Extremely popular highlighter, Yves Saint Laurent's Touche Eclát comes in a pen applicator which delivers the product by clicking the pen. The package has a sophisticated touch and is very portable (great to carry around).
It is a liquid concealer that comes in 8 shades (all somewhat light, as this is mainly an highlighter) and has a creamy, sheer texture.

I bought this about an year ago, to conceal dark circles, but never used it much because it doesn't do the job much better than a dab of my regular Clarins foundation.

However, I began to use it again recently and even thought this is not a great concealer, it works fine as a brightener and surely gives my face some glow.



It is lightweight, and can be used as an highlighter (cupid's bow, nose bridge, eyebrows or cheek's bones) or as a concealer for small imperfections or not very severe dark circles (I figured it works it's best if applied before a tiny bit of foundation).
 Touche Eclát is also good to make you look awake if applied to the inner corner of the eye.

The worst aspect of this is definitely it's price. In my opinion, it's overpriced for what it does, but I'm yet to try other similar products before I can give my take on if it's worth it or not.
