Is shaving bad 10-14 days (2 weeks) post Dermapen treatment for acne scars? I shave everyday and can barely get through 2 weeks.

Been doing Dermapen treatment for maybe 10 months. 5-6 treatments, noticed some affect in smoothing out my acne scars, but I feel like I'm wasting money. I am a person who cannot grow a beard, is bald, and likes to keep a Babyface. First treatment the dermatologist said "make sure not to shave for 2 weeks after this and I've been doing it. Now it has come to a point where she is saying "try and shave at the most once or twice a week between sessions."
