Frankly, I am not at all surprised, nor would my regular followers be, that there was little success with the treatments tried here. I have been informing readers for years that the hard science to back up the use of expensive "bells and whistles" fraxel lasers and RF gizmos lags well behind the heavy marketing hype and social media buzz that promotes them. Sorry. On the other hand, there are several techniques for treating acne scars that have stood the test following decades' of use for both safety and efficacy in treating acne scars in all skin types. Field Subcision is for elevating and smoothing large areas, such as the cheeks or the temples. Individual subcisions, which I have been performing since 1995, is a proven technique for elevating and smoothing distinct boxcar and rolling scars. TCA CROSS, which I have been performing for over twenty-four years, is for addressing ice pick scars. And, finally, once the aforementioned are performed, professionally performed manual microneedling (no need for the added expense and risks of RF microneedling) can be used to better blend the treated scars, in both color and texture, with the surrounding normal skin. Hope this helps and best of luck.
