Currently i suction three times a day. But the thing is i don't like doing it. Everytime it takes me 45 minutes to complete it. I was reading some posts and some people do it twice a day. Does two times a day give you the same results?
Aim for 3. That's what I did. Every session took me between 20-30 minutes. If you can't for whatever reason, don't beat yourself up! Use Joboba oil or your favorite facial oil for easy gliding.
