What is Shortwave diathermy?


Shortwave diathermy is the controlled application of electrical current to cause the destruction of cells by heat. It a safe and effective treatment for a number of skin blemishes, such as skin tags and age-related warts.


The diathermy we use


The shortwave diathermy machine we use in our clinic is manufactured by Sterex. This company is a world leader in making thermolysis and electrolysis machines and are based in the USA.


The procedure


The Sterex system uses a hair-fine needle to target the area of concern. During the treatment, it is usual to feel a sharp, hot sensation, especially if the blemish is adjacent to the nose, eyes and lips.


Treatments can take from 5–30 minutes depending on the size of the blemish being treated.


Pedunculated lesions such as skin tags can take the longest to treat. Small visible surface blood vessels, such as telangiectasia, require no more than a minimal application.



After effects


It is normal to experience some redness and sensitivity in the area treated. This usually resolves within 24 hours. Some scabbing may occur.
