What hormone plays a crucial role in the production of collagen?

  1. Testosterone

  2. Progesterone

  3. Estrogen

  4. Cortisol

The correct answer is: Estrogen

Estrogen plays a crucial role in the production of collagen, which is an essential protein that helps maintain the skin's structure and elasticity. This hormone is known to enhance the synthesis of collagen by stimulating fibroblasts, the cells responsible for producing it. The presence of estrogen contributes to the overall health and appearance of the skin, as it helps maintain skin thickness and moisture levels. Declines in estrogen levels, especially during menopause, can lead to a decrease in collagen production, resulting in signs of aging such as sagging skin and wrinkles. Understanding the impact of estrogen on collagen synthesis is vital for estheticians, as it informs treatments and products aimed at improving skin health and combating signs of aging.
