  • "this is a super longwear foundation! the coverage is beautiful and is so lightweight. it’s super easy to apply with any brush and leaves a matte finish." in 114 reviews
  • "i received this in a sample size with my sephora order a few days ago and have been testing it out since then. i picked cashew 2n1 because it was the most neutral toned shade, but it showed up a little ghostly on my face so i fixed it with a little extra bronzer. the consistency isn’t too thick or too liquidy, and the finish is more on the matte side which is kind of a surprise to me since most foundations that claim to be matte have a satin, demi matte finish on me. im not complaining though. i didn’t notice it feeling too heavy on my skin, but it did look it over time. throughout the day, my makeup just looked flawless and all my other products blended beautifully over it. this is a pricey one, but if you don’t care i’d day give this a try" in 29 reviews

I absolutely tried this one time and eventually fell in love. It’s pretty heavy and lasted me my 8 hours of work. The coverage is so good I didn’t have to fix my foundation at all. I would definitely recommend to my co workers!

This might be the best foundation and setting powder that I have ever used. I have searched and searched for a product that provides full coverage but doesn't look cakey, evens out my skin tone, and lasts all day in the Florida humidity. This product is it!! I am in love and I don't think I'm ever going to turn back. You hardly need any foundation for full coverage, it sets quickly, and spreads easily. The only downside is the price, but I have to say it is almost worth it. I adore this foundation.

I went to Sephora to purchase this makeup. And apparently it’s yellow toned and I think it would be better if I would come in more colors. Other than that it seems to be really good.

In my eyes, Laura Mercier can do no wrong. From her primers to her illuminators, eyeliners, lip glosses and more... it's rare I encounter a product from her brand that I don't like. However, I was skeptical when first trying out this foundation because I've never really found one from her line that I've loved. Either they've felt too heavy on the skin, weren't long-lasting enough, or I just couldn't find a shade that worked for me. But this? This is amazing. It feels like absolutely nothing on the skin but covers everything. It lasts all day, even without being set with a powder. And I already found two shades (my summer and my normal) that match me perfectly. She killed it with this one!

I really love this foundation. It’s medium to full coverage. I would highly recommend I don’t use so much just because I have been one a natural dewy look. But I would recommend it
