Which of these does the body NOT replace naturally?

Collagen
Elastin
Skin cells
Blood cells

The correct answer is: Elastin

Elastin is a protein in the body that helps maintain the skin's elasticity and firmness. Unlike skin cells, which are constantly being shed and replaced, elastin is primarily produced during the growth phases of early development and in youth. As people age, the natural production of elastin significantly decreases, which is why the skin can start to lose its youthful firmness and elasticity, leading to sagging and wrinkles. In contrast, collagen continues to be produced throughout a person's life, although its production also decreases with age. Skin cells are constantly renewed as part of the skin's natural cycle, and blood cells regenerate regularly in the bone marrow. Therefore, the lack of natural replacement for elastin is what sets it apart from the other options listed.
