## How it works

Zinc PCA is named on the ingredient panel on this serum. 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. On this panel it sits alongside Niacinamide, Dipotassium Glycyrrhizate and Salicylic Acid. 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 to use

1. Use the Red Serum after toner and before moisturizer, in the evening.
2. Three or four drops covers the whole face. Press it in with flat palms instead of rubbing it around.
3. Toner first so the surface is damp, then this, then about a minute before your moisturizer goes over the top. Salicylic acid is the entry that puts this step in the evening rather than the morning.
4. Start at two or three evenings a week and build up from there, because salicylic acid is on this list. Do not use it in the same routine as another resurfacing acid or a retinoid.

## FAQ

### What does the Red Serum 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 Red Serum?

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 Red Serum the same formula sold in Korea, or a US version?

This Red Serum 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 Red Serum 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 Red Serum 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.
