You can have a topical anesthetic applied prior to your injections. If you think this is the best option for you, be prepared to sit about 30 minutes to allow the anesthetic to work. Ice is another alternative to numb the area. The injections are done with a very fine needle and feel like a pinch. Afterwards, most people get a small amount of swelling at the injection site. Some people get some bruising which can be covered with concealer.
