When I looked at Cover, I was thinking of the cover ups. Makeup that conceals flaws. Concealers.
There are quite a number of excellent make up cover ups here Check out the affordable ones from Almay and the Derma E cover, or the really wonderful demalogica cover up concealers.
Scars could definitely use Scar Fx cover ointments while those who prefer natural cosmetics would love Burts Bees concealers which are natural, wonderful and really cheap.
Other types of covers slipped in as well. Jack Covers and Discover magazine and makeup with lids (covers) Doh. If you look past those slip ups, you will find some excellent covers, or concealers at excellent prices.
