AHA / BHA / PHA

AHA (Alpha Hydroxy Acid), BHA (Beta Hydroxy Acid) and PHA (Polyhydroxy Acid) are types of chemical exfoliants. AHA works on the skin's surface and is ideal for dry or dull skin. BHA penetrates deeper into the pores, making it perfect for oily or acne-prone skin. PHA is the gentlest option, suitable for sensitive skin. All three help remove dead skin cells and reveal a smoother, brighter complexion. Discover our full collection of exfoliants.

Exfoliating with AHA, BHA or PHA helps to gently remove dead skin cells that can clog pores, cause uneven texture, or dullness. It encourages cell renewal, smoothes the skin, and enhances the absorption of other skincare products. Try the COSRX BHA Blackhead Power Liquid or the Pyunkang Yul Peeling Gel for gentle yet effective exfoliation.

If you have dry or dull skin, go for AHA (like glycolic or lactic acid). Oily or acne-prone skin benefits more from BHA (such as salicylic acid). If your skin is sensitive, PHA is your best friend due to its mild nature. For combination skin, try multi-acid products like the Anua Peach 70% Niacinamide Serum, which balances and gently exfoliates.

Use your exfoliant after cleansing but before applying serum or moisturizer. Start with 1–2 times a week and build up as your skin gets used to it. We recommend using acids in the evening, and always following with SPF the next morning. Browse our Korean sunscreens for the perfect sun protection. Want to learn more about layering?
