In fact, whether it is Thermage, or Fotona4D or ultrasonic cannon, all belong to the category of dermatology programs, here first roughly introduce the first three. Thermage is a kind of cosmetic device that can realize stretching and tightening effect on skin with high safety, and its principle is a kind of radiofrequency technology. The fourth and fifth generations of Thermage are currently in widespread use. Fotona4D is a laser system for comprehensive three-dimensional anti-aging, which contains 2940nm/1064nm one deep and one shallow dual wavelength, SmileLiftin, Frac3, Piano and Superficial four modes of joint treatment, which can cover the skin’s superficial, middle and deep connective tissues to solve skin problems. Ultrasound Cannon uses high-intensity focused ultrasound technology to focus ultrasound energy on the subcutaneous SMAS fascia layer, superficial fascia layer, dermis layer, etc., so that the skin tissues are superimposed to heat up and a larger thermal coagulation point is formed, and then improve the subcutaneous structure of the skin from deep to shallow to make the aging collagen contraction, and stimulate the proliferation and reorganization of collagen, so as to improve the skin aging caused by the problems of loose, drooping, lines, and so on. As for wrinkle injections, its main ingredient is botulinum toxin. It reduces the movement of muscles by cutting off the nerve conduction of neuromuscular joints, so as to achieve the purpose of reducing wrinkles. Its onset of effect is usually about a week, relatively stable is two weeks, usually to be on the safe side can be two weeks after the consideration of doing these dermatological programs is better.
