Great alternative to brow gels, pencils, and powders.
I've been using the dark brown tint in this brand for years and have never had a problem.  My hair color is lighter than 'dark brown' but darker brows look nicer on most people because it gives more definition to the face.  The only thing you want to be careful with is making sure you give yourself enough time after application to get it off the skin.  Some people use a cream or Vasoline around the brow, so it doesn't tint the skin.  I apply it at night, remove it with eye makeup remover (oily liquid on a cotton round), and then the next morning wash my face. It comes off the skin without issue for me and the skin around my brow isn't raw from scrubbing.  Whatever you do, if it's your first time using a brow tint,  don't apply it right before an event, date, or work.  Give yourself time to learn how to use the product, i.e. not end up with brows too dark or with tinted skin you are panic scrubbing to get off.  Sometimes, when I want a more dramatic look or the color is fading, I will still manually define my brows, but for my everyday look, the brow tint is enough.
