When you say 'use it with' do you mean take a little HQ & RA, mix it into the oil & apply? If that's what you mean, then NOPE. No can do. if you mean applying your HQ in the morning, then your sunblock, then the oil, I'd suggest no: natural oils attract the sun. If you mean using your HQ/RA in the evening, letting your skin absorb it for 2 hrs or so then applying the oil (as a dryness preventative) then YES. that you can do.
