Fulguration is a method that uses which of the following?

Fulguration is a method that employs high frequency to achieve its effects. This technique is often used in dermatological and cosmetic procedures to treat various skin concerns, including the removal of warts, skin tags, and other superficial lesions. The high-frequency electrical current delivers heat to the tissue, which causes tissue destruction through thermolysis, effectively eliminating the targeted skin imperfections.

Using high frequency allows for precise control over the treatment area, minimizing damage to surrounding tissue and promoting faster healing. This method is reminiscent of other high-frequency applications in esthetics that aim to rejuvenate the skin or purify it by targeting bacteria and stimulating circulation.

The other methods listed, such as ultrasound, laser treatment, and LED light therapy, utilize different principles and mechanisms. Ultrasound is typically involved in deeper tissue manipulation and enhancing product penetration; lasers focus on specific wavelengths of light to produce thermal effects; and LED therapy uses different color lights for skin rejuvenation purposes. Each of these methods has its unique benefits and applications, but they do not specifically align with the principles of fulguration.
