I have a few blemishes and freckles on my face, and a small scar and kept looking for a concealer in my shade.  Could never find one until now.  The MAC concealer is the best concealer.  It  matches with my skin and covers all the problem areas up perfectly.  So glad I finally found a product that works.  When used with the MAC foundation and the powder, it provides flawless coverage.  There's a reason why it's a bit pricey...you pay for quality.
