Real lip filler patients on RealSelf.com report paying an average of $750 for lip fillers. At Las Vegas Plastic Surgery, the cost of lip fillers varies depending on the type and amount of filler injected. We price dermal fillers by the syringe, so your total cost will depend on how many syringes you need as well as which specific formulation we use. The best way to get an accurate estimate is to consult one-on-one with an injector. After assessing your current look and talking over your goals, your injector will be able to provide specific pricing before moving forward with your treatment.
