Some salons and beauty parlors use high-frequency machines to prevent or help with treatment of facial acne or other skin conditions. The treatment is a form of cosmetic electrotherapy.
High-frequency cosmetic machines may help tightening skin pores, improving oxygen levels and reducing the appearance of wrinkles, pimples, acne and other minor skin conditions. High-frequency waves help tone the skin and increase blood circulation in the area. Trained beauticians mostly use these types of machines in beauty salons, but some smaller portable devices are also available for personal use. If used correctly, high-frequency energy machines are perfectly safe, and the treatment isn't painful.
