The upper perioral area is one of the most dynamic regions of the face, constantly engaged during speaking, smiling, and expressive movement. Over time, repetitive muscle activity combined with thinning skin can lead to fine vertical lines above the lip.
Natural collagen and elastin loss reduces the skin’s ability to rebound, allowing lines to become more visible even at rest. Environmental factors such as sun exposure, dehydration, and smoking can further accelerate these changes. For many, lines in this area can affect lip definition and create an appearance of aging that feels disproportionate to the rest of the face.
