On the whole, RF microneedling is appropriate for all skin tones and types. Since the skin injuries created are so small, there are rarely side effects afterward. RF microneedling can be applied to most areas of skin, including the face, arms, neck, chest, and legs. RF microneedling is not recommended if you have used Accutane recently, plus if you have an active skin infection, herpes simplex, or open wound. Additionally, you might not be a candidate for RF microneedling if you are pregnant, nursing, or getting radiation treatments.
