What is Fine Wire Diathermy?
Fine wire diathermy is often used in the treatment of dilated blood vessels on the face and any fine vessels on the upper limbs or trunk. It also has a major role in the treatment of minor skin blemishes such as small skin tags, milia, syringomas, seborrhoeic warts and sunspots. It is also used effectively as part of epilation in the treatment for removal of unwanted hair.
A small electric charge is passed down a hair-like needle into an unwanted spot. This causes the spot to shrivel and disappear in the following few days or weeks, depending on the body part treated and the amount of current used.
The healing process
After the procedure a scab forms after an initial sore. Usually this wound is inconsequential, however, if a large area has been treated, then the sore may be more significant and require a night-time topical antibiotic or antiseptic ointment for seven to ten days.
It is important to protect this treated area from the sun whilst the area is healing, as it may preferentially tan. Therefore sunscreen is recommended and makeup is usually permissible after the procedure.
Scarring and other side effects are very unusual.
