There are some side effects that you might experience, but they tend to be mild and typically clear within a week or two. These can include swelling, itching, bruising, rash and redness. You can minimize these side effects by following the recommended post treatment protocols, which include not applying anything to the skin until the next day, using ice packs, trying not to touch the treated area and avoiding heavy exercise that day. Your doctor will discuss all of the pre and post treatment instructions with you.
