Key actives
Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. It is the entry this serum is named after, and the list carries it.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named sixth on this serum's list, alongside Gluconolactone.
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. It is named thirty-second on this serum's list, alongside Gluconolactone.
Capryloyl Salicylic Acidexfoliant
Capryloyl Salicylic Acid is salicylic acid with a fatty tail, sometimes sold as LHA. It stays nearer the surface than salicylic acid and works at a higher pH, so it exfoliates more evenly and more gently. It is named thirty-fourth on this serum's list, alongside Gluconolactone.
Salicylic Acidexfoliant
It loosens the dead cells that block pores and is used for the look of congested, oily skin. It is named forty-third on this serum's list, alongside Gluconolactone.
How to use
- Use it as the serum step, AM and PM, after toner and before moisturizer, giving it a moment to settle before the next step.
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 Gluconolactone and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Gluconolactone and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
Does this serum contain fragrance?
Yes. The ingredient list names Limonene and Linalool. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this serum is not the one.
What else is on the list besides Gluconolactone?
Niacinamide, Adenosine and Capryloyl Salicylic Acid. The order they are printed in on this serum's panel is the order on the box, so you can see where Gluconolactone sits relative to them. Further down the same panel: Salicylic Acid, Acetyl Hexapeptide-8 and Acetyl Octapeptide-3.

How it works
The Egg PHA Pore Serum is a 55g serum, used after toner and before moisturizer, morning and evening. The exfoliant it is built around is Gluconolactone, named twenty-sixth on its own ingredient list. The same list carries Niacinamide, Adenosine and Capryloyl Salicylic Acid, 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 serum format rather than by the list alone. This is the Original Korean Formula, the serum A'PIEU sells in Korea, Gluconolactone and all.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Gluconolactone on the list.
- This list names Limonene and Linalool, so skip it if fragrance components are something you avoid.
- Citric Acid and Gluconolactone on this list makes this serum 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.
BHAs like salicylic acid get really deep into the pores, whereas the water-soluble ones don't go as deep.
Samantha Stein, PA-CDermatology physician assistant, Cleveland Clinic 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.

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.
