Volbella is a thin hyaluronic-acid based dermal filler that gives a beautifully natural result when filling out smoker's lines. Generally, I will start with one or two syringes and let the patient wait a couple of weeks until the swelling dissipates and the product “settles.” If more filling is desired, it's easy to add more Volbella. You might also need some co-therapies, such as skin resurfacing, to get optimal results. As far as price goes, you can get a rough idea by using this site, but each practice charges differently and you usually pay more for expertise. Consulting with a few board-certified dermatologists whose results impress you will allow you to find someone in your budget range and/or work out a payment plan.
