Depending on the depth of the mole, you may decide to apply anesthetic or inject anesthetic before spotting the mole, which usually reduces the pain. If the mole is shallow, laser treatment can be used. Before the laser treatment, the topical application of anesthetic for 30 to 40 minutes can effectively relieve the pain. And shallow moles will not leave scars after laser treatment. If the mole is deeper, treatment such as freezing or surgical excision is needed. In this case, the anesthetic can not reach the deeper level, and the method of local injection of anesthetic is needed. Mild pain may be felt during the injection, but no pain will be felt after the anesthetic is applied. Whether or not to apply anesthetic before mole spotting needs to be combined with the characteristics of the disease, personal wishes to make an accurate judgment, it is recommended to decide under the guidance of a doctor.
