Diathermy skin treatment is the use of high-frequency electric current to produce heat. This is a quick process where we insert a ﬁne needle into the capillary,which will release a current that will produce heat. This heat will then seal and drain the blood that causes the broken capillaries to appear.
Some skin will develop very tiny scabs after the diathermy skin treatment. This is to enable the skin to heal and you must follow the aftercare instructions as advised by your therapist to ensure correct skin healing.
