Brow Define is the only product I use on my eyebrows now because it's so easy and lasts all day. The crayon itself is very thin so I can fill in and shape my brows without overdoing it and the spoolie on the other end is super handy for grooming. I've tried other pencils that look great at the start of the day but slide off my oily skin, but this one is so much more longer lasting!
I've over-plucked my eyebrows for almost 40 years and they were so thin and patchy. I was very self-conscious about how they looked. Then someone in a brow bar showed me how to use this smudge pen. I was skeptical initially, but it's so easy to use and it WORKS and doesn't look fake or painted in! I'm really impressed - and grateful.
I'm actually pretty hard pressed to work out which I prefer, the Brow Define or the Brow Duo? I think this one is better if you just want to fill in a gap or two or refine your brow tail. I like the spoolie that comes with this - super convenient, and not too hard.
Personally I hate having to worry about sharpening pencils and this one is also the perfect size. It's not too hard or too soft, and its easy to get brow-identical hairs. Colour range is great too!
