At Anova Skin Clinic in Floreat, Perth we use Diathermy for Benign Skin Lesions and Growths Removal. Diathermy is a minimally invasive treatment that delivers a high-frequency electromagnetic current through sterile needle probe causing localised thermolysis to destroy benign lesions and growths. Diathermy is derived from the Greek words dia meaning "through" and therme meaning "heat" which literally translates "heating through" – describing precisely how the treatment works. The localised heat coagulates and destroys the targeted tissue, initiating the body's healing response, progressive skin repair and lesion clearance. Diathermy is often less expensive than surgical excision or ablative lasers and can effectively treat a range of benign skin lesions and growths of different origin including skin tags, moles, seborrhoeic keratoses, sebaceous hyperplasias, syringomas, angiomas and superficial capillaries.
Benign Lesion Removal at Anova Skin Clinic in Perth is performed using diathermy – a precise, minimally invasive treatment using a pen-like device that delivers a controlled high-frequency electromagnetic current through a fine sterile probe to the targeted lesions and growths to destroy them.
Diathermy Action for Benign Skin Lesions and Growths:

Depending on the lesion treated, results may include:
⚠️Results are individual and vary depending on the lesion type, size and depth, skin tone and number of treatments required. Your dermal clinician will discuss realistic expectations during your consultation.
⚠️Addition of Omnilux Medical LED – specifically Omnilux Plus (830nm near-infrared light) – when performed prior to or straight after helps to accelerate skin healing and recovery and decrease possibility of scarring.
Typically, the removal of some lesions can be achieved during the first treatment, leaving a micro scab covering the injured skin underneath. The results may be visible immedietely or once the micro scab has fallen off – typically within 1-2 weeks, however the treated area continues to remodel over 2-8 weeks depending on lesion location, size, type and individual healing response.
⚠️Benign lesions and growths have a different cellular composition from surrounding skin – the texture and pigmentation of the treated area may not perfectly match the surrounding skin after removal – particularly in darker Fitzpatrick skin tones where post-treatment pigmentation changes are more common. A thorough consultation is required prior to treatment to discuss expected outcomes for your specific lesion and skin type.
During treatment, a mild to moderate discomfort, stinging, sensitivity, heat or burning sensation at the lesion site is normal.
⚠️Discomfort levels vary between individuals and depend on skin sensitivity, lesion type, size, depth and location. A topical anaesthetic cream can be applied to the area 60 mins prior to treatment to minimise discomfort.
Following treatment, mild redness, heat, swelling, sensitivity, itching, graze-like apperance, scabbing or whitening in the treated area are all normal responses.
Downtime varies depending on the number, size and type of lesions treated and individual healing response.
⚠️Benign lesions and growths have a different cellular composition from surrounding skin – the texture and pigmentation of the treated area sometimes may not perfectly match the surrounding skin after removal.
⚠️Annual skin cancer checks with a medical doctor are strongly recommended.
⚠️Treatment protocol is customised to your lesion type, size, depth and skin tone. Your dermal clinician will recommend the most appropriate plan during consultation.
At Anova Skin Clinic in Floreat Forum, Perth, the cost of diathermy generally ranges from $149-$399 per session taking between 10-50 minutes depending on the treated lesion number and size.
⚠️Serious side effects are rare when treatment is performed by a qualified professional with appropriate technique, client assessment and aftercare.
Side effects beyond the normal healing response are uncommon but may include prolonged redness, pigmentation changes including post-inflammatory pigmentation or hypopigmentation, skin infection and scarring.
