Will Limited Sun Exposure Before Ultherapy Cause Welts and Swelling or is It More Likely Due to Incorrect Depth of Procedure??

I can not comment on your specific treatment or its results as I have not examined you nor am I aware of the exact treatment technique. 

In general, some patients do develop very temporary welts when the newer 1.5mm superficial transducer is used. They go away in as little as one hour and as long as a day. There might be unusual conditions that are not diagnosed in certain patients such as physical urticaria. This is a condition in which hives occur from physical trauma. Some people get pressure urticaria (hives in their skin from prolonged pressure such as tight belts, socks, holding screwdrivers in their palms) or cold urticaria, and others have dermatographism in which slight scratching produce linear welts. Sometimes this is provoked when there is an underlying coexistent unrelated problem such as a dental abscess, bladder infection, bronchitis, etc.

As long as the ultrasound gel is used and there is a good contact of the transducer against the skin, the normal welts should go away quickly.Blistering should not occur but if it does, please don't pick at the blisters or pop them. You must see your doctor immediately if that happens.

You do have an unusual situation and you should see your doctor now.

Perhaps there was a concern with the device and it was recommended to stop and have you return at a later date when the device was checked by the manufacturer. i have not found, in my large experience with Ultherapy that patients are more susceptible to developing welts with recent sun exposure. Welting occurs rarely and usually occurs when the transducer is not kept perpendicular to the skin along 'treatment lines'.Read the Ultherapy ebook provided on the link below. 

Anon: Hope you have recovered uneventfully.  I incorporated the Ultherapy technology into my practice, after there had been a software upgrade in October 2012, so have only had a limited number of patients, however, have not thankfully had anyone have any redness or swelling which lasted longer than an hour after treatment.  Ultherapy is designed to give the practitioner a lot of information about where to deliver the energy as well as whether there is adequate gel coupling or contact between the skin and "head" by producing a consistent image on the screen.  I was taught to confirm the image before delivering the pulse, so it is fairly labor intensive. The only exclusionary factor of which I am aware is the recent use of Accutane, <6months.  Good luck.
