YSL knows that the perfect finish to any make-up look is a sultry lip, and the Rouge Pur Couture lipstick delivers just that with a new formula inspired by Monsieur Saint Laurents iconic colour palette made up of reds, pinks and oranges. Presented in a luxurious golden case that doubles as a handy mirror, the sumptuous formula glides on, saturating lips with intense, stay-true colour for up to six hours, all while coating the lips in a blend of hydrospheres and natural extracts that ensure all-day moisture and hydration.
