I posted about this product in a haul a little white back. It's the second YSL beauty product I've ever bought, and the beauty range from this brand continues to impress me with each new purchase I make.
I own a Volupte Shine already, but I was attracted to the formula of this particular product. The packaging is very sleek and lovely, and the cap clicks into place so it is never askew or comes loose (a personal peeve of mine). The formula itself is creamy and silky right out of the tube, and applies like a dream. The angled, wide applicator makes it very easy to apply to the lips, at least for me. Once applied, the formula quickly begins to dry into a semi-matte finish, and pretty much becomes the "stain" part of its name. Once dried, this stuff sticks to the lips and takes quite a bit to come off. Re-applying is a breeze, and doesn't over-dry the lips.
I'm so in love with this product, and I'm dying to buy more, as well as more products from YSL in general. It isn't cheap, but the quality and feel of the formula feels worth the $35 in my opinion. I'm not at all disappointed with this product. Even the color is so flattering and smooth, and I'm dying to try out a few other colors (looking at you #2).
For reference, I own the #9 Rouge Laque.
