Just wondering if I should be using a "better quality" day cream or night cream? Or does it really make a difference? Which one has the better effect on your skin? ATM, I use No7 uplifting for both day and night but I'm running out of both. I live in Holland so not all the No7 range is available here, and there's not the same choice as the UK, but would be interested to hear what your views are, or any recommendations.
