Becca shimmering skin perfector - I have been a huge fan of this wonder product for a very long time.  I have just purchased the new shade "Moonstone" and used to have "Opal."  As my skin is naturally fair I personally prefer to add warmth to my skin and I find that Opal is actually better for this, Moonstone is infact a mixture of Pearl and Opal.  I still love this product and love the packaging too, which comes with a great little pump which dispenses a small amount of product in your hand, which is all you need.  This product smells great too and not only does it give a lovely pearlised, soft glow it has the added benefit of having a SPF 25. You can mix with your normal foundation if you wish or you can just add to the areas of your face which you want a bit of a sheen/highlight, which is very youthful and flattering, creating a lovely glow using light reflecting particles.  I purchased my product from www.gorgeousshop.co.uk and was priced £26.40 for 50 ml.  I will continue to use this product!
