You may experience mildly pink or red skin, tenderness or discomfort, swelling, tissue firmness or nodules in the treated areas. These are all expected side effects that usually resolve within a few weeks. Tenderness may occur as early as the day of treatment and can last up to two weeks. If needed, use a cold compress and/or acetaminophen to help relieve tenderness. Other less common side effect will be discussed at the time of your consultation.
