Tighten pores to prevent a recurring cycle of blackheads with the COSRX 2 in One Poreless Power Liquid; a dual-action formula that chemically exfoliates pores with BHA, whilst tightening them with Tannin. Aside from these primary functions, the liquid is effective in cooling down skin temperature and controlling excessive sebum production.
