Age spots can be treated by freezing, cauterization and surgical excision, etc. The specific plan should be chosen under the guidance of doctor. 1. Freezing: Liquid nitrogen freezing liquid is applied to the surface of age spots to destroy the tissues through localized low temperature to make them fall off gradually, but this method may cause swelling, irritation, blisters and other discomforts. 2. Cauterization: carbon dioxide laser cauterization or ionization cauterization can be chosen to destroy age spots directly, which may cause pain and pigmentation. 3. Surgical excision: this treatment is more thorough, and the excised tissues can also be sent to the pathology department for examination to exclude malignant tumors. When age spots are obvious, you can actively go to the hospital and follow the doctor’s instructions for reasonable treatment.
