The safest, scar-free way to remove moles & perform electrolysis for certain types of hair removal

Skin Therapy

Diathermy is the safest, scar-free way to remove moles, milia (the white hardened bumps, often around the eyes and cheeks that are difficult to extract), skin tags, and also perform electrolysis on hair types that aren't suited to regular laser hair removal.

Diathermy is a bloodless procedure used primarily for cosmetic treatment of the face, neck, shoulder, chest and back. These are the areas of the body which get exposed to the harmful effects of the sun and the environment and more often develop skin problems.

How it Works

Diathermy involves the use of a high energy current to produce intense heat which destroys the lesion. The area to be treated is sometimes numbed with a local anaesthetic and then a fine hair-thin needle is introduced in the lesion to pass the current. The heat produced destroys the tissue of the lesion and the lesion disappears instantaneously. After the treatment mild swelling and redness may result and this will resolve in a few hours. The superficial sore is left open and allowed to heal on its own and form a scab.

Skin lesion removal

Skin tags, milia, sebaceous hyperplasia and other surface irregularities are harmless, but to some people may be unsightly. They can be quickly yet effectively removed with Diathermy. This method cauterizes and coagulates the lesions through thermolysis, using a fine probe to cauterize benign skin lesions. A fine crusting is then developed over the next few days after treatment which will heal within a week or so. Permanent removal is generally achieved, however it is not a preventative treatment for the development of new skin lesions.


Our clients are always so pleased to learn that there IS a way to remove any unwanted moles, whether they be colourless, brown-pigmented or red (also known as cherry angiomas). Commonly thought to be only suitable for removal with a nasty scar or pigmentation marks left behind, we can remove the unwanted lesion without disrupting the normal skin around and beneath it, with precise and skilled diathermy treatments.

Common Questions

What is the expected downtime with this treatment?

Immediately after diathermy treatment the areas treated can feel warm and sometimes cause itching. This lasts between 30 minutes and two hours, and is a normal part of the procedure. Depending on the type of lesion treated, small scabs can appear however are usually gone within 3-7 days post treatment. Your clinicians will apply soothing gels to the area as well as provide aftercare instructions and products.

Will the diathermy treatment feel uncomfortable?

Clients report the treatment feeling ‘hot’ with a small prick sensation, but not unbearable, and it is performed in very little time. Numbing cream or other forms of topical anaesthetic aren’t generally required, but if need be our clinicians can apply ice to the area.

How many sessions are required?

Depending on the size and type of lesion, 1-4 sessions will completely remove or significantly reduce the size of the skin lesion. Usually, the smaller the treatment area, the less sessions are needed.
