What grade ptosis do I have and will thermibreast work for me? (photo)

In short, if you want to avoid scarring then you are basically limited to two options for lifting your breast: 1. Thermi is a radiofrequency device that causes tightening of the skin and can produce elevation of the nipple-areolar complex. This will not add any volume to the breast and in the best case scenario may lift about 1/2 to 1 inch but will not be permanent. 2.  Placing an implant through a small incision will add both volume and also raise the nipple-areolar complex some secondary to the rotation of the breast mound. Hope that helps, good luck. 

A vertical mastopexy would work best.  Radiofrequency will have a temporary but not permanent effect in lifting your breast.
