Would halo laser be a good option for tightening the thighs and reducing the appearance of cellulite and dimples?

I always combine lasers with microneedling/PRP for more robust outcomes. For skin tightening, I recommend a combination of Ultherapy with RF treatments and Sculptra for skin tightening. You need a formal evaluation by an expert in body shaping and contouring to determine what is best. Nonsurgical options give only mild improvement as compared to surgical lifting. Many people have issues determining if they have skin laxity or cellulite. Lifting the skin above the indentation of the dimple can help differentiate between skin laxity and a true cellulite dimple. If the dimple goes away, it is laxity and can be treated with Morpheus8, PiXel8, Venus Legacy, and other radiofrequency devices. If it is Cellulite, then QWO or Cellfina is likely the best course of treatment. It may need to be combined with radiofrequency treatments to treat the overall area, where there may be both cellulite and skin laxity. If there is a lot of skin laxity, a Thigh Lift procedure performed at the same time as a VASER Hi-Definition ​Liposuction procedure (with ThermiRF, Renuvion, and InMode BodyTite) would give the most improvement. Other options for skin tightening would be a combination approach with Vanquish, truSculpt iD, Venus Legacy, Exilis, and Cellutone / ZWave. I recommend getting a formal evaluation with a high-definition physique expert. Best, Dr. Emer​​
