Your injector will give you their specific post-treatment routine. In general you must keep the area clean and dry for 12 hours. There should be no manipulation of the treated area (like facials). You can expect redness, and swelling to be present to some degree when leaving the office. If bruising develops it may last from 24 hours to a week depending on how you heal. You may wish to purchase a supplement called Arnica Montana with bromelin to help limit bruising. If bruising does develop you may wish to gently apply ice to the area. Each injector has their own follow up schedule, make sure you ask them. Be sure you notify the injector of any prolonged swelling, redness, oozing, pain or fever.
