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 The old warning that they cancel out is largely outdated.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 fermented skincare?
Fermented skincare uses ingredients broken down by microorganisms, like galactomyces, rice or yeast ferments, which Korean brands prize for adding glow and a smoother-looking texture. Fermentation is thought to make some ingredients lighter and more skin-friendly, and it's a signature of many Korean essences.
Can I mix Korean and Western skincare?
Yes. Products do not care where they were made — what matters is the ingredients and the order you apply them. Layer thinnest to thickest, avoid stacking two exfoliating actives, and introduce anything new one at a time.
