I used to use this consistently a few years ago as it's affordable and does a pretty good job. Nowdays I only purchase this when I've run out of my Napoleon foundation and can't make a trip to Auckland to get any more.
Revlon colourstay has a good coverage, esp if you suffer from red veiny cheeks as I do and is very easy to apply, with either fingers, a sponge or a brush. They have a good colour range too.
The main reason I stopped using daily was I found it was rubbing off during the day around my chin and tip of my nose and I just don't have the time for touch ups during the day.
It's a good all rounder foundation, esp for those just starting out. I like that it has a fairly matte finish, as I'm not into the dewy look at all.
I found this foundation to be similar to the MAC Studio Fix Foundation Fluid. The finish is always really nice although it can be quite hard to work with as it dries quite quickly but it can also be mixed with other foundations to get really good coverage. I always love the way my skin looks after using this, it’s a classic foundation that I always have a bottle of :)
