Possible cut on tortoises face?

[jenHM]

Hi all! I'm a tortoise noob, and I was wondering if anyone could help me out. I think Trudy has some kind of wound on her face, but I'm not sure. Today we went out in the backyard for a few hours. I always watch her when we're outside. She just walked around in the grass. When I picked her up to take her inside, I noticed a dark red substance on her face that looked like blood. I didn't see anything happen that might have hurt her while we were outside, but I'm not sure if it was there before I took her out. I gave her a soak and gently cleaned it with warm water and a soft toothbrush. It didn't seem to bother her. Now it looks like these pics. Is this something I should be concerned about? If it's a cut, is there anything I should do besides clean it with water or should I leave it alone?
For reference, she's a rescue redfoot. I've had her 3 years, and she's probably 16-17 years old. She has had no other health issues. I've never noticed anything else weird on her skin or shell.

It should heal up ok. Just keep it covered with Neosporin to keep flies off.

@Yvonne G Thanks! I read somewhere else that I shouldn't put Neosporin on it, but there's really no consensus.
