As we age, facial asymmetry tends to become more pronounced due to the natural weakening of muscles on one side of the face while the other side remains stronger.
While it's common to notice these differences in your 20s and 30s, they often become more noticeable over time. Rejuvenative surgery can help reduce these asymmetries, but aiming for perfect symmetry is unrealistic, as changes will naturally occur as you continue to age.
Accepting some level of asymmetry is essential for a lasting, natural appearance.
