Unfortunately, a closeup photo would have been more helpful for evaluating your acne scarring. As a rule, microneedling is best reserved for a final "polishing" step AFTER other more appropriate, effective and time-tested treatments are used to address rolling and boxcar scars and ice pick scars. And even if this is what indeed you need at this time, there is no hard science to prove that adding radiofrequency to microneedling, as with the Genius RF, adds any significant benefit to justify its use and expense over conventional professional medical microneedling. So exercise a healthy dose of "buyer beware" when evaluating these "bells and whistles" devices. Finally, superficial peels combining Jessner's solution with low concentrations of TCA have demonstrated efficacy for dealing with melasma and PIH. Make sure that you are consulting with a board certified aesthetic physician and avoid venues offering "one-size-fits-all" solutions for all your issues. Best of luck.
