Short-wave diathermy cautery: From £150

We provide Short wave diathermy cautery at our Oxfordshire based skin clinic in Headington. Short wave diathermy is a simple and effective treatment to remove unwanted skin lesions such as benign moles, skin tags and milia. A cautery device is used to conduct electrical heat into the lesion causing an evaporation of water within the cells and destruction of the unwanted skin lesion. This will then scab over for a couple of weeks, before dropping off to reveal a pink healthy skin underneath.

Please Note: We can only treat skin lesions that have been seen recently by your GP, to ensure that this simple procedure is undertaken safely.



We always provide a face to face consultation before any treatment. This ensures you have chosen the right treatment for your skin appearance goals.

We provide a variety of treatments to assist you in reaching your skin appearance goals. From medical grade skin care products to non-surgical face lifts.

Mole And Skin Tag Removal | Frequently asked questions

is there anything i need to do before I have Mole or Skin Tag Removal?

Yes. If you wish for a mole to be removed with short wave diathermy, we request that you see your primary care GP prior to treatment. As part of your general health, you need to ensure that there are no suspicious characteristics to your moles or skin lesions. You may find that your GP will provide this skin health check as part of your primary care or may charge a private care fee for the service. Once your GP has confirmed that it is safe for cosmetic removal, we will book an appointment for you. 

What is Mole or Skin Tag Removal like?

30 minutes prior to treatment, a topical anaesthetic cream will be applied to the area. During treatment you may experience an intense warmth to the area, but is generally described as only mild in discomfort. On occasion, a local anaesthetic may be given for further comfort.

Are there any risks?

As with any treatment that causes a break to the skin barrier, there is a risk of infection. To reduce this risk your skin will be thoroughly cleansed with an alcohol and chlorhexadine solution prior to treatment. Fortunately, infection is rare; the short wave diathermy will cauterise the skin as it treats, killing bacteria and sealing potential routes for infection.

You may find that the treatment area will have a small pink mark following lesion removal, which generally fades over a few months. However, large lesion removal may leave a residual scar that will improve over time.

Are there any post care instructions?

Yes, although these will be discussed in greater detail during your appointment:

-Keep the treated area/s free of water, cosmetics or perfumes for 24 hours

-Avoid touching the treated area/s for 24 hours. It is important to maintain good hand hygiene in case of accidental touching.

-Where lesions have been removed from the body, a small plaster will be applied post treatment. This can be removed after 24 hours.
