What will help my scar? (Photo)

I recently went to a dermatologist who burned off some sunspots and it’s left me with a circular scar. It’s been 6 months and I am incredibly upset. I have done one microneedling treatment and plan to do two more spaced out every 4 weeks but I’m worried this is not going to resolve. I need some guidance and I don’t know if the halo will help or what I should do. I’m getting incredibly impatient especially since this procedure was treated as routine and it’s left me with a scar for life.
