Cosrx AHA 2% BHA 2% Blemish Treatment Serum Pure Cotton Balls Pack of 60 - 120g is a breakthrough in targeted blemish care, combining the power of dual exfoliation with hygienic, no-touch application. Formulated with a potent blend of 2% AHA (Alpha Hydroxy Acid) and 2% BHA (Beta Hydroxy Acid), this serum effectively clears clogged pores, removes blackheads and whiteheads, and speeds up the healing of post-acne marks without irritating the skin. Each treatment comes pre-soaked in 100% pure cotton balls, ensuring clean and precise application every time. This mess-free design eliminates the risk of contamination and allows you to directly apply the active ingredients only to affected areas, reducing the chance of over-exfoliation on healthy skin. The cotton balls are conveniently sized, making them perfect for daily spot treatment. The AHA gently exfoliates the skin's surface by removing dead skin cells that contribute to dullness and rough texture, while BHA penetrates deeper to dissolve sebum and debris within the pores. Together, they promote a clearer, smoother complexion and help prevent future breakouts. The irritant-free formula also includes calming agents to soothe redness and sensitivity, making it suitable for acne-prone and sensitive skin. Clinically tested and dermatologist-approved, this blemish serum is free from parabens, sulfates, phthalates, and artificial fragrances. It adheres to Cosrx's clean beauty standards cruelty-free, hypoallergenic, and safe for all skin types. Whether you're dealing with occasional breakouts or persistent acne, this treatment offers fast, effective results without harshness.
