How it works
Pantothenic Acid is named on the ingredient panel on this formula. Pantothenic Acid is vitamin B5, the form skin converts panthenol into. It is used as a conditioning humectant that leaves skin feeling soft rather than tight. On this panel it sits alongside Zinc PCA and Niacinamide. Zinc PCA pairs zinc with the humectant PCA. It is used in oily and blemish-prone formulas for the look of shine and visible pores, and it hydrates at the same time.

Key actives
Pantothenic Acid
Pantothenic Acid is vitamin B5, the form skin converts panthenol into. It is used as a conditioning humectant that leaves skin feeling soft rather than tight.
Zinc PCA
Zinc PCA pairs zinc with the humectant PCA. It is used in oily and blemish-prone formulas for the look of shine and visible pores, and it hydrates at the same time.
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.
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 skincare formula?
Use it as the routine step, AM and PM, worked into the wider routine. Placing a skincare formula 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 the exact Korean-market formula, not a US-shelf reformulation. 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 Zinc PCA do in this formula?
Zinc PCA is a zinc salt Korean formulas add to oily-skin lines to help balance the look of surface shine. It is a common supporting ingredient in Korean formulas aimed at combination and oily skin, usually paired with a lighter overall texture. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.
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.
