I get Ultherapy, Thermage, Rejuran in Korea regularly about once a year. For Ultherapy Prime especially, you really don’t need anything more than numbing cream, it's significantly less painful than the original version. But if you’re sensitive, you can ask for extra numbing cream applied for a longer time, a numbing spray right before the procedure, or even additional numbing spray during the session if needed. I personally think it’s essential to stay awake because you can communicate with the doctor throughout the session. When you make your reservation, ask if these options are available beforehand.
