Absolutely obsessed, can't recommend enough!

My skin actually looks better and better with every use—blemishes are improved, and I look more moisturized and radiant overall.

    LOVE the sample cards!!

    I always have a hard time picking the right shade of foundation for my skin tone. It is wonderful that I can get samples of the different shades to find the right one before I order the full size.

    It is even more wonderful that I get a site credit (in the amount of the sample purchase) to apply to that full size purchase!

    SO worth it!

    Received the foundation sample card as part of the “try the website” set. I have a very hard time figuring out what shade I am so whenever I saw this product I was 100% all about it. I tried three before I found a good match. I loved the coverage and it lasted all day. I traveled for over 7 hours the day I tried it and my makeup looked great the whole time.

    Best foundation

    Love this foundation 70 years old and I think it makes my skin smoother. Just trying to figure out which shade is best. Several work very well.
