A radio frequency cautery procedure is often performed in order to remove warts, skin tags, keloids, lumps, unwanted hair, or any type of damage caused by the sun.


An electrode or probe is used to deliver radio wave energy after topical or local anesthesia. Coagulation necrosis of tissue proteins and carbonization are caused by the generated heat. The raw skin will heal in a few days. There is a possibility of hyperpigmented or hypopigmented residuals (rare) which will fade after few weeks.


  • Since the treatment leaves no scars and the recovery time is short, it is particularly useful for growths and spots on the face.
  • It is common for growths to appear on the arms, chest, neck, and face.

Medical treatments
A radio frequency is passed through soft tissue to cut, coagulate, and remove it. The 2mhz-Megahertz frequency is selected depending on the purpose for the tissue removal. An active electrode is used by the doctor in order to transmit radio waves. The concentrated waves generate steam within the cells, which is then vaporized and divided, eventually causing the cells to vaporize and divide.

Amount of sessions needed:

An RF Cautery will usually require several sessions to remove, except when it is a benign tumour.


  • Bleeding
  • Infection
  • Scaring
  • Pigmentation

A few benefits

  • A minimum temperature requirement
  • No charring resulting in the least amount of tissue damage
  • Cutting is not necessary
  • Least amount of blood loss
  • Painless
  • Shock proof
  • In superficial procedures, or when the skin is at the surface of the body, local anaesthesia is not required
  • Sparkless procedures
  • Precise cutting

Follow-up care after treatment

  • If you notice the wound becoming painful or red, speak to your doctor immediately.
  • The scabs will fall off if you wash gently with a gentle cleanser over a period of 1-2 weeks.
  • Sun exposure should be avoided
  • As soon as the treated area becomes the colour of your actual skin, take proper care of it.
