Microneedling causes collagen regeneration and the technique has been around for almost 20 years. It restarts the inflammatory process involved in healing and stimulates repair and regeneration with new healthy tissue via collagen regeneration. Although the process causes some bleeding, it is not enough to need a dressing post treatment nor does it damage the top layer of skin. Treatment is usually on smaller areas (rather than larger areas) with a numbing cream applied to the area prior to treatment to prevent pain and special creams given to be used in the initial days following treatment. For best results, a course of treatment may be needed. For example, 4-6 treatments which can be done at 4-6 week intervals.
