My daughter (18) had 2 moles removed yesterday at dermatologist. One on back of neck, one on her right upper mid-drift section?

This morning noticed a light brown spot above above & beneath the removed mole. I was freaking out. He injected her with a numbing agent, used a curved blade to remove them, then applied a kind of dark stuff on a long Q-Tip. I asked if I should put any antibiotic cream he said no. I just don't feel right I feel bad enough maybe should have left them alone. I just wanted to do right by my daughter. I know they might scar some but I'm hoping to lessen that possibility with whatever I can.
