With the development of society, people’s demand for beauty is getting higher and finer. The presence of pigmented moles, skin tags, red blood cells, and flat warts affects the aesthetics, and there is now a proven technology in dermatology that can better address this problem. Radiofrequency treatment is a non-invasive technique for cutting and hemagglutination of soft tissues. The operation selects different shapes of the tip to send out radio frequency waves, so that the water molecules in the human target tissue instantly oscillate and vaporize, causing cell rupture and evaporation, to achieve the function of cutting, excision and hemostasis. The advantages of the treatment: 1, no electric current through the body, no risk of electric shock and burns; 2, the operation time is short, generally can be performed under local anesthesia or even no anesthesia; 3, fast cutting speed, good hemostatic effect, fine incision; 4, little postoperative pain, bleeding, infection and scarring chances are small, fast healing. It is mainly used for the treatment of pigmented nevus, spider nevus, flat wart, common wart, seborrheic keratosis, skin redundancy, etc. Unsuitable groups: Patients with pacemakers, scarred bodies, and people with mental abnormalities. Treatment of common complications: 1, wound infection: symptomatic topical antibacterial ointment treatment; 2, scar formation: due to the depth of the lesion site size varies, the scope of surgical damage is different, generally injured and dermal layer will leave scars, some small healing does not affect the appearance; 3, recurrence: surgery due to the naked eye, although the lesion has been eliminated under the naked eye, but there are still residual may lead to recurrence. After radiofrequency surgery: 1, keep the trauma dry, clean; can be used externally anti-inflammatory ointment to prevent infection; 2, to be healed scab can be naturally fall off, do not force peel off, in order to avoid scarring; 3, trauma such as redness, swelling, heat and pain and other discomfort, immediately go to the hospital for medical consultation. Warm tip: Patients should visit the dermatology department of a regular hospital and let an experienced doctor perform the procedure, who will grasp the indications and contraindications. For example, not all pigmented nevi can be treated with radiofrequency. If there are unclear boundaries, ulcers, erosions and itching on the surface, it should be considered that the pigmented nevus has the tendency of malignant transformation, and the treatment is not recommended but surgical removal.
