pply Brow Microfilling Pen on clean, dry brows—that means no moisturizer, no other brow products, nada! The ink-like formula can’t adhere properly to brow hair or skin if anything stands in the way. Starting at the front of your brow, flick up in short, gentle strokes following your natural brow shape. Once you get to the arch, turn pen sideways & angle it down toward your temple. Then stroke in diagonal downward motions to fill in the tail. Then, feel free to layer other brow products on top!
