Shu Uemura offers a range of eyebrow pencils, including some that are specifically designed to be waterproof. However, not all Shu Uemura eyebrow pencils are waterproof, so it's important to check the product description or packaging to determine if a particular eyebrow pencil is waterproof. The waterproof formula is designed to provide long-lasting wear and resist smudging or fading, making it suitable for activities where water or sweat may be a factor.
