Our take on the Lancôme Cils Booster XL Super-Enhancing Mascara Primer

Cils Booster XL is a white mascara primer that goes on before your regular mascara to add length, volume and curl. It is built around micro-fibers and vitamin E, and Lancôme says it conditions lashes while it works. It is ophthalmologist and dermatologist tested, hypoallergenic and free of parabens, alcohol and silicone, which is why it is often recommended for sensitive eyes. The best new price is $30.00 at Kohl's as of November 5, 2026, well above the recent daily low of $12.00 on November 1 and the recent high of $16.00 on November 6.

Pros
  • Adds visible length and volume under almost any mascara
  • White tint shows you where you have coated, so coverage is even
  • Micro-fibers and vitamin E condition lashes as it primes
  • Ophthalmologist and dermatologist tested, hypoallergenic
  • Paraben-, alcohol-, silicone- and gluten-free, and vegan
  • Washable formula that removes with warm water and cleanser
Cons
  • Needs a mascara on top; worn alone it leaves a white cast
  • Can clump if you apply too much or skip the zigzag motion
  • The triangular brush takes a few tries to get used to
  • Costs more per tube than many drugstore primers

With about 19,000 ratings averaging 4.6 out of 5, owners mostly report longer, fuller-looking lashes and less smudging from their regular mascara. Sensitive-eye users say it does not sting.

Questions and answers

Is Cils Booster XL worth it?
If your lashes are short, sparse or prone to smudging, most owners say yes: one coat adds visible length and volume and helps mascara last. If you already have long lashes and a mascara you like, the gain is smaller for the price.
How do I use it?
Coat lashes with the primer using a zigzag motion from root to tip, then apply your regular mascara right away, before the primer dries. Do not let it dry white and then try to layer mascara over it.
Can I wear it alone?
It is a white primer, so worn alone it leaves a visible white cast. It is meant to sit under a colored mascara.
Is it safe for sensitive eyes and contact lenses?
It is ophthalmologist and dermatologist tested and hypoallergenic, and many sensitive-eye users report no irritation. If you have a known allergy to any ingredient, check the full list first.
How is it different from Cils Booster XL's predecessor, Cils Booster?
Cils Booster XL is the newer, larger-tube version with a triangular brush and a fiber-infused formula aimed at more volume. Owners of the original often describe XL as giving a bigger lash boost.
When is the best time to buy it?
The recent daily price ran from $12.00 on November 1 to $16.00 on November 6, 2026, while the best new price was $30.00 at Kohl's on November 5. Watch for department-store beauty sales and gift-with-purchase events, when the effective price drops.
