A well-groomed pair of brows will take you far. Before tweezing, prep them by softening your pores with a hot shower. Natural, full brows are in style, so tweeze sparingly. Imagine a straight line from the corner of your nostril to the outer corner of your eye and brow. That’s where your brow should end. Now imagine a line from your nostril through your iris—that’s where your arch should peak.
