Just wanted to recommend. I was given some for my birthday and I LOVE it. Normally I use Laura Mercier, (which is nearly £40) but actually prefer this. I'm very pale and the Stila light exactly matches my skin - and gives a nice smoothing effect so you look just a bit more polished but not 'makeupy'. Perfect for summer and six hours later I'm not too shiny. I don't know why it's so much cheaper. I was told the LM one is expensive because it has a high concentration of pigment but although the Stila one 'feels' a bit thicker, it gives better coverage without feeling thick on the skin.
I'm in love with this now and will keep using it.
