Small glands just below the surface of the skin called sebaceous glands produce a natural oil called sebum. If too much sebum is produced it causes a build up of oil in the hair follicles which creates an ideal environment for bacteria to grow. This can occur all over the body including the face, neck, back and chest. The N-Lite non-surgical laser aims to treat the root cause by targeting the bacteria causing the skin infections. It can be used on all skin types and all affected areas.
