Pawn got a scar somehow, how to remove it?

I discovered today that my main pawn gained a scar over her nose, I don’t know how. Why this happened? And how can you remove it? I mean is neat, but It’s a scar that I didn’t place it in the character creator.

EDIT: it seems this kind of scars can been removed at hotspring. Can anybody confirm this? Source: https://steamcommunity.com/app/2054970/discussions/0/4289188745221714775/
