I have had treatments with 1.5 mm needles. I havent seen the results I want.
It is not the microneedling method, its finding what the scar is doing. Is it bound down, if so, subcsion is the treatment of choice. The very first step is scar assessment by a Board Certified Plastics or Dermatologist. If it is bound down, vertical manipulation of the scar will not do anything, its horizontal vector delivery of the needles that will work. See an expert near you to assess your scar type, then go from there. Surgical intervention with subcision of surgery with elevation maybe needed, followed by fully ablative lasers.
