As i posted a few weeks ago i recently purchased the YSL false lash effect mascara in intense black. It was a bit of a random splurge but with the fab offers on Buyapower i couldn't resist. I got mine for £17 instead of the normal £23.
So how is it?
One word: FAB.
Before: Only eye liner, no mascara
After: with mascara

I personally think that the pictures speak for themselves!!! My lashes were miles fuller and i think do have that 'faux' look about them without the mess of glue!!!
The boots website describes it as "An intense look in a single stroke with our must-have industry leading mascara. Yves Saint Laurent Volume Effet Faux Cils Luxurious Mascara's secret: the triple-film complex. A coating film for intensity, a conditioning film for curve, a fixing film for long-lasting effectiveness. Even the brush applicator combines nylon fibers of varying diameters for volume enhancement as never before."
I love it!!! No clumping and no flaking even after wearing it all day.
Its amazeeeee and definately worth the extra splurge if you are wanting to treat yourself :)
oh and p.s. How lush is the YSL packaging!!!
