Subcutaneous Radiofrequency Microneedling for the Treatment of Thigh Skin Laxity Caused by Weight Loss: A Case Study.

Radiofrequency (RF) microneedling has been used to reduce skin laxity, due to aging, on the face and neck. Our objective for this case study was to evaluate the use of RF in combination with microneedling to nonsurgically improve skin laxity, a result of significant weight loss, on the thighs of a 39-year-old woman. Two sessions of subcutaneous RF microneedling were performed five months apart on the patient's bilateral medial thighs. Laxity was graded before the first session and two months following the second session using the Hexsel and Dal'Forno Severity Scale of Cellulite. Upon visual evaluation, the appearance of cellulite and skin laxity was improved, with a five-point improvement on the Hexsel and Dal'Forno scale at two months after the second treatment. Laxity and depth of depressions showed the most improvement. Our patient reported satisfaction with the results. RF microneedling might offer an effective alternative to surgical correction of skin laxity. Further research is needed to explore the expanding applications of RF microneedling in aesthetic medicine.
