L'Oréal Paris Limited Edition Valentine's Day Paradise Mascara (£12) is something to celebrate. The original formula is hailed as one of the best by makeup artists around the world, due to its "perfect brush size, full volume, and zero clumping," says British makeup artist Hannah Martin. Well, this year, it's getting an adorable makeover for Valentine's Day. The formula and brush will stay the same, but for February, it'll get a new heart-embellished design.
