Frown lines often develop between the eyebrows and can influence how the face appears at rest. While they’re closely tied to expression, a tailored approach can help reduce their appearance while maintaining natural movement.

Frown lines are vertical creases that form between the eyebrows, often referred to as “11 lines.” They may appear with concentration or expression at first and gradually become visible even when the face is relaxed.
Because this area is central to facial expression, changes here can subtly affect how emotions are perceived.
Repeated contraction of the muscles between the brows plays a significant role in the formation of frown lines. Over time, skin elasticity decreases and collagen production slows, allowing these lines to become more pronounced.
Sun exposure, stress, and natural aging can further contribute to how deeply frown lines set.
