How it works
The Boosting Shot Gel is a 250ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named third on its own ingredient list. The same list carries Dipotassium Glycyrrhizate, Adenosine and Allantoin, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the serum format rather than by the list alone. Centellian24 sells this Niacinamide serum in Korea, and this is that version.

Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this serum's own ingredient list it is named third.
Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named fifteenth on this serum's list, alongside Niacinamide.
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 eighteenth on this serum's list, beside Niacinamide.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it twenty-eighth on this serum's list, beside Niacinamide.
Copper Tripeptide-1peptide
Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines. It is named forty-ninth on this serum's list, alongside Niacinamide.

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 Niacinamide and not three changes at once.
Does this serum contain fragrance?
Yes. The ingredient list names Fragrance. It sits 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 Niacinamide?
Dipotassium Glycyrrhizate, Adenosine and Allantoin. The order they are printed in on this serum's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Copper Tripeptide-1, Acetyl Hexapeptide-8 and Tocopherol.

How to use
- Use it after cleansing and before your serum, morning and evening.
- A generous layer pressed over damp skin, and at this size use it on the neck and chest too.
- In hot weather it can be the only thing after cleansing, with sunscreen over it in the morning.
- Twice a day, and layer while the skin is still damp rather than after it has dried.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- This list names Fragrance, so skip it if fragrance components are something you avoid.

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.
