Physicians Formula Eye Booster Super Slim Waterproof Eyeliner – Ultra Black

Meet a precision liner built for everyday definition and bold artistry. The Physicians Formula Eye Booster Super Slim Waterproof Eyeliner uses an ultra-fine brush tip to help you craft anything from a barely-there line to an eye-opening wing. The deep Ultra Black shade glides on with creamy control, warming to a rich, even finish as you steady your hand. Because it's waterproof, the formula dries quickly and resists smudging through sudden humidity, splashes, or long days. The liner is part of the Eye Booster family, designed with a Lash-Boosting Complex to support the appearance of lashes with regular use. For sensitive skin, the product is formulated with skin-first ingredients and tested for safety; it’s also cruelty-free and vegan, aligning with ethical beauty values. In short, it’s a versatile tool for a wide range of looks and occasions, without compromising comfort or ethics.
