What is sagging skin a sign of?

Sagging skin is primarily a sign of poor elasticity. As the skin ages, it naturally loses elasticity due to a decrease in collagen and elastin production, which are essential proteins that provide structure and resilience to the skin. When these proteins degrade over time, the skin can lose its firmness and ability to bounce back after being stretched, resulting in a sagging appearance.

Poor elasticity can also be influenced by factors such as sun exposure, smoking, and environmental stressors, all of which can further degrade the structure of the skin. Maintaining healthy skin through hydration, nutrition, and appropriate skincare can help support elasticity, but once elasticity is compromised, sagging skin becomes more prominent.

The other options suggest conditions that do not directly relate to the loss of skin firmness. Overhydration can lead to a different set of skin issues, excessive collagen production typically results in thicker skin rather than sagging, and increased oil production is usually associated with acne or oily skin rather than elasticity or sagging.
