Dear Michelle4444:Congratulations on deciding to have Ultherapy for tightening and lifting your skin and improving skin texture! You did not mention if you are treating lip lines, forehead furrows, jowling, smile lines, eyelid wrinkles, neck or chest lines, abdominal or arm laxity, or trying to lift your brows. No matter what area you treated, taking ibuprofen for one day will not affect your results, although it is best to take Tylenol for pain rather than aspirin or ibuprofen for the next few months.Be patient and you should be happy in three to six months even though you took ibuprofen for a headache!I will be demonstrating Ultherapy and offering free consults, discounts, and a few lines of treatment to anyone who wants to see what the treatment is like on the 25th.All the best, Dr. Clark
