  • "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

Okay so I work at Sephora and we got this foundation in store recently so I decided to sample it because I've been looking for a new foundation, OMG I usually love my NARS All Day Luminous but this foundation was perfect on my skin! It's a little thicker than the NARS but it still feels very light on the skin and the coverage is great. Needless to say I'll be buying a full size soon!

This is a full coverage product, but it sets in very quickly, so if you haven't blended right away it doesn't. It can kind of give a cakey look since it has a matte finish. If you have large pores like I do, use a good primer first or it's like mini targets on your face. I think once I find a better primer I will like the coverage better, it's a perfect match to my skin tone.

My favorite foundation by bh cosmetics got discontinued, I have been on the hunt for a new one for a while. I have very fair oily skin with large pores and some redness on my nose. This foundation was light enough for me and it covered very well. It didn’t seem to last all day and it slid around a little bit. I returned it. Maybe good for normal skin but not super oily.

Review for: 2W1 Macadamia more...
I finally found my perfect yellow-enough shade match!! This foundation is lightweight yet full coverage. It looks natural on my face and can be built up without looking cakey. It has a satin finish, which means I can run out of the house quickly (vs a matte foundation that may fail my dry cheeks.. or a dewy foundation that makes my forehead shine like a disco ball)

I have very oily skin and it’s hard to find me a foundation that will give me full coverage, hold up to the oil, last all day without separating and looks flawless. This foundation provides all of that! I was so happy when this was recommended to me. This is truly a match made in heaven and as a bonus, it doesn’t clog my pores or break me out!

Ahhh I love this foundation. A little goes a long way and it's definitely building for a girls night out a by more glam. I like that it's lightweight and easy to apply. There are so many color options! I received this complimentary from Influenster and I am so impressed with the product!

Review for: 1N1 Creme more...
This foundation blends smoothly on my skin and stays put all day. Especially when I pair it with the Laura Mercier finishing powder. It does not settle in my pores or crease under my eyes like other foundations tend to. It is defiantly true to color and worth trying. I would almost compare it to the Kat Von D Lock It foundation, but not as heavy on the skin.

This is my new favorite liquid foundation. I'm always on the hunt for a new one that is even better than the last, but this was beyond all my expectations. It looks like skin without being too luminous or too matte. It really does help with my makeup because it is the perfect base on which to place everything else. I would highly recommend this is you have normal skin type.

RAVE! This is a must try product for anyone who likes full coverage and long lasting foundation. The colors are not exactly in order of lightest to darkest so I would go in and try some out! Or order two colors if you are not sure. I was between shell and creme and needed to try both on to decide! The price is moderate and worth the money. I would recommend!

Review for: Buff more...
I saw this foundation reviewed by youtuber Diana Saldana and she tempted me to try this. This first time I applied this with sponge and didn't like it. Second time I applied with fingers and it was flawless. A little goes a long way. I didn't crease and it didn't separate. I purchased this at Sephora. I'd recommend to others. I mixed it with tarte maracuja oil and it was perfect.
