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 The old warning that they cancel out is largely outdated.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 are ceramides in skincare?
Ceramides are lipids that naturally make up part of the skin barrier, helping it hold moisture and stay resilient. In Korean skincare they're used to support and replenish a comfortable, hydrated barrier, especially for dry or sensitive skin, and pair well with centella and panthenol.
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.
Can I use vitamin C and retinol together?
Not in the same layer, but easily in the same routine — vitamin C in the morning, retinol at night. That split suits both: vitamin C partners with sunscreen, and retinoids are degraded by light.
