The Cosrx BHA Blackhead Power Liquid 100ml is a gentle yet effective exfoliating treatment designed to target blackheads, whiteheads, and clogged pores. Formulated with 4% betaine salicylate (a milder derivative of salicylic acid), it penetrates deep into pores to dissolve impurities and excess sebum without irritation. This lightweight liquid also contains willow bark water and niacinamide to soothe inflammation and brighten skin tone. Ideal for oily, acne-prone, or combination skin types, it helps refine texture and prevent future breakouts with regular use. The non-drying formula works as both a chemical exfoliant and pore-refining toner, making it a versatile addition to any skincare routine. Users should incorporate it 2-3 times weekly to maintain clear, smooth skin with minimized pores. Its cruelty-free and hypoallergenic formulation ensures suitability for sensitive skin seeking a gentle BHA solution.
