Scar removal on my arms - what can I do to get rid of it? (Photo)

Sorry this happened. You would be wise to consult with a board certified cosmetic dermatologist scar specialist about the use of manual microneedling (no need for the added expense and rsks of RF microneedling) accompanied by the application of pigment enhancing medications, such as topical tyrosine and lanatoprost. Be wary when offered all kinds of relatively expensive "bells and whistles" gizmos, such as fraxel lasers or RF devices, as the hard science to support the use of these devices lags woefully behind the heavy marketing hype and social media buzz that surround them. Hope this helps.
