How it works
This is a leave-on exfoliating serum rather than a rinse-off scrub, so the work happens over hours instead of in the two minutes you spend at the sink. That longer contact is why the frequency has to be rationed to a few nights a week rather than used daily like a hydrating serum. Eighty millilitres is a generous bottle for this category, which points at whole face use with a second pass on the congested zone rather than dabbing. That is the difference from a peeling gel, which is gentler and gone in minutes but does less for a nose that never quite clears. What you can judge is whether the nose and chin feel smoother under the fingertips after a fortnight.
Key benefits
- Propanediol sits near the top on this product's own ingredient list, a multifunctional glycol that carries moisture and helps preserve the formula.
- A lightweight, non-comedogenic emollient that mimics skin's own lipids, and Squalane is right there in this product's ingredient list, in the first half.
- On this formula's own list, Sodium Hyaluronate shows up in the first half. It is a low-weight hyaluronate that draws water into the surface layers.
Key actives
Squalane
A light emollient high on this list, and the part that keeps a leave-on exfoliating serum from leaving the face feeling stripped.
Sodium Hyaluronate
A humectant that holds water at the surface, which matters more than usual on the nights you have just exfoliated.
Hydrolyzed Hyaluronic Acid
A smaller grade of the same humectant family on this list, chosen for thin formulas where a heavier one leaves a tacky finish.
Glycyrrhiza
A licorice root extract on this list, a common calming partner to exfoliating actives in Korean formulas for oilier skin.
Jojoba
A light plant oil on this list, present in a small share, the sort used to soften how an exfoliating formula feels going on.
What does this serum do?
It is a leave-on exfoliating serum aimed at the congested zone, so it loosens the rough surface layer over hours rather than in the two minutes a scrub gets. Use it a few nights a week. You judge it on whether the nose and chin feel smoother under the fingertips after a fortnight.
Where does it go in my routine?
After cleansing, before your moisturizer, on the nights you use it. A thin layer over the face, a second pass on the nose and chin, then seal with a cream. Keep the rest of that evening simple rather than stacking another strong product on top.
How often is too often?
Nightly is too often for most faces with a leave-on exfoliant. Start at two nights, move to three if the skin stays comfortable, and stop for a week if it starts looking shiny and tight, since that is what over exfoliating looks like well before it looks red.
Do I need sunscreen with it?
Yes, every morning while you are using it, because freshly exfoliated surface skin is more sensitive to light. That is true of any exfoliating routine. If daily sunscreen is not something you are going to do, this is not the right step to add to your routine yet.
Is this the Korean-market formula?
Yes. This is the Original Korean Formula 80ml bottle, the same one sold on Korean shelves.

How to use
- Start at two nights a week and build up only if the skin stays comfortable afterwards.
- Apply a thin layer over the face on clean skin, then a second pass on the nose and chin.
- Follow with a moisturizer the same night, since a leave-on exfoliating step always wants sealing.
- Do not use it on the same night as another exfoliating product, and never on skin that is already stinging.
Worth knowing
- Build up from two nights a week, since a leave-on exfoliant works for hours rather than minutes.
- Wear sunscreen every morning while you are using it, because fresher surface skin is more light sensitive.
- Stop for a week if the face looks shiny and tight rather than smooth, which is what over exfoliating looks like.
