Sisley has the actual best skincare products ever. Unlike so many other high-end brands with crazy claims that people swear by (ahem, La Mer), these work. However, I don't know if they are $510 worth of work: the Sisleya Radiance Anti-Aging Concentrate claims to renormalize the skin's "metabolism" to function the same way it did when it was young. Okay, so I want this, what of it? Sisley also offers Supremya (shown), "the comfort of a night cream with the concentration of a serum" that will "enable the skin to gradually charge itself with active ingredients" for $775. I'll take one of those, too.
