A safe and effective electrosurgical technique for removing common skin lesions with minimal downtime.
Benign skin lesions such as milia, sebaceous hyperplasia, skin tags, and seborrhoeic keratoses can be persistent and difficult to treat with skincare alone. Fine Wire Diathermy is a targeted electrosurgical procedure that delivers high-frequency electrical energy to precisely heat and remove unwanted lesions, leaving surrounding skin unaffected. This minimally invasive treatment is quick, effective, and requires little to no downtime, making it a preferred choice for those wanting to safely and efficiently improve their skin’s appearance.
