Great question. Intensif has become one of may favorite devices for facial rejuvenation because it is effective and reliable with down time of only an hour or so. I almost always combine it with PRP (platelet rich plasma) treatments to effectively stimulate a thickening and tightening to the skin of the face, neck, decollete, and hands. Most often, I use a simple 8-point lidocaine nerve block to make the treatment more comfortable. During Intensif, the 25 gold-tipped, non-insulated micro needles are advanced smoothly into the dermis (2.0 - 3.5mm, approx 1/8") at which point the radio frequency energy is released into the dermis. Although it is conceivable that facial fat could be effected, facial fat is considerably deeper than the target of the treatment depth, and it has not been my observation, that facial fat is adversely affected.
