I have had this boxcar scar on the edge of my mouth for about 2 years now. It wasn’t even from acne, but from a patch of granuloma annulare and that is how it healed. I am 24 and noticing the scar is starting to pull at my lip. I am ashamed of this and it’s the only thing I can see in the mirror. Thinking about subcision and filler, however, nowhere near me offers subcision.
