I had full facial Ultherapy 3 days ago and still have tiny red itchy bumps all over my forehead. Is this normal?

It sounds like you could've had a reaction to something put on your skin prior to the treatment, during the treatment or afterwards.  Some clinic's use a topical numbing cream before the treatment, even though it hasn't been shown to help.  The ultrasound gel used during treatment shouldn't cause a reaction.  If the provider put a sunscreen or other type of facial lotion on after the treatment, that could've caused the reaction as well.  Using over the counter Hydrocortisone cream can help calm it down, but like another physician said, only use this for a day or two as steroid creams can thin the skin. 

Its not common to have a skin reaction to the ultherapy. I suggest you speak to your physician for a formal evaluation.  Sounds harmless though and can be treated easily.  Best, Dr. Emer.

There are 2 possibilities for this. The more likely is that you are having a reaction to the gel that was used with the Ultherapy. Some hydrocortisone cream should calm that down, but please do not use it for a prolonged period of time. The other possibility is that the red welts were created if the orange (1.5mm) transducer was used and did not have good contact with the skin. This is common as the transducer is flat and your forehead is convex. Not much to do about the welts as they should go away. Talk to your clinician if blisters begin to develop.
