SEPHORA COLLECTION Size Up Mascara New 2020 Ultra Black 01

Product Information

When our Beauty Lab pros test mascara, we start by rounding up hundreds of the most popular mascara formulas on the market and then whittle down the field. We test each product for performance, wearability, ease of application and consumer satisfaction. For waterproof mascara, the Lab monitors results as testers doused their mascara-coated lashes in warm water to see how well each product resisted smearing and running. We've tested hundreds of mascaras over the past decade, but in our most recent test, experts tested 10 mascaras individually and evaluated them across 40 surveys, resulting in over 100 data points and comments.
