Yes, I totally agree with Sandi. I wouldn't let anyone work on my face except a dermatologist. And if it was "not good" then why didn't your doctor do a biopsy? Last year I had a brown spot removed from my cheek, my dermatologist biopsied it off- meaning lightly sliced it off. Sent it to the lab, it was okay (sun damage). She advised me NOT to use antibiotic ointment on the biopsied area(not sure why) She wanted me to clean it with clear water and apply Vaseline as a waterproofer to keep moisture in, which would prevent scarring. Hope this is helpful and it heals soon!
Looked it up- here is why dermatologists do not recommend antibiotic ointment after a skin procedure:- they mention weeping blisters
