## How it works

Retinol leads the ingredient panel on this serum. Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises. On this panel it sits alongside Niacinamide, Cholesterol and Phytosteryl/Behenyl/Octyldodecyl Lauroyl Glutamate. 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. Cleanse and tone, then make sure skin is fully dry.
2. Dispense a small amount and press evenly over the face at night, avoiding the eye area.
3. Follow with a moisturizer rather than skipping that final step.
4. Use sunscreen the next morning without exception, not only when skin looks irritated.

## FAQ

### What does the Retinol Boosting 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 Retinol Boosting 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 Retinol Boosting Serum the same formula sold in Korea, or a US version?

This Retinol Boosting 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 Retinol Boosting 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 Retinol Boosting 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.
