As we age, things start to sag that didn't sag before, and as a result, we begin to look older. One of the first things to sag or droop is our eyebrows. The muscle that holds the eyelids and eyebrows up in their proper position becomes strained or overworked causing the eyebrows and the upper lids to slide down. Drooping brows can make us look older, and make us feel self-conscious or embarrassed. It may make you appear angry or upset even though you're not. They also cause wrinkles in the browline and around the eyes and can also impede your vision, making it hard and dangerous to drive.
