I love and adore this foundation. I have really sensitive skin and a lot of allergies, and this doesn't cause me to break out! The little brush provided does help apply an even amount of product, but I find better luck using a kabuki brush - it applies it more smoothly, so I have less to touch up. It feels a little weird going on - almost wet (thus the Aqua name?) I used to use the 002 color, but they cut back on the availability, and have switched to the 004 instead. It doesn't quite perfectly match like the other kind did, but it's close enough as long as I don't apply it too heavily. It helps even out my skin tone, and covers small blemishes. It lasts usually around four hours before I have to apply a little touch up. I don't use primer (because of the aforementioned skin problems), so I feel this is pretty good.
