I would not let them get far (barely noticeable - see first pic) without scabbing them off using a mixture of ACV, crushed aspirin, and an oil like vitamin e or an essential oil like
tea tree or ravintsara (this works great). I did see my general doctor but he did not seem very interested in looking closely at them. He said they usually go away in a year and I would be fine. OK, it's been over a year and they keep coming back. So I asked for a prescription for Aldara which he gave me.
