I've used this product many times, but comparing this to other drugstore foundations I always go back to Revlon ColorStay. It has to be the best product I've ever purchased for combination/oily skin, throughout a long school day of 9 hours it always looks just as perfect as when I first applied it, I haven't had the need to wear it for an entire 24 hours but I'm certain it would still look flawless and feel light weight.
Personally I feel this is easiest to apply with a foundation sponge because you have more control and it doesn't leave unwanted streaks that you'd get from a brush, it's very thick & doesn't take long to set so it's best to work quickly. With a build-up coverage, I rarely need to use a concealer for blemishes, I can assure you it will always cover redness of teenage skin without blocking your pores.
The packaging however is horrible, the product comes in a glass 30ml bottle with a plastic screw on lid, you have absolutely no control over how much product you withdraw, within in week of using you'll have to clean the packaging which does waste some product but the actual foundation is far more important than the packaging.
This product is a perfect match to any skin type and skin tone, coming in a range of shades for both combination/oily and normal/dry skin. A must have in ANY make-up bag!
