What would it be if all collagen were removed?

If all collagen were removed from the body, it would lead to severe structural instability in various tissues, including skin, bones, cartilage, and blood vessels. The skin would become saggy and lose elasticity, leading to wrinkles and increased susceptibility to injury. Joints would suffer from reduced cushioning, resulting in pain and impaired movement. Overall, the structural integrity of many organs and systems would be compromised, drastically affecting health and quality of life.
