COSRX’s Two in One Poreless Power Liquid is an alcohol-free toner that cleans and tightens pores. Willow bark water is added to this lightweight formula to combat symptoms of acne by dissolving the sebum and dead skin cells that can get trapped inside pores, while hyaluronic acid offers deep, long-lasting moisture. Perfect for people who suffer from enlarged pores and pore congestion in the T-zone area or on their cheeks.  Tannin helps tighten the pores and refine skin texture. Parben free.
