Dermaroller treatment is appropriate for atrophic scars, i.e. scars that have a hollow type appearance. Such scars cast shadows and make a person look awful contingent on the lighting. For hypertrophic scars, i.e. scars that have an upraised appearance, there are other methods such as steroid ointments or injections and silicone gels. Dermaroller treatment works best for shallow rolling type marks.
