Jo Malone’s new bath oil sounds almost like molecular cuisine. It promises to gently fizz up upon contact with your bath water before creating a milky emulsification. As if that wasn’t intriguing enough, this “oil” is non-oily: no film on the surface, no residue on your skin. It might not be as relaxing as being on vacation, but this weekend, you can at least turn your home into a spa. Choose from lime, basil, mandarin, grapefruit and pomegranate noir.
