I just bought L'oreal Studion Secrets face primer (one pink primer in a glass jar). I must say it has been working very well. I have been wearing it for about a week and a half, and so far no breakouts and no problems. I don't have to blot my face at all throughout the day. No caking, pooling, or creasing around the nose. I am wearing MAC Studio Fix Fluid in NC37 and NC40 (I mix equal parts), with MAC mineralized skinfinish natural in medium deep on top. I get flawless finish that lasts all day.
The primer is one the dry side, and scooping it out of the jar can be a little troublesome, but the effects are great. A little has gone a long way for me. It dries to an invisible powdery finish, and truly mattifies the face. If you have dry skin, this primer might dry you out more. However, this is great for oily to combo skin.
