Microneedling can heal many types of scarring. It has worked amazingly for me to the point that I am no longer psychically scarred from my botched transplant and although I probably won't get surgery, it is good for hiding surgical scars. I am currently using it on my adam's apple incision which is all but obscured after a couple of months. Don't fail to try this as it starts working on scar tissue immediately while any hair effects take more time. I cannot effuse enough about how wonderful microneedling in. It's the beauty treatment of the century and most people remain unaware of its uncanny power.
