Would ThermiTight help with loose skin on my upper arms?

In my practice, we have long focused on surgical outcomes and brachioplasty is a great surgery for people that have a lot of excess, hanging upper arm skin. Most of these people have had massive weight loss. The downside is that it comes with a visible scar when wearing short sleeves but the pts with massive weight loss usually don't mind this. But for most pts they have some loose skin with aging. In our practice, we focus on ThermiTight which is radiofrequency for heating and improving the skin quality. It is minimally invasive and pts can have some swelling or bruising afterward but it is really well tolerated. Most pts just chat with us during the procedure after the numbing medicine has been placed. I strongly recommend to my pts that they follow up with ThermiSmooth treatments (which is non invasive radiofrequency) that feels like a warm stone massage for further circumferential improvement. It usually takes 6-9 months to start seeing results. They are not as dramatic as surgery but can be really nice and without the scar.

If you have very minimal upper-arm sagging, ThermiTight could make a nice difference. ThermiTight is a radiofrequency probe that is inserted under the skin to heat the fibers that connect the skin to deeper tissues.  It also heats the dermis of the skin to produce new collagen and thereby tighten arms. I’m not sure what you mean by “PRF” but perhaps radiofrequency on top of the skin, like Thermage. I think ThermiTight is a bit more aggressive treatment but both work to some degree.  Ulthera uses sound waves to heat the skin and fibers and is sometimes a good option as well. However, if your sagging is severe you probably won’t be satisfied with the results of any of these. That’s why we sometimes combine tightening with fillers for the arms, like diluted Sculptra or Radiesse. Please find a board-certified dermatologist to evaluate the quality of your skin and degree of sagging to determine if you’d benefit from radiofrequency skin tightening with ThermiTight.
