I just exchanged for this for one of the items in my starter kit that was too dark for my skin tone. The exchange was very quick; it took about five days round trip to get my new product. I put on the matte powder underneath my foundation before going to work. I worked for 10 hours through a rather scorching day going between indoors and out. I came home and looked in the mirror, expecting to see an oily mess like I usually would. (My skin is normally very oily.) My skin looked just like it had when I first put my makeup on before work! Even my nose and t-zone were oil free. I highly recommend this for people with oily skin. Despite the fact that it is a "matte" powder, it blends in with your skin a few minutes after putting it on, so it looks natural and not powdery or fake, which makes it perfect for my tastes. It is the first oil absorbing makeup I have tried that absorbs oil all day, lasts through work, and looks natural. It also being one of the Mineral
Hygienics products, I know it will be safe to use with my acne.
