BACKGROUND: Platysma bands are one of the first signs of aging of the neck. Current theories suggest that these bands develop due to skin sagging followed by loss of muscle tone. Treatment strategies, therefore, aim to tighten skin and muscle. The aim of the present study was to demonstrate that platysma bands are due to muscular activity during the aging process and not secondary to skin sagging. This suggests a new approach to managing platysma bands. METHODS: A descriptive, prospective clinical study of 25 patients who presented with definitive, unilateral, facial palsy following otoneurosurgical treatment...

BACKGROUND: Radiofrequency technology is one of the most recently developed methods for noninvasive skin tightening and facial contouring, and works by generating thermal energy in the deep dermis. Although clinical improvements have been reported using radiofrequency devices, there are few histologic and molecular studies about the mechanisms of dermal collagen remodeling. The authors investigated the histologic effects of an ultra-high-frequency electrical field (40.68 MHz) radiofrequency device (Polargen) on collagen remodeling in hairless mouse skin and evaluated its relative molecular mechanism...

REVIEW
Karol A Gutowski
Microfocused ultrasound (MFU) generates tissue heating, which can be used for facial skin tightening as well as other areas of skin laxity. Unlike radiofrequency energy, MFU can penetrate deep into tissue without heating the superficial skin structures, allowing for higher treatment temperatures. Depending on patient factors and treatment protocols, 60% to 90% of patients can expect to see facial improvement 6 months after treatment.

Barry E DiBernardo, Gabriella DiBernardo, Jason N Pozner
Minimally invasive devices are a departure from standard laser therapies, because energy is delivered directly below the skin through a 1-mm incision. Lasers can affect such tissues as fat for enhanced disruption, coagulation of small blood vessels, and skin tightening at the right temperatures. Minimally invasive radiofrequency devices can tighten skin but can also improve neck muscle laxity. These devices can achieve results not possible with traditional external devices and, because the skin is not penetrated with energy, a much improved healing profile is seen as well...

For skin tightening, ablative and nonablative lasers have been used with various parameters full or fractionated. Currently, other energy-based technologies have been developed such as radiofrequency (RF) from mono- to multipolar, microneedling RF, and high-intensity focused ultrasound. They heat up the tissue to a clinical endpoint. Temperatures above 42°C stimulate fibroblasts to produce more collagen and some technologies produce small coagulation points that allow to shrink and to tighten the tissue with less downtime or side effects...
