Forehead lines often develop gradually and are closely tied to facial movement and expression. While they’re a normal part of how the face functions, targeted care can help reduce their appearance without compromising natural expression.
Forehead lines are horizontal creases that appear across the forehead, becoming more noticeable with movement and, over time, at rest. They may start as fine lines and deepen gradually as skin support changes.
Because the forehead plays a major role in expression, these lines often reflect how frequently the muscles in this area are used.
Forehead lines are primarily caused by repetitive muscle movement combined with age-related changes in skin elasticity and collagen production. Sun exposure and environmental stress can further contribute to how quickly lines become visible.
As these factors work together over time, lines that once appeared only with expression may begin to remain when the face is relaxed.
