By now I'm sure you've all heard about Yves Saint Laurent Touché Éclat highlighter ($39.50). This cult beauty product has legions of celebrities who use it, and it's received a load of press in magazines. But does it live up to the hype?

After using this for a few months, I can tell you that it does! But it all depends on what your expectations are. For those of you anticipating a concealer, this will disappoint. A lot of people think it's a concealer, but Touche Eclat is actually a highlighter. It's meant to reflect light off the skin, making under-eye circles and nose creases less visible.

The Touche Eclat formula comes in a pen, and to push up the product, you just twist it once until it clicks. The highlighter then oozes onto a brush, which I use to dab onto my dark circles. Then I gently press and pad the highlighter (rather than brushing it on).

The thing I like about this product is that it doesn't look makeuppy at all, but the skin looks brighter and more luminous. Layered on top of concealer, it keeps makeup from looking cakey or masklike. It brightens up the face just a little, just enough to perk me up when I look worn out. For that alone, I think it's worth the price.
