Hi, Dr. Lam! I'm interested in augmenting my lips permanently with your help, but do not wish to do so with Sili. I don't think injections will look good on me since I have extremely thin lips. I've been researching for a while about lip roll procedure, which leaves stitches inside the mouth, producing no visible outer scar. Do you also perform this? If you do, can you give me a ballpark estimate? Thanks in advance.
