Scarlett Johansson's Must Haves: From a Prada Purse to a Niacinamide Cream

To ensure her eyebrows are clean and shapely 24/7, Johansson relies on this Tweezerman Slant Tweezer ($24), which is a staple in her everyday beauty bag. It boasts an unbeatable price tag to boot.

Pro Tip: Unlike other tweezers, this set is designed with a 25° slant tip that's optimized to work better with the shape of the brow bone. To preserve the product's quality, the brand recommends cleaning the tweezer tips with alcohol wipes or peroxide after each use.
