The YSL Le Teint Touche Éclat Foundation is probably one of the most eagerly awaited products to hit the beauty counters with YSL describing it as: "A bold, unique formula to target shadowy areas and define contours. A magic light infused within a weightless fluid. A texture that has no mask-like effect. A formula free of opaque powders that evens the complexion and erases imperfections, enhancing the face’s natural features."
At £28 it is not cheap but I've found (well, the Martin Money Tips weekly email alerted me) a great deal where you can get a free 5ml sample of the foundation. Simply 'Like' the YSL Facebook page, print the voucher and take it to your nearest YSL counter.
YSL will find the right match for your skin and you will be given a free 5ml glass bottle. Brilliant!
