"I had never tried face primer before, but having read an article on it was all set to buy the one recommended in the article. A high street brand(EL) whose make-up I've used and with a good reputation. HOWEVER- as a QVC customer too, my friend suggested I try a QVC brand, since I would have the 30 day guarantee. Since YBF was being aired, I decided to try it. Well I didn't return it and have been very pleased with the results, both under liquid and mineral foundation. As I was getting low I did actually buy another well known high street brand (HR), which thankfully I got at a very reduced rate - it wasn't a patch on YBF!! Think I'll stick with the old adage - if it ain't broken, don't fix it. Will be sticking with this in future and have a spare on standby."
