Universal Brow Definer is a remarkable one-color-fits-all eyebrow pencil that scientifically reads - and automatically color adjusts to - the pH of your eyebrow hair follicle. No joke! Universal Brow Definer is specifically designed to simulate the look of eyebrow hairs. Upon touching the eyebrow area, it automatically color-adjusts from light to dark, warmer to cooler, etc., to match all natural eyebrow hair shades - from Platinum Blonde to the deepest Brunette.
