Diathermy is a safe and effective cosmetic treatment used to treat skin problems such as skin tags, spider veins, dilated and broken capillaries, red spots, milia, and sebaceous hyperplasia.
Diathermy involves the use of a high-frequency electrical current to produce intense heat to a specified treatment area. This heat is passed through a probe the size of an eyelash to destroy unhealthy or unwanted tissue such as skin tags and can be used to clot blood, which effectively reduces the appearance of broken capillaries. The treatment is precise, and only the targeted tissue is affected. Therefore, minimising the risk of scarring or post-inflammatory pigmentation.

What can Diathermy treat? 

  • Broken capillaries
  • Cherry angiomas
  • Milia - hard white deposits under the skin
  • Skin tags
  • Sebaceous hyperplasia
  • Warts

Is Diathermy painful? 

The discomfort of the procedure depends on the treatment area and the type of lesion treated. The treatment process is relatively quick and is customised to meet your individual needs. Raised lesions such as skin tags may feel a slight stinging sensation. In contrast, flat lesions such as broken capillaries or sensitive areas around the nostrils can feel warm and slightly uncomfortable.  

However, most people can tolerate the discomfort reasonably well, and in cases of severe sensitivity, we recommend you apply a topical numbing cream before your treatment.

What to expect post-treatment

Following a diathermy treatment, most lesions will immediately appear white or grey, with the surrounding skin appearing pink. In the next few days after treatment, lesions can darken or appear to become dry or scab-like. This skin should not be picked, scrubbed, or irritated. Following the aftercare instructions will ensure the treated area will heal and clear blemishes within 7 - 10 days.

How many treatments will I need? 

Diathermy will successfully treat most lesions within 1 to 2 treatments.
