Nine less B-Boost 10% Niacinamide Serum

The Nine Less B-Boost 10% Niacinamide Serum 30ml is a K-beauty serum with 10% niacinamide, as the name says. Niacinamide is a well-known ingredient for helping skin look balanced and even, and it's especially popular with people who have oily or combination skin.

How to use: after toner, apply a few drops to the face and pat gently until absorbed. Follow with moisturiser. Use morning and/or night.

If you're new to niacinamide, start once a day and patch test first. Always use sunscreen during the day.

It pairs well with the Nine Less A-Control azelaic acid serum if you alternate them.
