How is electrocautery used to treat acne?

Dr. Doris Day, MD
Electrocautery is the use of an electric current that is converted into heat and passed through a fine tip. It can be useful in a limited number of circumstances in the treatment of acne and is not often used. The heat applied directly to the acne lesion exfoliates the skin and kills the bacteria. It is also sometimes used to open whiteheads so the contents can then be extracted to clear the lesion. There is a risk of scarring from this treatment, which is one reason it is not considered a main treatment for acne.
