You could use a taklon foundation brush to dot it onto your cheeks (make 'the face' if you're not sure quite where the apples are), and then blend with a flocked sponge or a bit of cotton wool.
It's probably not my place, but ladies, please (forgive my OCD in this matter) do not stick thy fingers into cosmetic jars directly. Skin oils, dead skin cells, the odd bit of bacteria - don't mean to gross anybody out, but even if you're the only one using it, it's not a great idea. If you've nothing else on hand, just use a cotton round, or even a bit of cotton wool (you can stick a few balls of it in a plastic bag, won't take up room needed for school supplies). But no fingers in the jars!
I'll get off my soapbox and leave quietly now.
