(Question from Lisa in Broadripple, Indiana) Yes, these are potential adverse side effects of laser hair removal. This is why it is important to use a reputable provider and experienced technicians. Most burns are caused from inexperienced technicians, sun or tanning bed exposure two weeks before or after treatments, light sensitive medications and skin care products that contain certain acids. Experiencing hyper pigmentation or hypo pigmentation are temporary side effects that could happen. Communicating honestly with your technician and notifying them of any changes in medication or skin care products will ensure that you have a safe treatment with excellent results.
