Patients should discontinue the use of any harsh treatment products they use on their hands for up to two weeks prior to undergoing the procedure. One week before their appointment date, patients will be advised not to drink alcohol or take certain medications like ibuprofen, aspirin, and certain vitamins or herbal supplements, which will help decrease post-treatment bruising. Those prescribed high blood pressure medications should speak with their doctor about stopping or decreasing their dose for a week prior to their scheduled treatment.
