Key actives
Centella Asiatica Leaf Extract
Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
Asiaticoside
Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
Madecassic Acid
Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
Asiatic Acid
Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
Niacinamide
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
Oligopeptide-1
Oligopeptide-1 is a short synthetic peptide. Oligo means the chain is short without the name fixing its length, which is why oligopeptides appear in blends where several sequences work together.
Oligopeptide-3
Oligopeptide-3 is another short synthetic peptide sequence. Numbered oligopeptides that sit next to each other on a label are separate sequences, not doses of one ingredient.
How to use
- Apply after the toner while the skin is still damp so a small dose covers the face in one pass.
- Press it in with the flats of the fingers rather than rubbing it around in circles.
- Follow with a light cream to hold it in place, then sunscreen as the final morning step.
- Do not stack it with an exfoliating step in the same sitting, since the reason you bought it is that the skin already reacts.
How do I know this is authentic and not a US-reformulated version?
Check the box against the listing: an authentic Korean-market SKU carries Korean-primary packaging and an intact Korean-market batch code, not a US-only relabel. Numbuzin's Korean-market formulas are sourced specifically to preserve that, rather than substituted for the US-shelf version some retailers carry under the same name.
When in a routine should I use this serum?
Use it as the serum step, AM and PM, after toner and before moisturizer. Placing a serum out of order is the most common reason a Korean routine feels like it is not working, so keep this one at its own step rather than doubling it up with a product built for a different stage. Give it a few weeks at that placement before judging the result.
Is this the same formula sold in Korea, or a US version?
This is sourced for the Korean market rather than reformulated for US shelves. Numbuzin sells a separate reformulation on some US shelves, and this listing is not that version. The Korean-market batch coding and packaging travel with it, which is the detail worth checking against the box on arrival.
What does Centella Asiatica Leaf Extract do in this formula?
Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid. It is named on this product's own ingredient panel.
What does Niacinamide do in this formula?
Niacinamide supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable. It is one of the most studied actives in Korean formulation for tone evenness and is gentle enough for daily AM and PM use. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.

How it works
The panel on this serum names five forms of centella asiatica rather than one: Centella Asiatica Leaf Extract, Asiaticoside, Madecassic Acid, Asiatic Acid, Madecassoside. Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid. On this panel it sits alongside Niacinamide, Oligopeptide-1 and Oligopeptide-3. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
Worth knowing
- Patch test on the inner arm first if trying a new brand's formula for the first time.
- Stop use and check the ingredient list against any known sensitivities before continuing.

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.
