## How it works

Medicube TXA Niacinamide 15% Serum 30ml is a serum built for the treatment step right after toner. Its ingredient list leads with Niacinamide, Tranexamic Acid, and Arbutin, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Niacinamide does the most work here as a tone and texture, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the treatment step right after toner, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the TXA Niacinamide 15% Serum 30ml line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

## How to use

1. Start every other day and move to daily only once the skin stays comfortable.
2. Apply after toner on barely damp skin, pressing three or four drops across the face.
3. Follow with a moisturiser, then sunscreen if it is a morning routine.
4. Do not layer it with an exfoliating acid in the same routine, since two sharp products at once is what causes stinging.

## FAQ

### What does the TXA Niacinamide 15% Serum 30ml actually contain?

Its ingredient list is led by Niacinamide, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.

### How do I use the TXA Niacinamide 15% Serum 30ml?

Use this serum as the treatment step right after toner. To apply, smooth or press onto cleansed, toned skin and follow with moisturizer. Keep it to AM/PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.

### Is the TXA Niacinamide 15% Serum 30ml the same formula sold in Korea, or a US version?

This TXA Niacinamide 15% Serum 30ml is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.

### Can I use the TXA Niacinamide 15% Serum 30ml with other actives in my routine?

Yes, as long as it is used in its own step, the treatment step right after toner, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.

### Who is the TXA Niacinamide 15% Serum 30ml suited for?

It suits most skin types looking for treatment step right after toner rather than a single acute problem. It comes in a 30ml format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.
