Additionally, retinol stimulates the production of collagen, a key protein that helps maintain skin elasticity and firmness. This further contributes to improving the skin’s overall texture and appearance. By addressing the underlying issues that contribute to an aged appearance—such as loss of moisture and structural integrity—retinol is essential in a skincare regimen focused on aging skin.
