Why are antioxidants commonly included in skincare products?

To provide color to the product
To protect the skin from environmental damage
To emulsify other ingredients
To enhance the texture of products

The correct answer is: To protect the skin from environmental damage

Antioxidants are commonly included in skincare products primarily for their ability to protect the skin from environmental damage. They play a critical role in neutralizing free radicals—unstable molecules that can damage cells and contribute to skin aging, including wrinkles, fine lines, and pigment changes. By mitigating the effects of oxidative stress caused by factors like pollution, UV radiation, and other environmental aggressors, antioxidants help maintain skin health and appearance. While other functions are important in skincare formulation, they do not pertain to the core function of antioxidants. For instance, coloring the product, emulsifying ingredients, and enhancing texture are roles fulfilled by other components or additives in skincare formulations, but they do not address the protective qualities that antioxidants uniquely provide.
