Radiofrequency is a “newcomer” in cosmetic plastic surgery, from the first report of wrinkle removal to the present just over 10 years. However, he has become a non-invasive cosmetic plastic surgery tool: not only the efficacy of satisfactory, adverse reactions are also less (may be the most painless laser treatment), showing good prospects for application. The principle of radiofrequency: radiofrequency is a kind of high-frequency exchange change electromagnetic wave. Skin and subcutaneous tissue in the role of charged particles in the electromagnetic wave oscillation friction and heat production, to a certain temperature dermal collagen fibers will occur immediately contraction and denaturation, and secondary continuous collagen newborn and remodeling, so the principle of non-exfoliative wrinkle similar. Collagen degeneration can be categorized into reversible and irreversible, and is related to the treatment parameters. Unlike laser or intense pulsed light, which acts selectively on a specific target group, radiofrequency heats the tissue in a three-dimensional, uniform and continuous manner throughout the entire skin layer. Because of its intensity of action and the intrinsic impedance of the tissue, to avoid differences in skin type and race, to take advantage of the above, radio frequency has become an important development direction of non-exfoliation wrinkle. The results produced by radiofrequency: Continuous collagen renewal and remodeling after radiofrequency treatment can make the treatment effect continue to be maintained months later. Skin tone measurements suggest that skin tone is at its maximum at 2 months and then gradually decreases. After a single treatment, the effect lasts for about 14 months, so it is necessary to repeat the treatment at 6-12 months. We used the Accent system (Deep Blue RF) from Alma with a frequency of 40.68 MHz and a penetration depth of up to 10-15 mm.Since this system does not have a conventional negative plate, its energy release is realized as electromagnetic radiation (EMR). During the treatment, the epidermal temperature needs to be monitored in real time. It is kept at 39-41°C, and the hot zone with the highest temperature is located in the deep dermis, not in the epidermis. This mode of action is virtually painless, with only mild erythema and edema after treatment. (Occasionally, there is a burning sensation.) Radiofrequency systems include unipolar, unibipolar, bipolar combined with intense pulsed light (or laser) and vacuum-assisted bipolar radiofrequency systems. Bipolar radiofrequency and its combination with laser and intense pulsed light have been reported to show more satisfactory results. The lack of efficacy of radiofrequency for those over 60 years of age is mainly due to the reduced sensitivity of tissues to heat.
