On the whole, this treatment is appropriate for all skin tones and types. Skin injuries created by microneedling are so minor, there are usually no side effects afterward. It can be performed on most skin areas, including the arms, face, neck, chest, thighs, and calves. This procedure isn't recommended if you've been on Accutane in the last few months or if you have herpes simplex, an open wound, or an active skin infection. You may also not qualify for microneedling if you're nursing, pregnant, or receiving radiation therapy.
