Subdermal Radiofrequency, Malar Bags, Efficacy


The purpose of this study is to present our experience in the treatment of laxity of the malar region using Subdermal induced heat (S.I.H.) technology, a new technology that uses cannulae to bring under the skin monopolar radiofrequency (RF) to treat malar defect in a minimally invasive, non-surgical way and produce an aesthetic improvement.


Ten patients with edema, malar bags and malar festoons had two treatment sessions with S.I.H. technology using a 5 cm cannula at a temperature between 45 and 50 degrees. The overall duration of bilateral treatment was 360 seconds and the time required for each session was no longer than 20 minutes. No postoperative care was required.


All the patients in the study showed an aesthetic improvement in the malar region, in relation to the severity of the blemish, through collagen contraction and the production of neo-collagen by fibroblastic stimulation. All patients were able to immediately return to their normal routine. Although the results were gradual, patient satisfaction was remarkable. There were no complications during the study.


This new therapeutic proposal that uses S.I.H. technology allows a safe, non-invasive aesthetic improvement in these patients with excessive skin laxity of the malar region.
