CoolSculpting’s new CoolMini applicator to treat the “double-chin” area works great; I am happy to hear you are getting such a good result! In terms the amount of treatments per area, there is no maximum, whether you are treating the chin or body. However, there does need to be enough fat to fit into the applicator, or attachment/treatment will not be possible. If you reach a point where you would still like more improvement, however do not have enough fat to fit into the CoolMini applicator, you may want to look into Kybella, an injection specifically developed to dissolve fat under the chin. Physicians may customize treatments, injecting as little or as much product needed into the targeted area, therefore there is no minimum or maximum amount of fat involved. I often treat patients first with the CoolMini, followed by Kybella injections to fine-tune results. If you are interested in pursuing Kybella treatment, be sure to consult with a board certified Dermatologist. Best of luck!
