COSRX - yaia review for AHA/BHA Clarifying Treatment Toner

At first I thought exfoliating toners with low concentrations of aha/bha were not really effective for my skin BUT, i think this toner change my mind because i can see how my skin got a little bit better. This toner helps treat whitehead as well!! I use this in my first step after wash my face, i spray it on my cotton pad for gently eliminating dead skin cells and remove all remaining residue. So far l’ve really enjoyed this product
