Facial Ultrasonic Skin

Have you ever had an ultrasonic facial?
Why? What skin condition(s) did you have? Did it help? How much did you pay? Was it worth it? What did you like / dislike about it? Have you or would you have it done again?
I had never heard of this treatment until recently, when it was recommended to me for my “old age acne” (rosacea). My skin is extremely sensitive so I’m a bit wary. Thanks for sharing. 10 pts to the most complete and objective answer.
