Does the jawline go away with age? Understanding the causes of facial aging
According to a 2011 study published in the journal Plastic and Reconstructive Surgery, the facial skeleton undergoes significant changes with age, including bone resorption in the jaw. While a strong jawline doesn't 'go away' completely, it can become less defined and more susceptible to sagging due to a combination of factors, including bone loss, reduced collagen and elastin, and the downward migration of facial fat. This natural process leads many to seek ways to preserve or restore their youthful facial contours.
