As you age, your skin starts to change. It slowly loses firmness and elasticity, which leads to sagging skin—especially around the cheeks, jawline, and neck. This happens because your body produces less collagen and elastin, two proteins that keep your skin smooth, tight, and supported. These changes usually begin in your 30s and become more noticeable over time. Other things also speed up the skin aging process—like sun exposure, pollution, and certain lifestyle habits. Over the years, these factors affect the deeper layers of the skin, weaken connective tissue, and cause volume loss in areas that used to feel full and firm. Understanding how aging affects your facial structure, skin tone, and collagen production is the first step toward finding the right ways to support your skin. Whether you're curious about dermal fillers, skin tightening, or non-surgical treatments, learning about the causes of saggy skin can help you make more informed choices. Keep reading to learn what’s really happening beneath the surface and how you can improve skin health without guesswork.
