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, it is observed that fiber optic lipolysis may have the following hazards: 1. post-operative hematoma and pain: fiber optic lipolysis needs to dissolve the subcutaneous fat tissue, so hematoma and pain will occur after the 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 laxity: after fiber optic lipolysis, the subcutaneous tissues suddenly lose support, and skin laxity will 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 the postoperative trauma is not properly cared for, there is also a risk of risk of infection.
