To give you an idea how her brows looked before and after the brow pen, here is a screen grab of one arch finished and the other still makeup-free. As you can see, there is a noticeable difference, and the filled-in brow does still look natural and has a hair stroke effect. As Yong explained, the pen comes in three shades: natural brown, red brown, and grey brown. As she tested the pens on her hand, she did notice that the formula is a little bit runny and bleeds out on the hand. When she finished both borws she gave her final opinion, and she was pleased to note that the product didn't bleed the way it did on her hand, and was pretty budge-proof if not 100 percent smudge-proof. She noted that the press release said that it was supposed to last up to 24 hours, but when Yong tested that claim she did find that it noticeably disappeared off of her brows at the end of feather brow tattoo the day.
