Undeniably, ultrasonic scalpel can change the face of aging to some extent. Let the skin aging situation improve, its main battlefield is in the fascia layer, and other things that promote collagen regeneration and recombination are behind. When we are young, the deep fascia of the skin is very elastic and supportive. It can firmly hold several fat pads on the face, such as the girl's risorius, full temples and tight facial contours, which is a moving picture of collagen. Years, circumstances, pressure, etc. They all kill pigs and keep cutting their skins. The epidermis, dermis, subcutaneous tissue, fascia and muscles that support the face are losing ground, and aging is inevitable. The fascia layer is the most difficult as a support. Its ability to fix the fat pad decreases. Even if the first few layers are fine, they will not be "shaped" with the fascia. If the muscles behind them fall off the chain, it is really not "shaped"! Therefore, the ultrasonic scalpel took a good look at this and activated the fascia without "molding". The ultrasonic scalpel is like sunlight passing through a magnifying glass, bringing energy points into the fascia layer and stimulating it to restore support. If the contents of collagen and hyaluronic acid under the skin are low at this time, the skin will be directly necrotic and solidified when it meets the high temperature of 60-75℃, and it will be "welded" with the fascia layer, ranging from short retention time after treatment to poor curative effect, and then to serious problems such as facial burn, dry skin, pigmentation, uneven skin surface, subcutaneous nerve injury, permanent skin collapse and stiffness. Did you do it, BB? Some people may retort that a large amount of collagen solution will be taken orally before and after the operation to prevent this from happening, but everyone absorbs collagen differently, which is definitely not 100%. Effective measures. As mentioned earlier, deep tissues such as fascia are burned by focused ultrasonic scalpel, which is simply burn. Can you just add some collagen? Who has seen collagen after burn?
