About out a week and a half ago I got Juvaderm Volbella . The first time I got it (year ago) my lips turned darker around 2 weeks later but I was on a antibiotic that had that side effect for people with dark skin so we ruled out the fillers. However this time the same thing happened. There is no pain just bad discoloration that looks brownish/purple maybe? I was on vacation recently but used sunblock on my lips. Will this go away? It looks terrible. p.s. my lips bf were normal pink, no brown.
