Short-Wave Diathermy for Effective Blemish Removal

Short-wave diathermy is a safe and effective treatment for skin blemish removal. It uses heat from a fine needle to cauterise and remove unwanted skin lesions. Achieve clearer, smoother skin with short-wave diathermy, a trusted solution for various skin blemishes.

What is Shortwave Diathermy for Skin Blemish Removal?

Shortwave diathermy, or electrodessication, is a minimally invasive cosmetic procedure for removing various benign skin lesions. It uses high-frequency electrical currents delivered through a fine probe to generate heat within the targeted tissue. This localised heat causes coagulation and destruction of the unwanted lesion.

How Does Shortwave Diathermy Work?

The mechanism of shortwave diathermy involves the following:

  1. Heat Generation: The high-frequency electrical current passes through the probe, generating heat within the targeted tissue due to its resistance.

  2. Tissue Coagulation: The generated heat causes the cellular proteins within the lesion to denature and coagulate, effectively destroying the tissue.

  3. Desiccation: The heat also vaporises the water content within the lesion, leading to its desiccation (drying out).

  4. Wound Healing: The destroyed tissue forms a scab that eventually falls off, revealing new, healthy skin underneath.

Clinical Evidence and Safety

Shortwave diathermy is a well-established procedure with a long history of safe and effective use for skin lesion removal. Clinical studies have demonstrated its efficacy in treating various types of benign lesions, including:

  • Skin tags: Small, benign growths that commonly occur on the neck, armpits, and groin area.
  • Seborrhoeic keratoses: Non-cancerous growths that often appear as waxy, brown bumps on the skin.
  • Warts: Rough, raised bumps caused by the human papillomavirus (HPV).
  • Milia: Small, white bumps that occur when dead skin cells become trapped under the skin’s surface.
  • Cherry angiomas: Small, bright red bumps that occur due to the proliferation of blood vessels.
  • Telangiectasias: Dilated or broken blood vessels that appear as fine lines or spider veins on the skin.

  • Precise and Targeted Treatment

    Shortwave diathermy allows for precise targeting of specific lesions, minimising damage to surrounding healthy tissue.

  • Minimally Invasive

    The procedure is minimally invasive, requiring only a small probe to be inserted into the targeted lesion. This results in minimal scarring and faster healing compared to surgical excision.

  • Versatile

    Shortwave diathermy can be used to treat a wide range of benign skin lesions, including skin tags, seborrhoeic keratoses, warts, milia, cherry angiomas, and telangiectasias.

  • Quick and Convenient

    The procedure is typically quick, with most lesions being treated within a few minutes. It can often be performed in a doctor's office without the need for anesthesia.

  • Cost-Effective

    Shortwave diathermy is a cost-effective option for skin lesion removal, often being less expensive than surgical excision or laser treatments.

Steps in a Shortwave Diathermy Treatment for Skin Blemish Removal

An outline of what to expect during your treatment

  • Consultation and Assessment

    We will examine the skin lesion, discuss your medical history, and determine if shortwave diathermy is suitable for your specific case.

  • Preparation

    We will clean and disinfect the treatment area. A topical anaesthetic may be applied to numb the area, although this is not always necessary for smaller lesions.

  • Procedure

    We will use a fine probe to deliver the shortwave diathermy current to the lesion. This may cause a slight tingling or burning sensation, but it is usually well-tolerated. The lesion will typically turn white or grey as it is being treated.

  • Post-Treatment Care

    We will apply a topical antibiotic or ointment to the treated area and provide instructions for aftercare. This may include keeping the area clean and dry, avoiding sun exposure, and using any prescribed medications.

  • Healing and Follow-Up

    The treated lesion will form a scab, which will naturally fall off within a few days to a few weeks. We may schedule a follow-up appointment to assess the healing process and ensure optimal results.
