The COSRX AHA 2 BHA 2 Blemish Treatment Serum is designed for acne-prone skin, providing a gentle yet effective solution for blemishes, blackheads, and clogged pores caused by excess sebum. Combining the exfoliating properties of AHA and the deep-cleaning benefits of BHA, this serum targets multiple skin concerns including rough texture and pore congestion. Its unique texture, blending oil and pure vitamin C, absorbs smoothly into the skin, promoting a supple and radiant finish. To use, apply a small amount after cleansing, blend thoroughly, and follow with a moisturizer to enhance its benefits. For best results, use consistently and protect the skin with sunscreen during the day.
