For all-day eyebrow color, use product as an overnight eyebrow stain. Apply product after cleansing and drying your face. Make sure your eyebrows are free of any skincare product or oil. Draw your desired eyebrow shape and go to bed. For best results, leave on for 6 to 8 hours before washing your face. For use as an eyebrow liner, apply before skincare and makeup products to prevent the felt tip from clogging. If clogging occurs, wipe the tip with a clean tissue.
