Monopolar RF lifting evidence for Lower face / jowls

Abstract summary (English) BACKGROUND: Recently, radiofrequency (RF) devices have been introduced and commercialized for nonablative procedures in dermatology and plastic surgery for the treatment of age-related rhytides and lax skin. OBJECTIVE: The objective was to assess the efficacy and safety of a novel RF device (Accent, Alma Lasers, Ltd, Caesarea, Israel) for the treatment of rhytides and lax skin. METHODS AND MATERIALS: Sixteen female...

Clinical Trial, Journal Article

Abstract summary (English) BACKGROUND AND OBJECTIVE: Non-ablative monopolar radiofrequency technology delivers heat to the deep dermis and subdermal layers of the skin to improve facial laxity. The purpose of this study is to evaluate the multiple pass, low fluence treatment algorithm for lower face laxity. STUDY DESIGN/MATERIALS AND METHODS: Sixty-six subjects with moderate facial laxity were treated with a maximum of 5 passes over the lower...

Evaluation Study, Journal Article, Multicenter Study

Abstract summary (English) Non-invasive procedures for tissue tightening and elevation are new frontiers in dermasurgery. Current methods for achieving a "nonsurgical face-lift" include radiofrequency and infrared light devices which disrupt non-covalent collagen bonds and stimulate collagen production. This study evaluated a novel treatment protocol designed to achieve a nonsurgical face-lift with electrical stimulation of muscle.

Comparative Study, Evaluation Study, Journal Article

Abstract summary (English) BACKGROUND: Radiofrequency application through a proprietary device has recently been used for facial tissue tightening. Uniform volumetric heating of the dermis is created by passage of electrical current, while protection of the epidermis is maintained by concurrent cryogen cooling. OBJECTIVE: To objectively quantify the effectiveness of volumetric radiofrequency application on the face, we treated 10 patients on...

Clinical Trial, Controlled Clinical Trial, Journal Article

Abstract summary (English) The medical use of radio frequency (RF) is based on an oscillating electrical current forcing collisions between charged molecules and ions, which are then transformed into heat. RF heating occurs irrespective of chromophore or skin type and is not dependent on selective photothermolysis. RF can be delivered using monopolar, bipolar, and unipolar devices, and each method has theoretical limits of depth penetration.

Journal Article, Review

Abstract summary (English) Bipolar radiofrequency (RF) is capable of delivering higher energy fluencies direct to the dermis through a needle electrode. This produces heat when the tissue electrical resistance converts the electric current to thermal energy in the tissue. A 38-year-old man visited our clinic for reduction of submental fat deposit, but otherwise in overall good health.

Case Reports, Letter

Abstract summary (English) BACKGROUND AND AIMS: Cosmetic rejuvenation of the perioral area can be challenging due to a mix of skin laxity and volumetric loss. Current techniques including fillers, neurotoxins, and non-ablative and ablative resurfacing have several drawbacks and can create a stiff, box-shaped, unnatural appearance. Aside from filler, these techniques do not address deeper volume deficiency.

Journal Article

Abstract summary (English) BACKGROUND: Aging of the face and upper neck is a complex process characterized by loss of collagen and elastic fibers, resulting in clinical skin laxity. Noninvasive interventions such as monopolar capacitively coupled radiofrequency (MRF) have gained popularity, offering a safer and more convenient alternative to traditional surgical face lift. The latest MRF device features larger tips, vibration, cooling, and...

Journal Article

Abstract summary (English) INTRODUCTION: Radiofrequency has remained a staple procedure for the treatment of skin laxity as therapeutic heat thresholds effectively promote collagen remodeling. Nevertheless, comprehensive skin tightening involves both dermal and hypodermal collagen remodeling. However, transcutaneous radiofrequency is unable to deliver consistent and measurable temperatures to the hypodermal layers.

Journal Article

Abstract summary (English) OBJECTIVE: To use 3D photography to evaluate the clinical efficacy of a novel radiofrequency delivery device used to improve the appearance of rhytids and laxity of the face and neck. STUDY DESIGN: Forty-nine subjects received a total of two radio-frequency treatments to the face and neck one-month apart. The novel radio-frequency delivery device was used to heat the dermis between 41-43°C for five heat cycles.
