As stated this cushion is perfect for hot humid weather! I have super oily face and this keeps my face matte for a good 8 hours before it shows a little dewiness (a healthy looking dewiness which I like) on my face. The level of dewiness that I get from this cushion in 6-8 hours is less than what I usually get from 1-2 hours of other BB/CC's (hot pink skin79 and TonyMoly Aura Live). That's how good this cushion is! Also no need to powder as the formula itself seems to have been mixed with powder. Do bring the compact with you if you're going to be outside in crazy hot and humid weather all day though as I've had a little fading around my nose when I had to be outside in 100^oF weather for 5-7 hours. Other than that no flaws! :D
