Went for a consultation for old white stretch marks removal on buttocks and ematrix was recommended. But what is the difference between thermage & ematrix? By reading the descrip it sounds the same to me.I'm getting a good deal on ematrix though;$300/session. Also, should I look into something more 'invasive' for these stretch marks? Please see pic attached. (I searched this website and couldnt find the answer.I didnt ask at the office because I didnt know about thermage then.)Thanks!
