First, skin tightening wrinkle skin tightening wrinkle is the earliest application of radio frequency technology in the field of skin beauty, the most used part. A large number of clinical studies on the clinical efficacy and safety of radiofrequency for skin tightening and wrinkle removal have been prospectively evaluated, suggesting that radiofrequency technology can not only tighten the loose skin of the face and neck to achieve different degrees of rejuvenation of the skin of the face and neck, but also have a good clinical effect on the buttocks, abdomen, breast and other parts of the sagging skin and wrinkles. These include the reduction of periorbital, forehead, and inter-brow wrinkles, long-lasting lifting of the skin in the frontal eyebrow area, and tightening of the skin in the upper eyelid area, as well as reduction of sagging skin and wrinkles in the zygomatic area, sagging skin-like saccades on both sides of the corners of the mouth, perioral vertical lines, horizontal lines on the neck on both hands, both upper extremities, the lower extremities, the buttocks, the abdomen, and wrinkles in the breast, as well as reduction of abdominal distension (including stretch marks), and so on. Research has confirmed that radiofrequency skin tightening is safer, only mild, temporary erythema and edema in the treatment area, and scarring rarely occurs. Second, acne treatment Studies have shown that after radiofrequency treatment, skin tightening, skin pore size acne reduction. This may be related to the thermal effect of radiofrequency and its antibacterial effect. However, due to the multiple pathogenic causes of acne, only targeting Propionibacterium acnes treatment has limited efficacy. Furthermore, high-frequency current can only inhibit the growth of Propionibacterium acnes to a certain extent. Therefore, although radiofrequency is a new, safe and effective complementary and alternative treatment for severe acne, it has no obvious advantage over traditional treatments such as topical internal antibiotics. Third, scar repair Radiofrequency treatment of acne scarring is more acceptable to patients than traditional grinding methods or microdermabrasion treatment of scarring. Radiofrequency treatment has a certain effect on hyperplastic scarring, radiofrequency generates heat energy in the dermal tissues, stimulating the collagen fibers to contract instantly, and a series of physicochemical effects are produced by the heat of the tissues to enhance the metabolism, promote the fibroblasts to produce new collagen fibers, and to make the atrophic and depressed scarring Parts of the dermal collagen layer proliferation, purpura tissue remodeling, restore skin elasticity, so that the skin becomes full and smooth again. Fourth, fat reduction It has been reported that radiofrequency technology can be used for breast reduction, abdominal fat reduction and other treatments. Radiofrequency technology helps to enhance the destructiveness of adipose tissue, but also can be a non-invasive, non-adipose tissue necrosis to promote the transfer and reduction of fat storage tissue. An ablative effect of RF on subcutaneous adipose tissue has been observed using real-time ultrasound and magnetic resonance imaging. Human cellulite-like tissue after radiofrequency treatment, adipocytes release glycerol increased and its histological shape, volume and composition and collagen complexes and other corresponding changes, resulting in fat reduction and skin tightening. Fifth, hair removal radio frequency and intense pulsed light technology combination for hair removal, can be applied to a variety of skin colors and all colors of hair, the effect is good, of which black hair is the best, and skin color does not affect the efficacy of treatment, suitable for the treatment of darker skin type of people’s hair removal, as well as copper and white hair removal, which is the single use of laser or intense pulsed light hair removal difficulties. In addition, for the removal of residual hair after laser hair removal, radiofrequency treatment is a good remedy. Tip: Radiofrequency technology can be used in combination with other methods such as laser resurfacing, neck debridement or botulinum toxin injections to achieve better cosmetic results. The clinical efficacy of radiofrequency combined with tazarotene topical treatment of primary cutaneous amyloidosis is significantly better than that of tazarotene alone; it is especially suitable for the treatment of mossy amyloid lesions, which directly removes the diseased tissues of the skin and amyloidogenic proteins deposited in the dermis without the survival of carbonized necrotic tissues. Radiofrequency technology will be the traditional skin cosmetic methods to more safe, effective and minimally invasive process development, in cosmetic dermatology has a broader application prospects.
