Cosrx AHA/BHA Clarifying Treatment Toner is an affordable option from Cosrx that delivers solid value for oily and combination skin managing ongoing texture and mild congestion, not for those needing intensive acne treatment (pair with a dedicated BHA serum for that). The inclusion of Salix Alba (Willow) Bark Extract provides natural salicin source for mild keratolytic action. Best suited for oily and combination skin managing ongoing texture and mild congestion, not for those needing intensive acne treatment (pair with a dedicated BHA serum for that).
