As people’s material living standards continue to improve, having a healthy body and beautiful appearance has become a new pursuit, but aging of the face and neck due to age or other factors has led to a steady decline in beauty value. As a result, various invasive and non-invasive cosmetic means have sprung up. Among them, ultrasonic knife technology, a combination of epidermal non-invasive, lifting effect quickly, tightening contour obvious, smoothing and fading wrinkles, stimulation of collagen cells and many other comprehensive advantages, highly favored by beauty seekers. Forehead lines, frown lines, crow’s feet? Ultrasonic knife: leave it to me! Ultrasonic knife technology can achieve the purpose of skin tightening, facial contouring and rapid smoothing of wrinkles, which can improve the skin quality and skin elasticity, and restore the skin to a delicate and shiny. The specific operation process is as follows. 1.Pre-operative operation Before the specific operation, candidates need to confirm the treatment area with the doctor, such as the face, neck or all-round. After the confirmation, the treatment consent form should be signed to understand the preoperative and postoperative related precautions.

The professional will then draw lines on the operation site to circumvent important nerves and blood vessels and apply coupling agent. 2.Intraoperative operation During the whole operation, the patient should be in a supine position to facilitate the perpendicularity between the ultrasonic knife probe and the superficial subcutaneous muscle fascia. The doctor will switch the corresponding probe according to the thickness of the skin tissue at the operation site, such as DS7-3.0mm probe with energy of 2–6J/hair and DS7-4.5mm probe with energy of 6–12J/hair. The depth of different probes varies, i.e. 4.5mm, 3mm, etc. Among them, 4.5mm targets the subcutaneous superficial muscle fascia in the cheeks, jaw margin, etc., while 3mm targets the deep and central part of the dermal reticular layer, such as the suborbital area, temporal and frontal parts of the midface. 3.Post-operative operation After the operation is completed, the candidate should clean the face with warm water and put on a medical mask after one hour under the doctor’s guidance. There may be slight redness and edema in the operation area after the operation, which will usually recover within a few hours, so hot water cleaning should be avoided as much as possible. Post-operative mask chart Do not exfoliate the treated area for at least 1 week after treatment, and do not exfoliate if sensitivity occurs, until the sensitivity of the area has subsided. A soothing, non-irritating cream or maintenance product can be used. A skin repair kit is recommended to be used in conjunction with the ultrasound facelift for ideal anti-aging results. Makeup can be applied immediately after the ultrasound facelift treatment, preferably with mineral makeup. If you need to go out in the sun, use a sunscreen with SPF 30 or above to avoid sun damage. Ultrasound together with other medical technology, you should choose this way to love beauty! Because of the many factors that cause skin aging, not only including the reduction and abnormalities of collagen and elastin, such as the presentation of the “inverted triangle” like facial aging, is caused by bone remodeling, fat redistribution plus dermal layer, subcutaneous other tissue changes together. Therefore, in order to achieve more satisfactory results, ultrasonic knife is often used in combination with other cosmetic treatments. – For example, the combination of ultrasonic knife and diluted microcrystalline porcelain is used for the treatment of severe neck and anterior chest wrinkles; – The combination of ultrasonic knife and peel-off fractional laser is used for the treatment of skin aging after photodamage, and patients can get effective improvement in wrinkles, skin laxity and skin texture; – The combination of photorejuvenation, ultrasonic knife and levulinic acid is used for the treatment of facial aging, and no serious side effects are reported, and patients can get simultaneous improvement in skin tone texture, The combination of photorejuvenation, ultrasonic knife and Lactic Acid for facial aging has no reported serious side effects, and patients can simultaneously achieve improvements in skin tone, wrinkles and facial contour. However, no matter how amazing and effective the ultrasonic knife is, it always belongs to the category of surgery and has the same risks that surgery has, so you must be careful and cautious before determining the treatment. Therefore, it is important to be cautious and careful before determining the treatment. Moreover, many domestic beauty institutions are not qualified to do ultrasonic knife, and even the machines are pirated. References [1] Zhou Luqi, Ma Gang, Lin Xiaoxi.
