Lancôme Définicils Defining & Lengthening Mascara — Full-Size Black, Lightweight Conditioning Lash-Lengthening Finish

Lancôme Définicils is a defining and lengthening mascara that delivers naturally long, separated lashes with a flake-free, non-clumping finish.

Designed for everyday wear, Définicils blends a lightweight polymer formula with panthenol (Vitamin B5) to condition lashes while visibly lengthening and separating them. This full-size black mascara is celebrated for its clean, natural look and comfortable wear—earning recognition such as the 2024 Allure Best of Beauty award. The brush and formula work together to lift each lash, keeping eyes looking open and defined without heavy buildup.

How does Définicils create a lengthened, natural lash look?

The formula focuses on lightweight length and separation rather than dramatic volume. Polymers coat and extend each lash while the precise brush helps comb them apart, producing a clean, elongated silhouette that reads as natural on the eye.

• Slim, tapered brush targets inner and lower lashes for even coverage
• Polymer-based formula elongates without adding weight
• Black shade deepens lash line for subtle definition
• Buildable application lets you increase length without clumping

Will this mascara flake or clump during the day?

Définicils is formulated to resist flaking and to separate lashes for a tidy, groomed finish. With its smooth polymer blend, the mascara is engineered to maintain lash separation and prevent flaky residue throughout wear.

• Non-clumping texture layers cleanly for multiple coats
• Polymers help the finish remain intact and brushable
• Long-wearing formula reduces fall-out that creates flakes
• Removes easily with oil-based or bi-phase removers when needed

Is Définicils suitable for sensitive eyes and daily use?

Yes—Définicils is created with tolerance in mind and is marketed for sensitive eyes, providing comfortable all-day wear. The inclusion of panthenol (Vitamin B5) helps condition and strengthen lashes between uses, making it appropriate for frequent application.

• Formulated for sensitive eyes to minimize irritation risk
• Panthenol nourishes lashes during wear
• Lightweight texture reduces rubbing and discomfort
• Recommended removal with Lancôme Bi-Facil for gentle cleansing

How do I apply and remove Définicils for best results?

Apply from root to tip with a wiggling motion to deposit lengthening formula at the base and sweep through the ends for separation. For removal, an oil-based or bi-phase eye-makeup remover dissolves the polymer formula without vigorous rubbing.

• Start at the base, wiggle gently, and comb to the tips
• Build by layering thin coats rather than applying a single heavy coat
• Cleanse with Lancôme Bi-Facil or similar gentle remover
• Pat with a cotton pad to dissolve product, then rinse

Who is this for: Lancôme Définicils suits anyone seeking a refined, everyday mascara that emphasizes length and separation over dramatic volume. It’s ideal for those with sensitive eyes, wearers who prefer a natural finish, and anyone who wants a reliable, non-flaking mascara that conditions lashes while defining them.
