I cannot express how much I love this product. This is supposed to be a medium to full coverage foundation, but I have found it to be more of a very smooth and creamy tinted moisturizer. I have noticed a huge difference in my skin since I started using it! This stuff does what it claims and helps to strengthen and repair the skin barrier (mine was horribly suffering from over exfoliation) and my skin isn't as dry as it was before. While it can be worn alone I don't recommend it. You should start with moisturized skin with SPF (this is very important as it doesn't have any) and I also use a primer to correct some discoloration and redness. If you have acne scars, redness, discoloration, active acne, etc, then you must set this with a powder to achieve full coverage. I haven't found one that I like yet so I am thinking about getting the IT Cosmetics Celebration Foundation powder. The reason I want to stick with this brand is because it is one of the only ones that doesn't irritate my sensitive, combination (dry in parts), acne-prone skin. I have not broken out because of it and it feels so natural while wearing it. It is great for winter too when your skin is dry or easily irritated from the cold wind. When I go to work-out like running or cycling I have noticed that it creases around the mouth and starts to come off in areas. However, this isn't a deal breaker for me. I think its important to blend the product very well which leads to a more sheer coverage, but will increase its longevity. I recommend it for mature skin as well. I don't have wrinkles, but this product doesn't settle in creases like around my nose or in the crease below my bottom lip. I see myself using this as long as it is on the market. Love, love, love!
