Pulsed radiofrequency for periorbital sagging: a comparative study

Introduction: Wrinkles, sagging, changes in texture and skin pigmentation in the periorbital region are common complaints in dermatologic practices. Several treatment options, including fractional radiofrequency, which has been shown safe and effective, have been described.
Objective: To compare outcomes and side effects after the use of two types of electrodes coupled to a radiofrequency device, used for rejuvenating the eyelid region.
Methods: A comparative, randomized and blind clinical trial was carried out with patients bearing aging in the periorbital region. The patients were treated with two different electrodes (called standard tip and Lima 8 tip), which can be coupled to the same radioelectrosurgery device. The variables investigated were sagging, wrinkles, texture and firmness of the treated skin, in addition to the presence of adverse effects. Thirty days after the last session, patients answered to a satisfaction questionnaire, having been photographed for clinical assessment.
Results: The patients treated with both tips experienced considerable satisfaction with the improvement of sagging and wrinkles. The variable firmness presented worse satisfaction indices, with a disadvantage for the standard tip. Important edemas emerged after the use of both tips; nevertheless ecchymosis occurred most frequently and lasted longer with the Lima 8 tip. Hyperpigmentation was more frequent and longer lasting with the standard tip, however without statistically significant difference.
Conclusions: The two tips were equally effective for the treatment of sagginess, wrinkles and skin texture in the periorbital region. The patients treated with the Lima 8 tip had higher satisfaction indices regarding the skin’s firmness, experiencing a higher incidence of ecchymosis, as well as a longer duration of that side effect.
