What order do you apply Korean skincare?
A general Korean order goes thinnest to thickest: cleanse, then toner, essence, serum or ampoule, eye cream, moisturizer, and sunscreen last in the morning. Lighter, watery layers go on first so they absorb, with richer creams and sun protection sealing everything in.
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 The old warning that they cancel out is largely outdated.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.
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.
