Sagging skin develops when collagen and elastin levels decline, reducing the skin’s ability to stay firm and tight. This can affect various areas, including the face, neck, arms, stomach, and legs, creating a less sculpted appearance. Gravity, weight fluctuations, and environmental damage contribute to the thinning and loosening of the skin, making it more noticeable over time. While this is a natural part of aging, noninvasive treatments can help tighten, tone, and lift the skin, restoring a more youthful contour.
