How sleek is Guerlain’s Rouge G de Guerlain Jewel Lipstick Compact ($45)? Its all metal case was designed by Place Vendome jeweler Lorenz Baumer and it features a double mirror and comes in 25 shades. The new formulations is supposed to be lightweight, long-lasting, and highly pigmented. It’s also formulated with hyaluronic acid microspheres which is a lip plumper. I tend to stick with gloss so I haven’t tried this for myself, but I saw it at Bergdorf and love the look of this lipstick — very obviously inspired by jewelry making. Rouge G has a hidden hinge and there’s also a light clicking noise when the lipstick is removed from its case which causes the case, with its double mirrors, to flip open. Guerlain is engraved on the lipstick case.
