Application of Non-invasive Bipolar Radiofrequency Technology in Facial Anti-aging

As we age, aging changes in facial fat cause the deep fat in the lower face to shrink and move downward, the superficial fat to swell, and the intervals between fat fibers to loosen. At the same time, the skin ages, causing skin sagging and decreased elasticity. The accumulation of subcutaneous fat in the lower face combined with the sagging and decreased elasticity of the skin leads to a bloated appearance of the lower face, a blunt jawline, and pockets at the corners of the mouth, and ultimately an aged appearance of the lower face. With economic development and technological progress, intervention and improvement of facial aging have occupied an increasingly large share in the medical beauty market. For fat accumulation and skin sagging in the lower face, conventional surgical liposuction surgery has delays and complications, so beauty seekers are more inclined to choose non-invasive treatment methods to improve facial aging. Non-invasive bipolar radio frequency technology safely applies radio frequency energy to the dermis and fat layer, stimulating collagen regeneration and contraction through thermal effects. At the same time, high-voltage ultra-short pulse waves can effectively destroy fat cells, achieving the purpose of reducing fat and tightening the skin at the same time.

Bipolar radio frequency technology generates heat by utilizing tissue impedance (resistance) to convert electrical current into heat energy. When radio frequency current acts on skin tissue, due to the impedance of skin tissue, charged particles and polar water molecules in cells oscillate and rub at high speed, causing tissue heating and heating of dermal collagen fibers. When the dermis temperature reaches 55℃~65℃, the triple helix structure of dermal collagen breaks and disintegrates due to heat, causing collagen fibers to shrink and denature, stimulating collagen remodeling to achieve the purpose of skin tightening, and its effect has been proven by a large number of clinical applications.

Due to the difference in resistance between fat cells and skin, the heat generated by fat tissue during bipolar radio frequency treatment is higher than that of skin and muscle. When fat cells are heated to above 42℃ and maintained for a sufficient time (about 15 minutes), the fat cell membrane can be denatured and the internal and external environment can be unbalanced, thereby inducing delayed cell apoptosis. Previous studies have shown that radio frequency technology has a good application effect in improving skin sagging and reducing subcutaneous fat, but all are invasive operations.

Non-invasive bipolar radio frequency devices combine bipolar radio frequency and high-voltage ultrashort pulse waves. After the treatment begins, negative pressure is generated in the handpiece treatment cavity to suck about 10mm thick skin and subcutaneous tissue into the cavity, increasing the contact area and tightness between the tissue and the handpiece, thereby effectively reducing the pain in the treatment area and increasing the penetration efficiency of radio frequency energy. After the effective negative pressure is established, 1MHz bipolar radio frequency energy is automatically emitted to evenly heat the dermis and subcutaneous tissue, stimulating collagen contraction and remodeling through thermal effects to tighten the skin. After the bipolar radio frequency emission is completed, the instrument automatically emits high-voltage ultra-short pulse waves, using the difference in resistance between skin and fat tissue to selectively target fat cells to produce irreversible electroporation, unbalance the internal and external environment of fat cells, induce apoptosis of fat cells, achieve the purpose of reducing fat cells and tightening the skin, solve fat accumulation and improve skin sagging, and significantly improve facial appearance. Immediately after the treatment, only short-term mild erythema and edema appeared in the treatment area, which disappeared within 30-120 minutes, with short work delays and high patient satisfaction.
