Most patient will need at least two treatments separated over a 4-6 week period to achieve optimal results which can be seen about 12 weeks after the fully treated area. The choice is up to you as far as delaying the second treatment or not, but I would suggest getting it done so that you can get the most out of your investment. Hydrating well after the procedure and massaging the treated area regularly are important steps to reduce the risk of nodules developing and will help to get the fat cells out of the area. Regular cardio or exercise for that matter isn't important as far as how this treatment works, but if you do gain weight after going through this treatment, you may not be happy with the results. In the end, I would suggest that you go for the second treatment and be patient over the next 12 weeks. I hope you get the results you are looking for. Make sure to hydrate and massage the treated areas after that treatment.
The laser only impacts the subcutaneous fat layer and will not affect deeper structures like an abdominal mesh. It should be a safe procedure for you to explore.
This is a problem that can be associated with the applicator used in CoolSculpting in most cases. SculpSure does not require any suction and the heat tends to radiate around the applicator to the surrounding tissue providing a better cosmetic result in many cases. SculpSure does not cause "shark bites" because of this. Duration of treatment is shorter at 25 minutes because heat is more efficient at targeting fat cells.
