The Cosrx The Niacinamide 15 Serum – 20ml is a concentrated niacinamide serum from COSRX's "The" line of focused serums. Niacinamide is a popular ingredient for helping skin look more even and balanced, and many people with oily skin like it as part of their routine.
The small 20ml bottle is perfect for a targeted treatment step.
How to use:
- Apply a few drops to clean, toned skin.
- Spread over the face, avoiding the eye area.
- Follow with moisturiser.
- Use sunscreen during the day.
Because the concentration is high, start once a day and patch test first. If you use vitamin C as well, you can apply them at different times of day.
