Had cryosurgery on my face should you avoid shaving until areas are healed?

You should always consult your doctor regarding such questions (they should have sent you home with a post-operative care checklist or something similar). Since shaving is optional, and primarily a cosmetic concern, why not wait until the area is fully healed? That way you will avoid exposing the area to any irritating chemicals or mechanical stimulation. That being said, the final Word should always be from your physician.
