I have been really impressed with this concealer, it covers my dark circles as well as my Collection Lasting Perfection, but matches my skin tone better. It lasts all day without creasing too. At £7.50 it is a little pricey as with the rest of the No7 range but the £3 off vouchers come round often enough and £4.50 is a bargain for the quality. For anyone who hasn't been colour matched on No7 it really is worth a try!
Have you tried the No7 foundation matching service or the concealers? I'm really loving this combination at the moment.
