Hi. I've been using Prescriptives Virtual Matte Makeup in Blue/Red Fresh Rose 18 for years. I love it, so I'm gutted that it's gone.
I’ve been searching for an alternative. For anyone else who wears this shade, I can say that the closest match I have found is Clinique's Even Better Makeup SPF15 in 02 Fair.
I've looked at dozens of foundations, and the Clinique one is very close to the Prescriptives Fresh Rose. It may not look quite the same on the back of your hand, but on your face (well, on my face) it's as near as doesn't matter. The only difference is that the Prescriptives foundation is totally matte, whereas the Clinique one has a 'natural, luminous finish'. But, put a bit of loose powder over it and they look the same.
Hope this helps.
