Short wave diathermy is a safe, precise treatment commonly used to reduce or remove visible facial thread veins. Thread veins—also known as spider veins or broken capillaries—are tiny dilated blood vessels that appear close to the surface of the skin, often around the nose, cheeks, or chin. They can develop due to genetics, sun exposure, ageing, rosacea, temperature changes, or skin trauma. Short wave diathermy works by delivering a controlled, high-frequency electrical current through a very fine probe placed just above the skin. The heat generated coagulates the tiny blood vessel, causing it to collapse and gradually be reabsorbed by the body, which reduces or removes its visible appearance.

​

One of the key benefits of short wave diathermy for facial thread veins is its precision. Because the probe targets only the affected vessel, the surrounding skin remains largely unaffected. The treatment is quick, minimally invasive, and usually requires little to no downtime. Many patients notice an immediate improvement, although some veins may require more than one session depending on their size or number. Compared with some other vascular treatments, short wave diathermy can be particularly effective for very small superficial vessels that are difficult to treat with broader light-based technologies.
