Hello, in class someone pointed out that i have smile lines and if i don't treat them while im still in my 20's, by the time im 30 theyll be terrible grooves:( since i havent done aanything yet, should i start with a HA filler and then Sculptra or Bellafill? I know both stimulate collagen and the later lasts much longer, but does Sculptra cause more lumps or no..? Both are pretty safe?
