A pale stain seems like a veritable impossibility. That is one of the reasons that Yves Saint Laurent's glossy stains in Rose Pastelle (reviewed HERE) and Beige Aquarelle (#19) were so intriguing to me.
While Rose Pastelle has a very cool pale pink (almost border lining on lavender) undertone, Beige Aquarelle (which retails for $32) translates as a warmer, pinky-peachy shade.
When applying it on your lips, the creamy pale nature of the product makes it hard to believe that it will yield any observable color at all...however, after a couple of coats and a few minutes, the stain miraculously deepens to a light peach.
To get the most out of this product, application is key: I like to start with exfoliated lips (this shade, while not drying, tends to highlight any existing dryness) and then layer on two coats. At this point, it is essential to let it dry for 15 seconds or so; then, apply another coat or two. This process results in a pale peachy pink lip that is shiny and set to deepen as time marches on.
