RF skin tightening treatments can be carried out every 2 to 4 weeks.  Some clinics will offer a radio frequency skin treatment course, maybe a course of 6 to 8 treatments over a 12 week period to achieve skin tightening.  The collagen stimulation created from radiofrequency can take up to 4-6 weeks to be noticed or felt, so more often less is more for those clients who want to tighten their skin!
