I'm trying to figure out why I am getting infection in my lips after filler. Ihave gotten my lips done 4 times. The first two times with juvederm (no complications), next two times with restalyne (one time was perlane). My lips became extremely [RS bleep] (particularly in one side of my lip) Some cosmetic physicians are telling me not to get it again, but I don't see how I can become resistant suddenly? I'm due to get juvederm again in October, should I?
