Identifying the clinical signs of brow descent
Most of us are aware of the importance of facial expression in conveying a message to the people around us. We frown to show discontent and we smile to show happiness and joy. As we age our face may adopt a permanent expression of anger or sadness, even though we feel happy and full of energy. This is characteristic of people with a low eyebrow.
Several factors play a role in the position of our brows, such as gender, genetic background, and the loss of volume induced by aging. Together they determine the time and severity of brow descent. Inevitably, the brow will sag under the weight of gravity, producing the characteristic overhang of skin in the upper eyelid, i.e., lateral hooding.
