Can you use vitamin C and niacinamide together?
Yes, current understanding is that vitamin C and niacinamide can be used together safely, and many Korean formulas combine them. The old warning that they cancel out is largely outdated. If your skin is sensitive, you can still apply them at different times of day to be cautious.
What does niacinamide do?
Niacinamide is a form of vitamin B3 widely used in Korean skincare to help brighten the look of dullness, refine the appearance of pores and support the skin barrier. It's gentle, well tolerated by most skin types and pairs easily with many other ingredients.
What is hyaluronic acid and how do you use it?
Hyaluronic acid is a humectant that draws water into the skin for a plumper, hydrated look. In Korean routines it's best applied to damp skin and sealed with a moisturizer on top, so the moisture it attracts stays locked in rather than evaporating.
