Yes, try the XFML, you might like it. Don't put too much though. It feels smooth and gentle but it is very strong - so just a bit.
I know that some people prefer it over zz and some prefer zz, I guess it differs from person to person.
Also, Demodex Solutions don't have a refund policy, but they write in the web site that if you don't like or are allergic to some products, they will exchange it. So, the worst that can happen is that if you don't like the XFML you can replace it with zz.
