As with anything else, this product has its pros and cons. Depending on what you're looking for, this could be your holy grail product or a complete waste of your money. I can only speak to my own experience, and my own expectations. Personally, I am extremely pale and extremely olive-toned, apparently. I don't feel like I have an outlandish skin color or anything, but every foundation I have ever bought has been either too dark, too pink, too orange, or an unlovely combination of all three. Makeup companies don't cater to us outliers, as our beautiful sisters (and makeup-wearing brothers) at the opposite end of the spectrum also know. Tired of my head looking like a persimmon perched on top of my neck, I thought it was time to give foundation mixers a try. The first one I bought was LA Girl's yellow pigment mixer. That one comes in a full sized (1 oz) pump bottle, like a foundation except that it is a rich pollen-yellow. As I recall, I bought it from the Ulta website and it cost under $10. That was some help, but of course it couldn't make my foundations lighter, nor did it make them more neutral (or as I think of it, khaki) so I figured I needed a dedicated "olive" green mixer, plus a white. I decided to give Temptu brand a try because they make both colors (LA Girl makes white but not green, or else I would have gone with them again, as you get much more product for you dollar - Temptu's bottles are miniscule in comparison). Unfortunately, Temptu's green was sold out (or discontinued?), so I ended up buying white and blue, thinking I could mix my own green. I did manage to make my own personalized "pale olive" mixer drops, and I guess I'm satisfied with them, but to anyone facing the same problem that I am, and looking for the same solution, let me advise you to just buy all three colors (white, yellow, and blue) from LA girl. You will save money, have much more product to experiment with (and tailor-making your own perfect foundation shade can take a lot of experimenting), and, if coverage is something you look for, you will be much more satisfied with the results. These little Temptu mixer drops are surprisingly sheer. I used up nearly half of my bottle of white trying to lighten a too-dark foundation, pouring it recklessly into the larger bottle, but nothing seemed to be happening. Just trying to lighten a single pump of my favorite foundation required more than five or six drops of white. When I had, I guess, wasted that much of the white, I decided on a different approach. I added one pump of LA Girl's yellow and about six drops of the Temptu blue into what was left of my tiny bottle of Temptu white. This produced an excellent green-white-khaki, exactly what I needed. The trouble is that I have only half of an itty bitty bottle of it, and it requires six drops or more to "correct" a single pump of ordinary foundation. I'll probably run out of the stuff in a couple of weeks. I wish I had just stuck with LA Girl. All that said, I want to be fair to the Temptu brand. They make foundations for use with their proprietary airbrush machine. The sheerness is probably a necessary feature for that to work. I was mixing them with regular drugstore foundations, which they were never formulated for. And I will say, the Temptu drops have such a finely-milled texture that they produce a wonderful "refined" appearance to the skin. They weren't quite ideal as a solution to my issue, but for what they are, I think they're pretty impressive. I won't be buying them again (unless I decide to buy their whole airbrush system - unlikely), but if tiny bottles of highly refined sheerish foundations are what you're looking for, these would probably be perfect. I hope this is helpful for someone out there, since I know I cannot be the only very pale, very neutral skinned person in existence.
