Exilis Ultra to "dorsal" hands: They seem to look better a week after one treatment.

Initially you get tightening and swelling because of the heat that was placed in the tissue.  This will eventually dissipate. The final results will be seen 3-6 months after your final treatment when the tissue has had a chance to remodel. 

I have used the Exillis elite since its inception in 2011. I find on thin tissue such as the neck and hand the results are very good and more reliable than other areas. All of the non invasive modalities have about a 30% failure rate with little or no changes.Early changes are often for fluid changes in the cell and the genuine collagen stimulation effect appears in about 3 months but hey maybe you responded super well and that's great.
