Frequently Asked Questions
COSRX BHA Blackhead Power Liquid contains salicylic acid, a beta hydroxy acid that dissolves oil and dead skin cells inside pores. Unlike surface exfoliants, BHA penetrates deep into pores where blackheads form, helping to unclog them and prevent future buildup. This makes it particularly effective for oily and congestion-prone skin.
COSRX BHA is formulated to be gentle, with a 4% salicylic acid concentration balanced with skin-soothing ingredients. However, it may cause initial dryness or sensitivity in very reactive skin types. Start with 2-3 times per week and gradually increase frequency as your skin builds tolerance. If you have active inflammation or compromised skin barrier, consult a dermatologist first.
For most skin types, 3-4 times per week is ideal to allow skin to adjust. Those with resilient, oily skin may tolerate daily use, but starting with less frequent application helps minimize irritation and dryness. Listen to your skin—if you experience excessive dryness or redness, reduce frequency and ensure you're using a good moisturizer.
