel matrix of carob gum, cellulose gum and carrageenan does more here than the retinoid.

How it works
The Retinol Serum In Gel Mask is a serum, used after toner and before moisturizer, morning and evening. The active it is built around is Retinol, named forty-sixth on its own ingredient list. The same list carries Niacinamide, Adenosine and Hydroxypinacolone Retinoate, so the active is not the only thing on it worth naming. How much of the Retinol stays on the skin, and for how long, is decided by the serum format rather than by the list alone. IOPE sells this Retinol serum in Korea, and this is that version.
Key benefits
- Retinol, the active this serum is built around
- Niacinamide, Adenosine, Hydroxypinacolone Retinoate and Sodium DNA on the same list, actives
- BHT and Tocopherol further down the same list
- Collagen Extract and Chondrus Crispus Extract further down the same list
- Retinol named forty-sixth on the manufacturer list printed on this page
Key actives
Retinolactive
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. The name on the box points at it, and it is named forty-sixth on this serum's own ingredient list.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. The panel names it fifth on this serum's list, beside Retinol.
Adenosineactive
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. The panel names it twenty-fifth on this serum's list, beside Retinol.
Hydroxypinacolone Retinoateactive
Hydroxypinacolone Retinoate is a retinoid ester that binds skin's retinoid receptors directly, with no conversion step. Brands use it where they want retinoid-style results with less of the flaking retinol brings. It is named forty-fifth on this serum's list, alongside Retinol.
Sodium DNAactive
Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to. It is named fifty-first on this serum's list, alongside Retinol.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum 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 Retinol and not three changes at once.
What else is on the list besides Retinol?
Niacinamide, Adenosine and Hydroxypinacolone Retinoate. The order they are printed in on this serum's panel is the order on the box, so you can see where Retinol sits relative to them. Further down the same panel: Sodium DNA, BHT and Tocopherol.

How to use
- Apply an even layer or unfold the sheet over cleansed skin, leave on for the stated time, then remove or rinse and continue with the rest of the routine.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Retinol on the list.
- Hydroxypinacolone Retinoate is on this list, so keep this serum to the evening and build the nights up slowly rather than starting nightly.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Vitamin A has a molecular structure that's tiny enough to get into the lower layers of your skin, where it finds and boosts collagen and elastin, which is a protein that strengthens your skin's flexibility.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
