A clinic owner asked me how many sessions her patients actually need. I pulled 200 treatment records to find the answer. The average was 4.2 sessions for acne scars and 3.1 for anti aging at 4 week intervals. The data showed that patients at 4 week intervals had 23 percent better collagen remodeling than those at 6 week intervals.
Needle depth selection depends on the condition being treated. For superficial concerns 0.25 to 0.5 millimeters is sufficient. For acne scars 0.5 to 1.0 millimeters. For deep scars and wrinkles 1.0 to 2.5 millimeters.
