A deficiency in vitamin C can contribute to sagging skin. Vitamin C is crucial for the production of collagen, a protein that provides structure and elasticity to the skin. When vitamin C levels are low, collagen production decreases, leading to thinner, less elastic skin, which can appear saggy.
While vitamin C deficiency is a significant factor, it's important to remember that other factors can also cause sagging skin, including aging, genetics, weight loss, and sun exposure.
