Your skin will be treated with a local anaesthetic before the procedure, so don't take anything for pain ahead of time.

If you are having something done to the eye area and wear contact lenses, be sure to bring your glasses to wear home. You will need to avoid using your contacts for a few days.

If you are having something done to the lip area and have a history of cold sores or fever blisters, you will want to get a prescription for an antiviral treatment for it. Begin taking the medication several days before the procedure and you will be done with the doses several days afterwards. 

Consult with your practitioner beforehand, and he or she will give you any other advice you need. You may also receive a kit for aftercare to take home with you.
