The formula is too runny for my liking and the coverage isn't great. When I tried to layer it for a little more coverage, my face I was a cakey mess. The staying power isn't great either and didn't last me all day and when I wiped it off at night there is barely anything to wipe off. I was also very oily halfway through the day especially on my forehead. I am not sure why but I don't find that Stay Fabulous is a great base for blush and bronzer....every product I put on my cheeks (even pink blush) looks orange! And the worst thing about this product...oxidizing! It looks ok when I first apply it but just give it less than an hour and my face looks orange even with no bronzer. I pump this on my hand when applying and sometimes I forget to wipe it off leaving my hand in an orange mess too! I know this doesn't happen to everyone and a recommended fix is to get a lighter shade but I am already the lightest shade there is so I can't purchase anything lighter. The 3 in 1 doesn't really win me over either - I find better results using a separate primer (I don't mind the extra step) and I don't find the coverage good enough for concealer. I always use a concealer for blemishes and dark under eye circles so I'm not really saving any steps by using this foundation.
There are a few good things - it does blend pretty well with fingers, sponge and flat top brush. Another great thing is the bottle with the pump - makes application a breeze and it keeps me from wasting the product ). Its pretty cheap at under $10 CAN per bottle!
