Not my favorite.
Color: Medium Sand
I wanted to like this foundation, but it ended up being too drying on my skin. The finish looks chalky rather than smooth, which makes it hard to get a natural look. Unfortunately, it just didn’t work well for mE.

Azelaic Acid Sunscreen A MUST!!!! BEST sunscreen!!!
Style: Acne/Rosacea Prone Skin
Finally!!!!! I have found a sunscreen that actually helps my skin!! I have tried so so so many! Around 25 different types! From $-$$$$! This one is so great! It is still a sunscreen and feels a bit of a sunscreen at first but once it has set it is amazing! I would absolutely recommend! I have acne prone, dry, sensitive skin and this has not broken me out isn't heavy and hasn't inflamed my skin. It has actually improved my skin. I like the lower list of ingredients as well. I use Retin-a 0.1% (at night) and use a moisturizer AM&PM (person and covey DMl) under this. I would say it isn't a stand alone moisturizer. Would recommend this! And will be buying another one once this one is out! Pros: Liquid/watery consistency Minimal ingredient list Works great with makeup Layers nicely No white cast Easy to remove Nice packaging Good price point Great for acne/acne prone skin Flaky skin approved Not shiny Actually helped my skin Azelaic acid Cons: Slightly like applying sunscreen at first
