How does Définicils Mascara compare to other Lancôme mascaras?
Définicils is Lancôme’s iconic defining mascara, focused on lengthening and natural separation versus volume or curl. Its comb-like hedgehog bristle pattern dispenses the perfect amount of product for clean, precise, flake-free, non-clumping results.
How do I apply Définicils Mascara for best results?
Prep lashes with Cils Booster XL. Begin with bottom lashes, placing the wand at the root and wiggling to add depth. Comb through in smooth vertical strokes. Layer on outer corners to lift and extend. Use the tip of the brush for lower lash precision.
How long does Définicils Mascara last?
Définicils Mascara is formulated for long-lasting, smudge-proof wear. Its flake-free, non-clumping formula keeps lashes defined throughout the day. To remove, Lancôme recommends Bi-Facil Double Action Eye-Makeup Remover for a clean and gentle result.
Will Définicils Mascara clump or flake?
No. Définicils Mascara features a flake-free, non-clumping formula. Its comb-like hedgehog bristle brush separates lashes precisely from root to tip, dispensing the perfect product amount for clean, defined, and naturally striking lashes, every time.
Is Définicils Mascara waterproof?
This specific mascara is not waterproof, but it does feature a flake-free, non-clumping formula that defines and lengthens lashes naturally from root to tip! If you prefer a waterproof formula, be sure to look for our Définicils Waterproof Mascara.

Lancôme Définicils Defining & Lengthening Mascara is an iconic lash favorite and 2024 Allure Best of Beauty Winner. Its advanced polymer formula coats lashes from root to tip with zero flaking or clumping for longer, perfectly outlined, naturally defined results. Designed to lift, lengthen, and separate, it creates clean definition that looks elegant, polished, and never overdone while leaving every lash beautifully distinct and naturally extended.
The smudge-proof, lightweight formula lifts and lengthens lashes for all-day definition without a heavy feel. The grooved bristle brush separates each lash with precise control, ensuring clean, even, clump-free application and the perfect amount of product at every stroke. Lashes look longer, more lifted, and beautifully defined from root to tip, with a naturally outlined finish that stays polished, separated, and never overdone from day to night.
Enriched with Panthenol and Vitamin B5, this lengthening mascara conditions lashes while defining them for comfortable daily wear. Gentle enough for sensitive eyes and contact lens wearers, the ophthalmologist-tested formula helps create longer, naturally defined lashes with a clean, clump-free finish you can wear confidently every day. The result is soft, separated definition that feels light, comfortable, polished, and easy to wear.
Carefully selected polymers grip each lash from root to tip to lift, lengthen, and separate with precision. The result is longer, thicker-looking, naturally defined lashes that appear beautifully distinct — never stuck together, never heavy, and never overdone. Définicils delivers clean lash definition for an elegant, outlined eye look with polished length, precise separation, and naturally enhanced lashes that stay refined.
Place the Définicils wand at the root of lashes and gently wiggle back and forth, then pull through to the tip for length and definition. Layer on outer lashes to lift and extend the look of lashes. Prep with Cils Booster XL for amplified results, then remove mascara with Bi-Facil Double Action Eye Makeup Remover for a clean, comfortable finish. This routine helps keep lashes defined, lifted, extended, and beautifully separated with every application.
