I really like this toner! I only use this at night with the matching cleanser and I feel like together they have kept my breakouts and clogged pores at bay. My facial-girl recommended me doing a salicylic routine at night because I have pretty bad congestion in my t-zone and overall very classic combination skin. This toner definitely is much stronger and more drying than the rose water/witch hazel one I use in the morning but I use a heavier moisturizer at night so it doesn't make my skin flakey or overly dry. I don't think I could handle using this twice a day, but I don't feel like I need to because I don't really get cycstic acne, just cogged pores.
