The application of high frequency current to the skin also promotes a natural cleansing and antibacterial action that helps treat existing acne and prevents the onset of new acne. Clients experiencing cystic acne will benefit greatly from the deep penetrating germicidal action of high frequency. The skin is left feeling instantly energized, rosy, firm, refreshed and noticeably softer - even after just one treatment. The enriched oxygen molecules produced by high frequency machines are safe and have been proven to be effective in helping to heal and restore the skin's health. High frequency is used to treat a range of concerns from skin lesions, acne, waxing procedures and cold sores to fine lines, sagging skin and puffy eyes. Common areas of treatment include the face, neck and scalp but high frequency can be used on the entire body including the back.
