N.S.
I find that what works really well is just washing atleast 2x/day with one of those apricot exfoliating washes. Then I use the astringent before bed so the oil does not sit there. If it gets really bad I spot cover the bad areas with oxy before bed. But it seems to help alot to keep the pores clean and closed as much as possible. I know sweat in the summer is unavoidable. Good luck and hope it works!
