Non-invasive radiofrequency skin rejuvenation technology (Radiofrequency, RF): non-invasive radiofrequency skin rejuvenation technology is commonly known as electroporation, radio frequency, also known as radio frequency current, is a high-frequency alternating changes in the electromagnetic wave, 1000 times / second for the following low-frequency current; 10,000 times / second for the high-frequency current, called radio frequency. Non-invasive radiofrequency skin rejuvenation technology’s principle of action: When the current encounters impedance in its loop, it will generate heat in the part with the largest impedance, forming Selective Electro-Thermolysis (Selective Electro-Thermolysis), i.e., the radiofrequency energy selectively acts on the dermis and subcutaneous tissues, which converts it into thermal energy (65℃~75℃) to denature and contract the collagen, activate fibroblasts, and form collagen repair, and then activate the collagen to repair and rejuvenate. Fibroblasts, the formation of collagen repair, remodeling. Radiofrequency and the role of light are significantly different, light on the surface of the skin will be scattered and absorbed, it is difficult to enter the deeper layers of the skin without damaging the epidermis, they mainly act on the collagen of the superficial dermis to improve skin texture and fine wrinkles; radiofrequency, on the contrary, it is not subject to the influence of the optical properties of the skin, but with the electrical properties of the skin related to the main role of the tightening of the skin, the same has the advantage of non-invasive, no leave of absence The main effect is to tighten the skin, again with the advantage of no invasion and no vacation. Fitton (Almalasers) company produces deep blue (Accent) radio frequency treatment device, radio frequency up to 40.68MHz, so that the bipolar water molecules produce strong resonance rotation, friction heat, heating collagen, called water molecule resonance technology. It does not require the application of conductive cream or conductive liquid to realize the true sense of unipolar mode. Indications and contraindications of non-invasive radiofrequency skin rejuvenation technology: It is suitable for any optical type of loose skin, wrinkles, stretch marks, acne scars, etc., especially for mildly loose skin. 70%~80% of patients can feel a slight improvement after the first treatment, and a few of the patients can achieve the effect of laser resurfacing and face lifting. Contraindicated for patients with pacemakers and defibrillators. Non-invasive radiofrequency skin rejuvenation technology requires multiple treatments: non-invasive radiofrequency skin rejuvenation technology is a cumulative, progressive improvement process. Generally, a course of 5 treatments, each spaced about 2 weeks apart, is required for optimal skin rejuvenation. In order to maintain good results, maintenance treatments can be performed every 3~6 months after a course of treatment. Adverse reaction of non-invasive radiofrequency skin rejuvenation technology: The safety of non-invasive radiofrequency skin rejuvenation technology has been perfected, and there will be no obvious side effects after the treatment, and only mild skin congestion occurs, and even the sensitive skin can return to normal after 30 minutes. In the development of the project, it also extends from facial wrinkle removal to whole body anti-aging and stretch marks repair and many other aspects.
