Retrospective study on non-ablative radiofrequency for skin rejuvenation
Abstract
In this article we evaluate the efficacy of radiofrequency (RF) on the laxity of the shin, thanks to a clinical retrospective study on 150 patients treated in a period between september 2004 and december 2005. We report the results obtained with two different RF devices namely mono or bipolar, as well as, the side effects, advantages and disadvantages of such a method.
Lasers and light-based treatments are extremely useful and now standardized techniques in the management of different stages of photoaging. To obtain the most successful results, protocols involving single or combination systems can be used, depending on skin photodamage. In the last years, the trend is to choose noninvasive or minimally invasive treatments, with the aim of reducing the risk of side effects, complications, and downtime. Selective photothermolysis obtained with lasers and with intense pulse light, which is presently considered the most suitable technique by a growing number of authors, is an extremely valid procedure, in particular in types I and II, according to the Glogau classification. Photodynamic therapy is another effective tool in photoaging treatment, especially in the presence of precancerous conditions. In mild and severe photoaging, ablative laser resurfacing is a particularly successful technique, although requiring a very skilled hand. The new systems, such as fractional photothermolysis, seem to be the very next future to face up to resurfacing procedure with high efficacy and less risks. Obviously, lasers and light-based treatments alone might not be sufficient to control all aging symptoms. For this reason, any another treatment (botulinum toxin, filling agents, chemical peels, systemic and topic antioxidants) can be used in combination to improve the final clinical outcome.
Unlike other nonablative devices that presumably stimulate neocolagen formation via various targets in the superfacial dermis, this device is a true "biostimulator," which causes immediate shortening of the collagen fibrils and neocollagen formation by a probable secondary wound healing response [11]. The results achieved by the ThermaCool have been extremely impressive and will almost certainly improve as the treatment methods are further optimized. many patients do not want the cost, risk, and downtime associated with surgical procedures, and this gives them an alternative. Minimally and noninvasive procedures have envolved as technolgy patients. We have always attempted to reduce tha teltale signs of surgery, but the patient-driven trend is avoidance of an "operated" look.
The methods additional or substitution for the surgery of facial skin ageing are dramatically rising before 40 years. These methods are addressed more to the wrinkles and others signs of aging skin. They can constitute a door of entry in the aesthetic treatments and needs a professional approach. These noninvasive methods (within the meaning of the incision) can present complications this the more so as the tendency is with the vulgarizing and with under considerations of the initial diagnosis and the treatment itself. The devices of thermal effects consist of lasers, pulsed flashlamps and radiofrequency. The objective of this development is to consider the bonds, which link the initial diagnosis and the proposal for a treatment by considering side effects and complications of each method.
