How can I tighten loose skin on inner thighs due to weight loss?

This is difficult to answer without pictures. A hi-definition procedure may give you better results. I recommend a combination of VASER, ThermiRF, and ultrasound which would give great results for fat removal, contouring and skin tightening, if you're a candidate. However, if the inner thigh doesn't respond to skin tightening then surgery would be the best option. I suggest seeing a body contouring specialist.  Best, Dr. Emer.

Morpheus 8 is a non-invasive skin and soft tissue tightening treatment that is consistently amazing in our patients. We use the Morpheus to exact fractional induced RF into the skin or tissue in order to tighten collagen and stimulate contraction of the tissue. For acne scars, it is quite useful to build collagen in patients who have atrophic scars but is not very productive for ice-pick scars which require TCA Cross. For tissue tightening, Morpheus is ideal for the face and neck and we often combine it with CO2 laser or Ultherapy to further enhance results. Chemical peels and skin resurfacing should be done at least 5 to 7 days after, but can be performed earlier, depending on treatment severity. Avoid exfoliating skin treatments before Morpheus and expect a period of 2-4 weeks for skin contraction to set in.
