"I love this powder! I have very fair skin and use retin-a, which worsens my tendency to burn in the sun. I also tend to break out from nearly every sunscreen on the market. I must also stress that I am a bit obsessed about avoiding sun damage, so I take sunscreen very seriously. This is my second purchase of Colorescience powder, and I honestly can't go without it. Since I started using it, I haven't burned once, nor have I broken out. I apply it over my Make Up Forever foundation and use a kabuki brush from Sephora to give myself that airbrushed look. The powder lasts for hours and never clumps or runs. I'm not a big fan of the packaging, though. The tin is pretty messy. I solved that problem, however, by just pouring the powder into the old colorescience powder orb that I had in my make up bag. This is just a really, really good product and another reason for me to love Dermstore!"
