Ultrasonic scalpel is a physical cosmetology method, which first destroys the damaged tissue. When there is a wound in our body, the repair intelligence in our body will start, and a large amount of secreted nutrients will gather at the wound to accelerate the recovery of the wound. The main components of these nutrients are collagen and hyaluronic acid. For people over 30 years old, collagen and hyaluronic acid in the body drop rapidly. If they are seriously short of collagen and hyaluronic acid, permanent skin damage, uneven skin nutrition, permanent collapse of subcutaneous nerves and skin, dark and stiff skin will occur after operation. This is the biggest risk of micro-shaping. A large amount of repair collagen must be taken orally before and after the ultrasonic scalpel, and the correct internal and external combination of ultrasonic scalpel treatment technology can be safe, reliable and lasting.
