I use this when I need to touch up my makeup. The case is so simple and cute!!! In the morning, I use MAC foundation, Fix in the summer and Radiance in the fall and winter. Most powders tend to apply strangely if my skin is a little oily or dehydrated, and touching up can make my makeup look messy. However, when I apply this foundation with the brush that came with the tfit powder, it blends in my pores nicely and makes my skin look beautiful. The powder feels soft. I tried applying it on my finished skin in the morning, and it looked even better. Over time, both foundations blend nicely into my skin, moisturizing it rather than mixing with my sebum and making it look messy. It doesn't come with a puff, so I used a brush, but I feel like it applies better with a brush. It's a little yellow, but it's hard to tell when you apply it, so it's fine. If I were to touch up my makeup with a powder foundation brush (a flat brush like Esprique's), I feel like it would look a little messy. If I were just applying powder at first, that brush would probably be better. It's so pretty, I'll be using M.A.C for a while. But I wonder if it has SPF?
