What if a contour powder can actually slim down your face - for good? That's the amazing proposition of the Snoe Slim Shade Me Face Sculpting Cake (P799). It claims to literally contour your face over time, with ingredients like coffee (to firm and tighten skin) and Magnolia Bark Hot Water Extract (to supposedly prevent fat accumulation and creation).
Coffee or caffeine is a common ingredient in cosmetics nowadays, since it's an effective way to quickly tighten skin. It constricts blood vessels and slightly dehydrates the skin thus effectively de-puffing the area. Caffeine is especially useful in eye creams! As for Magnolia Bark extract, I am not so sure. If it were that simple, everyone would be bathing in the stuff. Why bother with dieting, amirite?
So yes, I would suspend belief about the permanent face slimming properties of any powder. :) That aside I do like the Snoe Slim Shade Me because the color is great for contouring, it's smooth, and it has a good staying power due to the amazonian clay in it.
