I got one whole syringe of restylane in my lips. 2 days later I was in love with the size that they were, but that was just some swelling that was still going on. Nobody really noticed it unless I pointed it out. If your lips are very thin like mine, don't be hesitant about getting more than one syringe. I ended up getting another 1/2 syringe of a different filler that is supposed to be thicker (juvederm xc). I recommend everyone getting juvederm xc because it was only a tiny bit more in price (maybe $25?), so it's definitely more bang for your buck. I feel like I'm going to have a love/hate relationship as far as fillers for my lips go, because $1,600 a year for something that's not even extremely noticable is a pretty hefty price tag. I'd like to look into doing something permanent, but haven't heard good things about lip augmentations?
