My thoughts on SP Crystal Pink: This MSF is the most glittery one, giving an almost metallic pink finish that on my NW 20 skin looked rather artificial. It reminded me strongly of the Mineralize Sheersheen powder in Lucent, which I use as a highlighter, but Lucent is more subtle. For an all over face application, you need some courage to pull it off during the day-time and/or apply it with an ultra-light hand, in which case it defeats the purpose of CP. I found it to be much more glittery than RQ, which is further emphasized by the metallic sheen. It can certainly be used as a highlighter, but there are probably better, more appropriate, and less expensive highlighters (including other MSF) out there that give you a similar, but not as metallic-dramatic effect. To me, it looks more like a runway finish or what you would see in a high fashion editorial rather than what you would wear on the street (and I am rather open-minded about bright and shiny colors). The metallic part seems to be mostly the outer circle, so if you are just interested in the glittery part, you could only use the inner circle if you pick one that has a relatively large nipple. Again, if you are just using one part of the product, it probably defeats the whole purpose of this MSF. If you apply it lightly, it might help you to achieve a winter-fairytale look if you are very pale (think of the Sugarplum fairy in Nutcracker). I am sure there are certain people who can pull it off and it will look stunning, but it was not to my liking.
