Ok, I have Profound, eMatrix, Themage, INFINI RF, and access to secret RF. Profound is by far the worse device for skin tightening out there. Why? Needles not sufficient, angled delivery, long down time, and bruising that may last 10 days. No conflict of interest, but INFINI RF is infinitely better than PROFOUND. No pun intended. Syneron Candela makes great devices - V BEAM, 755 alex , Max Pro, eMatrix, but Profound is profoundly outdated and in all truth, crap.- no pun intended again. All the best, with no prejudice ( as I am an advisor for Profound), Dr Davin Lim Laser and aesthetic dermatologist ( who tells it as it is)Brisbane, Australia.
