The results of most procedures are significantly influenced by the expertise of the person doing the treatment. In the right hands, medical micro-needling is an excellent procedure for improving the appearance of acne scars. In my office we use the ProCell Therapies micro-needling machine for a more even pattern of needle penetration in the skin. We also apply growth factor serums derived from human stem cells to further enhance the results. For the best results it typically takes a series of treatments, each one month apart, and then a waiting time of several months for the full effect.
