Would MDF laser treatment help minimize the appearance of scarring?

From your history, you have been through the mill already, and the very fact that you are now inquiring about another laser gizmo strongly indicates that after all the treatments you have so far undergone, have so far undergone, and likely all the time and money you have already spent, you remain unsatisfied. To much Dr. Google, Dr. Tik Tok, and Dr. Instagram. Acne scar treatments do not have to be expensive nor involve all kinds of catchy-named laser and RF gizmos that are actually backed far more by marketing hype and social media buzz than any hard science. Some simple time tested techniques for acne scar treatments include the use of subcision (performed by experienced cosmetic physicians) for elevating and smoothing boxcar and rolling scars and TCA CROSS for treating ice pick scars and dilated pores. Both of these inexpensive modalities have a long track record for safety and efficacy in all skin types. I have personally been performing Field and individual subcisions since 1995 and TCA CROSS for over twenty-three years--each with consistently very gratifying results. Hope this serves to give you better direction.
