Your toner and setting spray has two things in common: denatured alcohol. So if you haven't dove in and bought that $20+ setting spray or if you want an inexpensive alternative, I have your solution. The denatured alcohol closes your pores thus helping reducing the oil on your face. After applying your makeup, spray some of your toner on your face and watch the results. It behaves just like a setting spray.
That's it for now!
