Medical Treatments For Tightening Loose Skin After Weight Loss – Thank you https://totalshape.com/lose-weight/how-to-tighten-loose-skin-after-weight-loss/
There are several types of body contouring surgery available for people who have gone through massive weight loss.
I’m not recommending any of these, as you’ll have to talk to your doctor and plastic surgeons about whether there are viable options.
Body contouring surgery often starts with liposuction to remove excess fat, but it can often leave hanging skin immediately after the surgery [9].
In some cases, surgeons will immediately put a plan in place to tighten skin.
Dr. Cameron Rokhsar, cosmetic surgeon and dermatologist, recommends ThermiTight as a good non-surgical procedure to tighten skin. It uses radiofrequency to create heat in the dermis for immediate results.
It might involve a second surgery at a later date, but this can be a highly effective and fast way to deal with the problem.
