Diathermy to treat minor skin lesions

Diathermy at Karen Bowen Dermal Therapist is a process in which commonly occurring but harmless minor skin lesions, such as those described below, are removed.

Telangiectasias – Small, dilated blood vessels (red veins) near the surface of the skin on the face.
Skin tags – Small, generally skin-coloured growths that may have a narrow stalk and can be irritated by friction from clothing, etc.
Cherry angiomas (red spots) – Often arising in middle age, they consist of clusters of tiny capillaries that form a small, round dome on the skin’s surface.
Sebaceous hyperplasia – Skin-coloured to yellow-white elevations on the skin caused by enlargement of the oil glands (generally found on the forehead).
Milia – Keratin-filled white cysts that sit just under the epidermis (usually found around the nose and eyes).
Xanthelasmas – These growths, mostly found in people of Asian origin and those from the Mediterranean, consist of sharply demarcated, yellowish collections of cholesterol beneath the skin; although neither harmful nor painful, they can be quite disfiguring.

During diathermy, a fine probe is used to cauterize (burn) the lesion requiring removal. A mild, stinging sensation may accompany this process, and if necessary an anaesthetic cream can be applied 30 minutes beforehand.

Afterwards, the treated area will crust over for as long as a week while healing takes place. Generally, removal of the lesion is permanent. That said, diathermy does not prevent further lesions from developing, particularly in sun-damaged skin. In such cases, maintenance treatments, combined with IPL, may be required.
