Dear doctors, I am considering having plasma pen for some wrinkles on my forehead that do not respond to Botox. I want to avoid fillers in the area. I've heard from a surgeon acquaintance that Plasma Pens generate underlying scar tissue. I cannot help but wonder whether, should I get this treatment on my forehead, etc. The resulting scar tissue may negatively affect the outcome of any brow lift I may get in later life? Many thanks in advance! B
