i use mine daily.
under the eyes if im looking tired, and above the eyes just under the brow to make my eyes look bigger and brighter
i also put a spot just above the cupids bow of my lips if im wearing lippy to make my lips look a bit bigger (dont know if it works tho!)
i sometimes use benefits 'fake-it' but thats a bit heavy on your eyes (more cakey and can drag the skin) although i do find it hides dark circles better. and touche eclat is lighter for the summer
