Thank you for your question. Thank you for the photos. There are many things one looks for in nice lips, (overall shape, cupid's bow, fullness and enhancement, etc.). This can be done with injectable fillers. Our office likes the Hyaluronic Acid injectables for the lips, (Juvederm Ultra XC, Restylane-L, Vobella XC, Belotero, etc.). Each has pros and cons, and the procedure must be individualized to your lips. This includes the amount and placement of the injectable. Please don't over do it. Please go to an experienced, well trained injector. Price depends on the city, and who is injecting, (Physician, Nurse, PA, etc.). Remember that cheap gets expensive fast. Please call with any questions.Jeffrey J. Roth, M.D., F.A.C.S.Board Certified Plastic SurgeonLas Vegas Plastic Surgery
