All colours of the Yves Saint Laurent Volupté Plump-in-Colour Plumping Lip Balm ($26, originally $39) have cooling peppermint oil along with moisturising hyaluronic acid and coconut oil in a black heart-shaped core . . . but each one is boldly different. There are luscious fuchsia, orange, coral, champagne, and nude shades still on sale now.
