These are not the best options for acne scar treatment.
In my hands the best option for acne scar treatment is a comprehensive treatment that uses tumescent anesthesia, extensive subcision, fractional ablative lasers, excision of pitted and box scars and PRP. Delayed use of filler and lesser aggressive treatments may be used after one month if necessary. Our average improvement after a "one-and-done comprehensive treatment" was 72% on our first 114 patients. We have now performed over 700 of these procedures and feel it is the best approach for treating a variety of acne scars. Other methods help, but take many treatments and it is often difficult to achieve even 50% improvement. I invented and patented a tool that I use to perform the extensive subcision.
I would prefer injections of fillers for the deep scars and eMatrix to improve your acne scars. Please consult an expert. Best, Dr. Green
