Fiber optic lipolysis is a new type of lipolysis method, which can precisely locate the lipolysis area and use plasma photothermal action to act directly on the subcutaneous fat to liquefy the subcutaneous fat, and then gradually metabolize and absorb the liquefied fat through its own metabolism to achieve the effect of local lipolysis, fat elimination, beauty and shaping. However, the following risks may exist in fiber optic lipolysis: 1. postoperative hematoma and pain: fiber optic lipolysis needs to dissolve the subcutaneous fat tissue, so hematoma and pain may occur after surgery; 2. damage to nerves and blood vessels: there are peripheral nerves and blood vessels in human fat, so when performing fiber optic lipolysis, it is inevitable that nerves and blood vessels will be damaged, and the more the amount of fiber optic lipolysis, the more serious the nerve damage will be; 3. skin Looseness: After fiber optic lipolysis, the subcutaneous tissues suddenly lose support, and skin looseness may occur, especially when the amount of lipolysis is too much; 4, uneven skin: uneven local lipolysis is the main reason for uneven skin after fiber optic lipolysis, which can be repaired by secondary surgery; 5, infection: if the surgical instruments of fiber optic lipolysis are not thoroughly disinfected, or if the postoperative trauma is not properly cared for, there is also a risk of infection; 6, poor effect 6. Poor results, especially for the abdominal and facial areas with excessive fat accumulation, due to the lack of swelling fluid dissolution, fat dissolution is not enough, coupled with the inability of negative pressure suction and poor results; 7. Local skin damage, such as improper operation may lead to local skin damage.
