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.
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 BHA and what does it do?
BHA, usually salicylic acid, is an oil-soluble exfoliant that can penetrate pores to dissolve oil and dead skin, helping refine the look of texture and blemish-prone skin. In Korean routines it's used a few times weekly, with sunscreen by day, to avoid over-exfoliating.
What is the difference between AHA and BHA?
AHAs like glycolic and lactic acid are water-soluble and work on the skin's surface to brighten and smooth, while BHA like salicylic acid is oil-soluble and gets into pores. In Korean skincare both are used sparingly, a few times weekly, always with daily sun protection.
