Fine lines and wrinkles are visible signs of aging that develop due to natural skin changes and repeated facial expressions. Fine lines tend to appear first, often as shallow creases around the eyes or mouth, while wrinkles are deeper and more prominent. These changes are caused by the gradual breakdown of collagen and elastin, the proteins responsible for skin’s firmness and elasticity. Environmental factors, such as sun exposure, can accelerate their appearance, leaving skin looking aged and less vibrant. Addressing these signs can help restore a smoother, refreshed, and more youthful look.
