Concealer, my one true makeup love! Don't know what I'd do without you. Concealer is a must in my makeup bag, no matter where I go it comes with me. Since not wearing foundation has much nowadays, concealer is a very good way to keep very natural but cover up them imperfections or dark circles. I wear concealer mainly to hide my grey under-eye circles! With my grey bags under my eyes I need more sleep however that is not always the case so I need a very good coverage concealer! *DRUM ROLLLLL PLEASE* "Clarins Concealer Stick" is my perfect concealer.
