Is there a maximum number of coolsculpting procedures you can do to one area? Such as these cool mini?

If you like the results thus far and still have enough tissue to allow the applicator to attach then it is ok. Please remember that it can take up to 90 days to see full results so perhaps make sure you are waiting for full results before doing another. Initially Zeltiq only recommended directly under the chin but recently educated our team that the applicator can be moved slightly to the lateral area so perhaps see if this is an option for you. In short, there is no documented contraindications to multiple treatments if spaced out and there is enough tissue from the data currently available. 

Hello and thank-you for your question
 For optimal results, 2 treatments are generally required. The treatments are separated by 4-6 weeks. Treatments are planned using templates of the CoolMini applicator. For fat localized to the sub mental chin, a single applicator per session may be required.  If there is significant fat more laterally in the neck, 2 or 3 overlapping applicators may be required to produce the optimal result.  We also offer Kybella and often use the two to develop customized a non-invasive alternative to surgical options. I would visit with a board certified plastic surgeon in your area who offers all these options to discuss what is best for you.

There is no maximum number of coolsculpting treatments that can be performed in an area, each treatment gives you about a 20% reduction of fat and most people require at least 2 treatments per area. Some people may benefit for more than 2 treatments but make sure you give the area enough time to see full results so you aren't wasting your time or money, you may want to save it for another body area.
