The L'Oreal Paris Colour Riche Anti-Aging Serum Lipstick is a discontinued lipstick line that featured a unique "serum core" design. The lipstick was distinguished by a visible teardrop-shaped center containing an anti-aging serum, which was formulated to hydrate lips, minimize the appearance of fine lines, and provide a plumping effect.  Key Product DetailsUnique Design: The lipstick bullet featured an internal core enriched with active ingredients like ProXalyne, Collagen, Hyaluronic acid micro-spheres, and Glycerin.  Primary Benefits: It was designed to improve lip definition, fill surface lines, and offer a creamy, moisturizing application.  Formula & Feel: The formula was described as soft and creamy. Some users noted a slight tingling sensation due to the plumping agents.  Availability: As this is a discontinued product, it is no longer available through major retailers like the official L'Oreal website. It can occasionally be found through secondary marketplaces or specialized "hard-to-find" beauty retailers.
