The COSRX BHA Blackhead Power Liquid is able to easily get rid of your blackhead buildups after daily exposure from harsh elements. The liquid essence contains specially formulated BHA molecules that is able to effectively remove dead skin cells. At the same time it can also give way to the nutrition for the skin.
COSRX BHA Blackhead Power Liquid is based on willow bark water rather than plain water. Willow bark is a natural source of BHAs, which have anti-inflammatory as well as exfoliant properties. While I’m inclined to believe that willow bark water will not exfoliate on its own, the anti-inflammatory action contributes to an overall less irritating experience.
