What it is: The magic of Touche Eclat is now in Yves Saint Laurent's first awakening foundation with more fatigue-defying and even better flawless coverage than ever before. What it does: Enriched with the stimulating power of ruscus extract, the anti-fatigue formula energizes skin by stimulating micro-circulation and targeting dullness to instantly improve skin brightness and luminosity. Vitamin E protects against free radicals. The weightless foundation leaves you with eight hours of a fresh, radiant complexion. How to use: The foundation should be applied with the new Touche Eclat Le Teint Brush (sold separately), a Y-shaped brush that delivers the perfect amount of foundation. Simply pump two drops into the brush well, then buff over skin. It distributes product evenly for a seamless, flawless finish every time.
