When I use this foundation, I never have to apply a concealer. This foundation really covers my dark under eyes and it’s so flawless. It is buildable so if you need more coverage, you can always apply more. What I love about it is it’s never cakey on my face. It feels so lightweight and doesn’t feel like I’m wearing make up. I have a medium skin tone and I chose the #03 Petal. On the photo they show on here, it seems to be very light in color but after it oxidizes on my skin, it is a perfect shade and it evens my skin tone as well which I love. I do apply a little extra under my eyes when I feel like I didn’t get enough sleep but that is perfectly fine with me since I only have to use one product now and not two (foundation & concealer). On the side note, my skin is prone to acne and I’m so amazed that my face doesn’t break out from it. I’ve been using this product for almost two weeks now.
