Which would be better
Hello, and thank you for your question enter photos. These are too very different procedures. It is light comparing apples and oranges. As a general rule cool sculpting can be utilized for generalized debulking however it will not provide any significant skin tightening. You appear to have some loose skin as well as stretch marks and an abdominoplasty is probably a better choice for long-term improvement. Understandably a less invasive procedure such as cool sculpting may be desirable however, I do not believe you will achieve your treatment goals. I recommended you followup with a plastic surgeon in your area who provides these services.
Thank you for your question and providing images. While CoolSculpting is a wonderful non-invasive procedure to aid in de-bulking the area, it would not be able to address tightening any loose skin or stretch marks; you would be an excellent candidate for a tummy tuck. I would recommend scheduling an in-person evaluation with a Board Certified Plastic Surgeon in your area. Good luck!
