How to get rid of dermal spots include drug therapy, surgical therapy, photoelectric therapy, cryotherapy and so on. 1. Drug therapy: For general dermal spots, drugs such as vitamin C can be used to lighten the spots. 2. Surgery: If ordinary drug therapy is not effective, then surgical methods such as skin excision and suture can be given to treat it. Surgery is more traumatic and the boundary of spots is usually irregular, which is not common in clinic. 3. Phototherapy: If the dermal spots are not big in scope, then suitable laser therapy can be used to improve the spots. 4. Cryotherapy: if the dermal spots protrude from the skin surface, then liquid nitrogen freezing can be given to improve the spots. Finally, if dermal spots appear, please consult a doctor in time. The above medicines and treatments should be carried out under the guidance of specialists in regular medical institutions.
