I am deciding on Permalip size between 5 mm for my top lip and 4 mm for bottom or just do 4 mm for both? I want natural but noticeable change in fullness. I had my lips injected with juvederm two weeks ago but they didn't really get fuller, just a tiny bit. I want permanent result so decided to get implants. Also I m really worried about my smile after implants, will I be able to keep it?? It's very important to me especially considering that I work as a model. Thank you for all your help!!!!!
