What is the actual pain like with Ulthera?

Now that I’ve entered middle age, I am worried about my skin sagging significantly. In particular, the nasolabial folds that form as the skin sags have deepened, causing me deep distress every time I look in the mirror. I am considering getting a lifting treatment like Ultherapy because I heard it is recommended for someone my age. I have had Botox and fillers before, but this is my first time getting a lift, and I am concerned because Ultherapy is known to be particularly painful. Would it be bearable if I apply numbing cream, and how does the pain compare to Botox?
