MFUS, in opposed to HIFU, offers more accurate energy delivery due to advancements in the system that better meet the needs of skin laxity. That's why the MFUS device may be ideally adapted to treat the problem of skin laxity. In addition, it is capable of delivering deep heat energy into the superficial dermis and subdermal connective tissue at tissue planes to induce more extensive collagen remodeling . Micro-focused ultrasound (MFUS) was introduced in 2009 to offer precision-focused thermal injury zones at therapeutic depths larger than those available with the previous technologies. In contrast, shallow frequency waves generate focal thermal injury zones (TIZs) across deeper layers. The depth of penetration is determined by the frequency of the waves, with higher frequency waves generating a lower focal injury zone. So at the focal point of the beam, friction among tissue molecules creates thermal damage. Ultrasound waves penetrate tissue, causing molecules to vibrate at just the focus of the beam. And these have recently been developed to treat subcutaneous lipolysis. Studies reported that the acoustical energy of high-intensity focused ultrasound (HIFU) is considered to penetrate tissue far deeper than laser or RF radiation. Unfortunately, less intrusive procedures have a history of poor efficacy, uneven clinical outcome, and a shorter-lasting tightening effect. When compared to ablative laser skin rejuvenating or surgical face lifting procedures, the advantages of this method are indistinct: minimal downtime, relative safety for usage on non-facial areas and skin color, and a favorable side effect profile . Thus, it promotes healing wounds and neocollagenesis without causing epidermal damage or clinical recovery. Additionally, heat penetration up to 2-4 mm into the skin is needed to achieve minor skin tightening produced by RF devices. Traditional ablative laser skin rejuvenation is associated with a lengthy healing period and the possibility of delayed dyspigmentation. Through the administration of controlled dermal heating, treatments, including fractional and ablative laser skin resurfacing and radiofrequency (RF), offer varying tissue tightening levels. However, a broad range of nonsurgical procedures has emerged as an alternative to surgery over the last decade. Surgical lifting procedures have typically been used to treat facial and neck skin sagging and laxity.
Better improvements rates have been reported by both patients' self-assessment and clinical investigators' evaluation. MFU treatment can activate deeper tissues without causing injury to the epidermis, which sets it apart from all other skin tightening methods. Patients report no considerable side effects, and the results were also long-lasting. The literature study results revealed that significant improvements in the overall aesthetics of sagging of the mid and lower face could be accomplished by using a micro-focused ultrasonic treatment plan. In addition, all of the patients were evaluated to report the harms and risks associated with MFU treatment. The goal was to analyze and examine the effects and benefits of MFU treatment to improve the skin. After a thorough evaluation and following the exclusion and inclusion criteria, 10 full-text articles were relevant to the study. A total of 139 articles were extracted from the PubMed and Science Direct electronic databases. This literature study was intended to find the role and efficiency of using micro-focused ultrasound therapy in male and female patients aged 35-65. Micro-focused ultrasound (MFU) has been recently introduced as a novel energy modality for skin rejuvenation to produce a more significant wound healing response at various levels, including strong collagen remodeling and long-lasting clinical response.
The demand for non-invasive skin-tightening techniques is continuously on the rise, as now numerous patients seek safe and effective alternative body, neck, and facial aesthetic surgical procedures.
