High Frequency is a rapid oscillating current (also known as the Tesla Current) that can produce anywhere from 60,000-200,000 hertz of frequency. This rapid current does not produce uncomfortable muscle contractions, but rather a gentle warming sensation on the skin. It is applied to the skin using a glass electrode that is vacuumed sealed with either argon or neon gas. Argon helps to treat acne lesions and neon is great for general and oily skin types, and can aid in deeper product penetration due to it's more localized warming effect. High Frequency also produces ozone, which has an oxygenating effect on the skin. Oxygen is also known for its bactericidal properties, and its ability to reduce inflammation and carry nutrients deep into the dermal layers.
Due to its amazing germicidal abilities, high frequency is an incredibly effective treatment for acne, blackheads, and whiteheads. It also increases circulation which in turn stimulates collagen production, aids in lymphatic drainage and removal of dirt and debris thereby decongesting pores and shrinking them back to their normal size. Additionally, high frequency also aids in sebum (oil) regulation and can be a useful treatment for puffy or dark under-eye circles due to its stimulating abilities.
After a facial, the skin can sometimes "purge", and you can end of with a temporary breakout before your skin gets better. High frequency can help to minimize or even stop this process by destroying the p.acnes bacterium deep within the skin, before it even has a chance to surface. The thermal energy produced by this amazing current, as well as the argon/neon gases and its oxygenating ability, make this an all around amazing treatment for the skin.
