Too Faced Lip Injection will get you the results...as long as you can handle the burning pain
Urban Decay Lip Junkie only slightly plumps but there is no pain at all and they have like 10 colors to choose from
I totally agree with buxom! The results aren't major but it doesn't hurt the way some lip plumpers do--causing me to be a bit scared of them! Lip Fusion also didn't hurt and worked a bit better. Both have sets so you can get a bit more for your buck.
If you are feeling brave the Too Faced Lip Injection works--hurt me, I had to take it off but I've read others use it just fine.
