The COSRX AHA 7 Whitehead Power Liquid is a leave-on exfoliating essence built around 7% glycolic acid (AHA). It works on the surface of the skin to loosen and sweep away dead skin cells, leaving a smoother feel and a fresher, more even-looking complexion.
Glycolic acid is one of the smallest AHA molecules, so it spreads easily across the skin and helps refine the look of rough, uneven texture and dull-looking areas. To keep the formula comfortable, COSRX pairs it with hyaluronic acid for added hydration and apple fruit water, so the essence supports skin that looks soft and balanced rather than tight.

Who is it for?
This essence is best suited to dry and combination skin. Because it contains an exfoliating acid, it is recommended for people who already have some experience using AHA products in their routine.
How to use it
Use in the evening after cleansing and toning. Apply a thin layer to dry skin, avoiding the eye and lip area, and follow with your usual moisturiser. Start two to three times a week and adjust as your skin gets used to it. Because AHAs can make skin more sensitive to sunlight, always apply sunscreen during the day.
