As a primer, I'm skeptical about this product. A 'primer' suggests that it should do something to prepare the surface of your skin to receive foundation in a smoother fashion, and with any luck prolong its longevity. While this isn't a primer to fill the crevices and smooth over, if you have very dry, dull and sallow skin this will work wonders for you on its own, mixed or under foundation to give you a bit of dewy glow. With my youngish, oily skin it works beautifully as an understated highlighter - cheekbones, browbones, bridge of nose, centre of forehead and cupids bow. Despite my shiny skin I think a bit of highlighting adds sculpture and radiance.
What do you think of this Lumi Magique range from L'Oreal? I've put off trying the foundation as I think it would make me an oil slick by midday - thoughts? The concealer pen looks pretty interesting - a possible YSL Touche Eclat dupe?
You can pick up the Lumi Magique Pure Light Primer* for £9.99 and at the moment Boots have a buy 1 get one 1/2 price offer on L'Oreal products.
