Wrinkles and aging skin are natural outcomes of the aging process, primarily caused by the gradual breakdown of collagen and elastin—two essential proteins that provide skin with structure, strength, and elasticity. Over time, the production of these proteins slows down, leading to a loss of firmness, increased sagging, and the formation of fine lines and deeper wrinkles.

External factors like ultraviolet (UV) exposure accelerate this process by damaging collagen fibers, causing premature aging known as photoaging. Other elements such as pollution, smoking, and repeated facial movements also contribute to the weakening of the skin’s supportive framework. As the skin’s ability to repair itself diminishes, it becomes thinner, drier, and less resilient.

Understanding these changes is crucial for effective skincare, which focuses on supporting collagen and elastin health to slow visible signs of aging and maintain skin’s youthful strength and flexibility.
