    “I love the fact that it has SPF and does not break me out, being that I am prone to breakouts. It has great coverage and lasts day and night. I am in love!”

      Best foundation ever

      I am absolutely in love with this foundation. It really does what it says when they say it improves your skin. I was not happy with my initial color and they changed it out at no charge, ensuring my satisfaction. All the products are great, whether you’re looking for really good light-weight coverage, which this product offers or some of the others that you hardly notice you are wearing but still get a light look. I was alternating between this brand and another one that is also healthy for your skin, and found that Kosas just blends better. And no creasing!!! I highly recommend this to anyone looking to better their skin while looking beautiful!

      LOVE LOVE LOVE

      Just repurchased when i ran out. My daughter recommended this while we were black friday shopping 11/25. My shade was out at sephora but i got a sample and i purchased online directly from KOSAS. I LOVE the soft buttery feel, and the natural feel of it like im not wearing make-up. i usually only wear tinted moisturizer, and this has that type of feel and coverage for me. I have great skin but this just gives a light blend when my skin tone feels a little uneven. I love the more natural ingredients and this is my new favorite foundation.

      Time for a change...for the better

      I ordered this foundation to try something new after YEARS of using the same foundation. Previous foundation was of a similar price point from a very reputable company but as my skin had matured, I found it settled in the fine lines around my eyes and lips, making them even more visible. Not a problem with this foundation. It sets beautifully and wears all day, no matter how I put it to the test. It feels light on my skin but provides the full coverage I like. Just when I thought my liquid foundation days were dwindling like my youth, this foundation brought new life to my daily routine and my skin as well.
