Lengthening Mascara — Définicils by Lancôme
The secret to effortlessly elegant eyes: this Lengthening Mascara from Lancôme has been a cult favorite for decades, beloved for its ability to create clean, defined, natural-looking lashes without the drama of clumps or flakes. Définicils relies on a smart formula of lengthening polymers, panthenol and vitamin B5 to gently extend each lash while conditioning it over time. The precision comb brush features a unique “hedgehog” bristle pattern that grabs every single lash — even the tiniest corners — for gradual, buildable, perfectly separated results.
