Coolsculpting now has a really effective applicator called the CoolMini. This applicator was specifically designed for use in the submental, double chin area. The treatment takes 45 minutes. Generally, 2-3 treatments are needed to achieve optimal results. Based on your photos, 2 treatments would probably be sufficient. We offer free consultations where our registered nurses can give an assessment of the area to be treated, and determine is you are truly a good candidate. Coolsculpting presents results within 2-3 months. There is some slight swelling post procedure, but not much actual discomfort. Occasionally, there may be some bruising. Kybella, (deoxycholic acid) is a product from Allergan that is administered with multiple injections under the chin and then dissolves the fat away. This usually takes several treatments to achieve best results. Once injected in the submental area, patients tend to describe a strong burning sensation. This burning subsides before long, but then the area will swell quite a lot. Most patients feel they need to stay out of public view for up to a couple of weeks post treatment with Kybella. The main reason someone would choose Kybella over Coolsculpting is that they are simply not a candidate for the latter. Various clients come into our practices who have some unwanted chin fat, but not enough to qualify as a candidate for Coolsculpting. Luckily, Kybella is an option. I hope this information has been helpful, and good luck with whichever procedure you decide upon.
