Our Verdict
The Lancôme Cils Booster XL Super-Enhancing Primer delivers on its promise of enhanced lash volume and length, acting as a superb base for mascara. Its creamy texture applies smoothly without clumping, significantly improving mascara application and longevity. However, at its price point, the value proposition is debatable. While the effect is noticeable, it's not transformative for naturally lush lashes. Therefore, purchase is recommended for those seeking a noticeable lash enhancement that improves mascara performance and justifies the premium price. Those with naturally voluminous lashes or on a tighter budget might find the cost outweighs the benefit, opting instead for a more affordable volumizing mascara. Ultimately, its usability is excellent, but its value depends on individual needs and expectations.

Who Should Buy
This lash primer is perfect for anyone who desires noticeably longer, fuller lashes. If you're looking to enhance the performance of your mascara, giving it extra staying power and preventing smudging, then this is the product for you. It's ideal for those who want to create a dramatic, voluminous look without the weight or clumpiness of multiple coats of mascara. Whether you're a seasoned makeup user or just starting out, this primer offers a simple yet effective way to elevate your lash game and achieve the ultimate eye-opening effect. Its versatile formula works well with a variety of mascaras, allowing for customization and flexibility in your makeup routine.
Who Should Not Buy
This product might not be the best choice for those seeking a completely natural look. While it enhances lashes significantly, it does add noticeable volume and length. If you prefer a subtle, understated lash look or are sensitive to even mild fragrances or preservatives present in some cosmetics, you might want to explore other options. Those with extremely sensitive eyes or those allergic to common cosmetic ingredients should always conduct a patch test before full application. Ultimately, the decision to purchase depends on your individual preferences and desired results.
Sensitive
This lash primer is formulated with consideration for sensitive eyes. While not explicitly labeled "hypoallergenic," Lancôme strives for gentle formulas, utilizing ingredients that are less likely to cause irritation. However, individual sensitivities vary. It's always advisable to conduct a patch test on a small area of skin before applying the primer to your entire lash line. Pay close attention to any reactions such as redness, itching, or burning. If any irritation occurs, discontinue use immediately and consult a dermatologist if necessary. While many find it comfortable to use, individual sensitivities can differ significantly.
Volumizing
This primer's primary function is to dramatically increase lash volume. Its unique formula is designed to coat each individual lash, adding thickness and creating a fuller, more voluminous appearance. The buildable formula allows for controlled application; you can adjust the amount used to achieve your desired level of volume. This feature is beneficial for creating various lash looks, from naturally enhanced to dramatically bold. The result is lashes that appear significantly thicker and more abundant, making your eyes appear larger and more expressive.
Lengthening
Beyond volume, this lash primer also delivers noticeable length enhancement. The lightweight yet effective formula lengthens lashes without weighing them down or causing them to clump together. This is achieved through a specialized blend of polymers and conditioning agents that effectively coat and extend each lash, creating a longer, more defined look. The added length enhances the overall impact of your mascara, resulting in an effortlessly glamorous appearance. Paired with a lengthening mascara, the results are truly transformative.
Tubing
This lash primer does not utilize a tubing mascara formula. Tubing mascaras coat each lash in a protective film, creating a more resistant, smudge-proof finish. This primer instead works by creating a base layer that adds volume and length to enhance your subsequent mascara application. While this primer doesn’t offer the tubing mascara’s unique properties, it still provides significant enhancement and improves mascara performance, reducing clumping and enhancing the longevity of your lash look.
Curling
While not designed as a lash curler, this primer helps to enhance the curl of your lashes. By creating a thicker, fuller base, the primer provides support for the natural curl of your lashes, and helps mascara to adhere better. This prevents lashes from drooping and keeps them lifted for a more wide-eyed, expressive look. Applying this primer before curling with a lash curler can also help set and protect the curl. While it won’t create a dramatic curl on its own, it contributes to a more defined and longer-lasting curl.
Hypoallergenic
While many find this product gentle, it's crucial to remember that "hypoallergenic" doesn't mean it's completely reaction-free. This is not explicitly labeled hypoallergenic. Individuals with sensitive eyes should perform a patch test before full application to assess any potential reactions. Ingredients can vary from batch to batch and individual sensitivities are unique. Always check the ingredient list for any potential allergens you may have and consult with a dermatologist if you have concerns or prior sensitivities to cosmetic ingredients.
Vegan
This product's vegan status is not explicitly stated by Lancôme's official product descriptions. To ensure it's suitable for a vegan lifestyle, it is important to check the product packaging, or to contact Lancôme's customer service directly for clarification regarding the ingredients and their sourcing. Many cosmetics brands are increasingly transparent about their ingredient sourcing and ethical practices, so checking the brand's official channels is always recommended before making a purchase. Look for certifications or statements on the product packaging or website to confirm.
Clumping
This primer is designed to prevent clumping, a common issue with many mascaras. Its lightweight formula smoothly coats each lash, avoiding the build-up of excess product that leads to clumping. It creates a uniform base layer for your mascara, allowing it to apply evenly and separate lashes effectively. This results in a naturally fuller, more defined lash look without the undesirable clumps that can weigh down lashes and detract from a polished finish. The primer's smooth texture aids in preventing mascara from clumping together, enhancing the overall lash appearance.
