After a double chin treatment with Belkyra, depending on the amount of fat being treated, some patients may have loose skin in the submental area and desire skin tightening to compliment the double chin therapy. To further define the jaw line and chin there are many options that can be used to help tighten up the skin. A Laser, (such as Fotona) or Radio Frequency (RF) machine (such as the Exilis or Venus Legacy) may be used following double chin treatment for skin tightening and to promote new collagen production. Dermal fillers may also be used, either alone or in combination with RF machines or lasers, to help add definition to the bone along the jaw line and chin areas.
