I am usually a fan of brow powder because I like a very natural brow, but one thing a powder does not do, that "Brow Power" can do is stand up to water and sweat so it's perfect for a day at the gym or the pool. And because its a pencil that twists up (with a spoolie at the other end) there is no need to carry around a powder plus a brush.
As I mentioned above, this is a universal color, a lighter hand will equal a lighter color. I did find it was a little bit harder to match my black eyebrows than it was to make the lighter colors.
Another HUGE benefit to this product is for every purchase of one of their Brow Powder Pencils, they will donate another Pencil to the American Cancer Society's "Look Good, Feel Better Program"
