YSL's Rouge Vibration is very similar, if not identical to Chanel's Infrarouge formulation. A weightless, color intense lipstick whose formulation I will love, love, love until they discover the ultimate lipstick formulation that combines moisture, non-caking texture and staying power. The colors are very beautiful in this range and incorporates a beautiful shimmer/subtle metallic sheen. #8 is like a dark garnet red, leaning towards the brown side. It truly feels weightless and lasts longer than the other YSL lipstick formulations. I like this as much as Infrarouge and it has that lovely YSL rosey smell. For something that feels this good on lips, I'm happy with its longer than average staying power. Packaging is also a very understated chic all-black slim square which I prefer over the overtly gold packaging of the regular YSL products. Only rant - pricey at $28.00 for a less than average amount of product.
