Detailed answer

Caffeine consumption negatively affects skin elasticity because it can lead to increased breakdown of collagen and elastin, proteins that are crucial for maintaining skin's firmness and elasticity. Caffeine acts as a diuretic, which can lead to dehydration of the skin, making it appear dull and less supple. Additionally, caffeine may inhibit the production of hyaluronic acid, a substance that helps retain moisture in the skin, further contributing to loss of elasticity. To maintain or improve skin elasticity, it is advisable to limit caffeine consumption and focus on hydrating the skin with adequate water intake and skincare products that support collagen production.
