The CosRx AHA/BHA toner has become one of my staple toners;it doesn't irritate my skin and the low concentrations of chemical exfoliate are usually not harsh enough to aggravate sensitive skin. This is not a replacement for AHA and BHA, and also creates a great base for use of Vitamin C.

Pros:
>packaging (clear bottle so you can keep track of what's left and super fine mist dispensary) and clear instructions
>no strong fragrance
>smoothing
>trouble skin/pimple and oil control
>no irritation experienced
