2 years ago I got 0.5 ml and it got infected, I got no treatment. My top lip became scarred due to the ulcers and bleeding. I tried to get them re filled straight away as they were uneven but it dropped below my lip as if it couldn't hold the filler. I got them dissolved but you can still see a small scar and shading discolouration. If I get more filler to even them, will it drop again? Is there anything else I can do to help this oddness? Please help!!!
