I've only used one product, but I've heard many good things about the skincare line, and mixed, but generally positive things about the makeup. What I've been using lately is their Intelligent Balance Mousse Foundation.
I've NEVER gotten more compliments on my skin. My mother (one of the most critical of my makeup) commented yesterday how near-perfect my skin looked, and that if she didn't know I was wearing it, that she probably wouldn't have been able to tell it was on. I start with a silicone primer (Monistat Anti-Chafing Gel), dot this all over my face, and blend with the Philosophy Supernatural Airbrush. It has a thick, silicone-based texture, and comes in a lovely, Chanel-esque pot. It sets to a natural matte finish, but I still top it with a bit of powder to prevent the oilies by mid-day (mind you though, my skin is excessively oily). Doesn't set into lines, doesn't crease around my eyes, never oxidizes, completely covers pores and blemishes (no need for a concealer). It's VERY easy to touch up (you know how some foundations, especially liquid just rub off when you try to touch up where it may have rubbed off? Not so with this. Simply stipple with your finger around the area to readjust mild coverage, or stipple a bit more on top for a flawless reapplication). Provides a completely airbrushed finish, even up close. My only gripe with it is how easily it transfers after the oils in my skin have emerged. Fortunately, although it looks like a lot may have come off, your face will look exactly the same as long as you're not rubbing it. As well, a bit more powder can fix this temporarily. I've also found that this stuff DOES not stain clothes if you apply a stain remover before washing. Just my experience! MY HG foundation, for now.
