The Laura Mercier secret concealer is one of the most popula concealers and used by the celebrities. It's also been featured in several magazines for example In Style magazine included the product in the Hollywoods secret weapons article. I had a makeup done by a Laura Mercier makeup artist at Saks Fifth Avenue and she used the concealer under my eye. After the makeup I fell in love with Laura Mercier products and use several of them. I have the stick blush, tinted moisturizer, loose powder and the cake eye liner.
