Scars on cheek. Have done subcision + filler twice. No result. 2 x Profractional and 1 x Smartxide. Still no results. Derm (and 1 PS) have suggested punch excision (not scalpel) but I'm terrified after reading horror stories about it and having another PS tell me that only about 30% of acne scar excisions succeed. Is this true? What else should I consider? TCA cross is also worrisome to me. Are my scars to broad for it? What about derma sanding? Please help me with my decision. Thanks!!!
