Ultherapy is a nonivasive procedure for facial skin lifting, and because there are no injections or surgery the use of ibuprofen or other NSAIDs is ok. After a surgical procedure these types of medications may contribute to bleeding or bruising. There is not usually any significant discomfort after Ulthera so pain meds aren't needed but can be used if necessary for other reasons such as headaches.
I have been doing Ultherapy since 2011 and have done hundreds of patients. My regimen is to give ibuprofen an hour before, immeditely before the procedure and 24-48 hours after the procedure along with Swell-X, a biofavonoid formula for 10-14 days.
