The forehead is one of the most active areas of the face, constantly engaged through everyday expressions like raising the brows, squinting, or reacting emotionally. Over time, these repetitive movements can cause the skin to crease, forming horizontal lines that may remain visible even at rest.
As collagen and elastin naturally decline with age, the skin becomes less resilient and less able to bounce back from movement. Environmental factors such as sun exposure, stress, and dehydration can further accelerate this process. For many, forehead lines can create an appearance of tension, fatigue, or concern that doesn’t reflect how they actually feel.
