In my office we use Juvederm,You should start out with maybe 1cc of filler and go from there. You do not want to overdo too much filler in the lips. It also depends on the look you are going for too. You can always add more filler to the lips if needed. Just remember if you are going to do your lips and you do not want to bruise you should not take any aspirins or anything that will thin the blood since brusing can occur.
Belotero or restylane silk do great in the lips and is easy to get. It lasts about 4months and looks very natural.
