I apply this with a Real Techniques sponge (aka beauty blender equivalent), and it melds into my skin with no issues. I set it with powder but not the recommended CT powder, because current beauty bank account is tapped out (and the want list is loooooong).
When I remember to prime first, I get approximately 4-5 hours of wear before t-zone maintenance is required.. if I don't 2-3. Regardless if I prime or don't there is one drawback to this foundation, it gathers under my glasses. I tend to have this problem with other foundations, but the gathering is minimal; with magic foundation it's obviously visible... I'm not a fan.
Final verdict not magic, but very nice (if you don't wear glasses). I'm not going to re-purchase... too many new releases to stick with an average product.
