The lips are composed of delicate skin, soft tissue, and supportive structure that naturally change with age. Over time, collagen and hyaluronic acid levels decline, leading to loss of volume, definition, and hydration. The vermilion border can soften, and lips may appear thinner or less balanced than they once were.
Environmental factors such as sun exposure, dehydration, and repetitive movement can further contribute to fine lines around the mouth and changes in texture. Genetics also play a role in lip shape and fullness. For many, these changes can subtly alter facial balance or make the lips appear less expressive, even when the rest of the face feels unchanged.
