Didn't wear compression garment after thigh liposuction. Now I have sagging skin. Would coolsculpting or a laser help? (Photo)

Compression helps bring down swelling and allows the body to take form.  I would continue compression if you are newly out of surgery, up to 4 weeks.  If the skin doesn't tighten after 6-12 moths post surgery, you should consider other treatments such as radiofrequency tightening or surgery.  Best, Dr. Emer.

While compression garments help minimize swelling after liposuction, they do not change the quality or elasticity of your skin.  In spite of the marketing for the different machines which claim to tighten patients skin, the results are modest at best, as evidenced by your 20 sessions with radio frequency.  Loose skin is most effectively treated by removal, although it does require an acceptance of an incision line.  See a board certified plastic surgeon or several to discuss what your options may be.

Glad you recovered after the serious post op complication. I doubt either therapy will improve the skin appearance. Best top seek IN PERSON opinions.
