My skin seems to break out with heavy foundations so I need something that's light but also a good product. My friends have recommended MAC foundations, but I'm not really sure if I want to take that big of a hit to the wallet without asking around first. I'm 17 so I still have the typical adolescent woes of the skin, and as I said before, heavy stuff tends to make my face go crazy. I need something that covers it well, but doesn't irritate it and also isn't thick. I hate matte looks and really want to get some good makeup for my senior portraits; I don't want it to LOOK like I'm wearing makeup. Any suggestions?
