You may or may not know, but I tend not to finish products, and I tend not to repurchase. However, shock horror, I have gone and done both. Max Factor have struck gold with their primer - so much so that I ran out, went without it for 3 days and after wearing a primer-less face of make up, ran out to get it. That is how good it is. The effect it has on bare skin is wonderful, the effect is has under a freshly-made-up face is beautiful, and the longevity it has during a working day is the icing on the cake!
I wholeheartedly recommend this for all skin types, and can vouch for how good it works on my very oily skin (currently on offer at Superdrug, wink wink!).
