I am thinking of having Juvederm injected into my smile lines to smooth out the folds. I am a first timer with fillers and I am worried about the possibility of bumps and the filler becoming hard or moving to a different area after it is injected. Can that be corrected if it happens? Which would you recommend, Restylane or Juverderm. I am a 38 year old African American. Thanks Juvederm vs Restylane, which is better?
