What is diathermy used for in skin treatments?

Moisturizing dry skin
Treating telangiectasia
Exfoliating dead skin
Reducing fine lines

The correct answer is: Treating telangiectasia

Diathermy is a therapeutic technique that utilizes high-frequency electrical currents to generate heat within the tissue. In skin treatments, it is particularly effective for treating telangiectasia, which are small, dilated blood vessels that can cause redness and visible skin imperfections. The heat produced by diathermy helps coagulate the blood within these vessels, leading to their closure and subsequent fading from the skin's surface. This method is minimally invasive and specifically targets the vascular issues without significantly affecting the surrounding tissues. Therefore, its application in treating telangiectasia is both targeted and efficient, making it a preferred choice in specialized skin treatments. While reducing fine lines may occur as a secondary benefit due to improved skin tone and texture, the primary and most popular use of diathermy is focused specifically on addressing vascular concerns like telangiectasia.
