Forehead scar removal with autoimmune disease? (Photo)

I am not surprised that the laser treatments did not work as I have been warning my regular followers for years that these gizmos are expensive "smoke and mirrors" devices whose hard science to support their use lags woefully behind the heavy marketing and social media hype to promote them.
Revision surgery in an area such a the forehead, which is subject to a great deal of static and dynamic tension from the underlying muscles has an increased chance for the subsequent development of stretch scars and tram track stitch marks.
Subcision, which I have been performing since 1995, is an all-natural, minimally invasive means for elevating and smoothing indented scars from all causes. And once the scar is elevated, any residual, surface color and/or texture irregularities can be addressed by the use of manual Dermastamp microneedling--another perfectly natural minimally invasive technique that I have been using for nearly 25 years and also has a proven track record for safety and efficacy in all skin types.
You would be wise to consult with a board certified cosmetic dermatologist scar treatment specialist and be wary of unproven and expensive light and energy-based treatments and of revision surgery, particularly in this region. Hope this helps and best of luck.
