Inform your doctor/nurse if you tend to get cold sores.
Make sure you have freshly washed pillowcases (not your best, as they will get ointment on them) and towels for use after the procedure.
Avoid aspirin for 10 days, and ibuprofen (advil, motrin, aleve) for 5 days prior to the procedure.
Vigorously avoid sun exposure for the 2 weeks prior to the procedure. Plan on sun protection including sun avoidance, hat, and sunscreen for 4 weeks post-procedure.
Come to the office with a clean face without makeup and no hair spray or hair gel in your hair.
