I have found that the best lighting for tweezing brows happens to be in the car -- no joke. Without fail each morning as I sit in Los Angeles traffic, I flip open my visor mirror and -- bam -- I see each and every stray hair that I somehow missed, or more like, never saw. You really need quality light to pluck brows -- ask any pro.

Which is why on this third day of reporting live from Cosmoprof North America, my "best in show" beauty product pick of the day are the La-Tweez Pro Illuminating Tweezers, $24. These are the Porsche of tweezers. Not only do they have a super sharp, precise, stainless steel design (with handy triangle cutouts along the sides for improved grip), but these babies light up. With one touch of the very snazzy Swarovski crystal button, on pops a very bright LED light that helps you see each and every hair -- even my fine blonde ones. And the light has auto shut-off to boot.

They pretty much thought of everything in designing this beauty tool -- maybe next year's edition will have an auto-pluck button, here's hoping. Until then, make sure you avoid the most common eyebrow tweezing mistakes by following these expert tips, courtesy of brow guru Kristie Streicher.
