I am planning on having a series of 6 microneedling sessions to improve my rolling and boxcar acne scars. I have done a lot of research on this, and I came across a very exciting article in the Journal of Cutaneous and Aesthetic Surgery. It says that the plastic surgeon administering the treatment performed microneedling and directly followed it with .05% tretinoin, but washed it off after 30 minutes. Is that safe to do?
