This primer is amazing! I bought it on a whim after seeing Mallory1712 on YouTube recommend it. It keeps my liquid foundation from sliding around & clinging to dry spots on my combination skin. I have also been struggling with some acne and bumps on my cheeks/chin that are almost gone since I've started wearing this. I have extremely sensitive/reactive skin and I had not reaction from this primer. This product is unscented, so it does have an odd smell when applying it but it evaporates as it dries. I have tried primers from Makeup Forever, Hourglass, and Trish McEvoy, but this is my new holy grail primer. I'm definitely getting the bb creme next.
