Which ingredient is commonly used in anti-aging skincare products?

Retinol is commonly used in anti-aging skincare products due to its ability to enhance cell turnover and stimulate collagen production. This vitamin A derivative helps to reduce the appearance of fine lines, wrinkles, and age spots, making skin look younger and more radiant. Additionally, retinol can improve skin texture and tone, contributing to a more youthful appearance. Its effectiveness in promoting skin renewal and reducing signs of aging has solidified its role as a staple ingredient in many anti-aging formulations.
