Radiofrequency skin tightening and wrinkle reduction refers to the use of radiofrequency technology to contract collagen and stimulate new collagen synthesis, including immediate collagen contraction and subsequent collagen proliferation effects. However, there are certain risks associated with radiofrequency skin tightening surgery, including the following: 1, erythema, edema and blisters: in some patients, due to excessive treatment energy or negative pressure attraction, the erythema will last for a few days, and can generally subside completely. In severe cases, obvious blisters may appear, and if there is no reasonable care, secondary infection may occur, resulting in hyperpigmentation or scar formation; 2. Purpura: generally lower the negative pressure value as well as the same part of the body is not repeatedly attracted, which can avoid the occurrence of purpura; 3. Pruritus: during the treatment period or after the treatment, itchy, numbness, or painful sensation will occur in a very small number of cases; 4. Contact and irritant dermatitis: mostly due to the patient’s contact with the coupling medium, caused by allergic reaction; 5, burning or burns: the treatment will cause local burning or burns, usually within 10 days can disappear, sometimes forming scabs; 6, skin atrophy: such as not correctly deal with skin damage, the use of higher radiofrequency energy, easy to cause localized depression in the skin, resulting in gradual atrophy of the skin; 7, sensory and motor nerve damage. To summarize, patients should choose regular plastic surgery institutions for medical treatment, which can effectively prevent complications.
