To this day, my mother is one of the most fashionable, stylish, beautiful women that I know. For as long as can remember (and probably far beyond even that), her nightly routine included washing her face and then filling in her eyebrows with a pencil and applying some kind of color to her lips. She always made a point of being presentable at all times (even in her sleep). I never understood the point of taking off makeup just to put some back on, but now that I'm married, it makes more sense.
Another thing I never really saw the point of was filling in my brows. I've made sure that they were in a neat, natural looking arch since my early teens, but other than that (semi) regular maintenance, I left my brows alone. Enter YouTube and every gurus obsession with brows (and my personal realization after a terrible growing out period that helped me to see that they truly can make or break your look) and now I've been on a quest for the right technique and products for my brows.
