As with all types of polythene UHMWPE ski bases are degraded by UV radiation so I would go easy with the UV exposure.
This product was developed over a very short period of time, so there would have been no time to test the long term effects on the base material.
This is the patent for Juice, a different product. Patent applications are not published until 18 months after filing

I’m pretty surprised that they haven’t published the results of any of the glide tests they must surely have carried out. Using two strong magnets , an Android smartphone and this app
http://www.skiira.com/products-services it would be easy to carry out some basic glide tests.
