What is the primary role of antioxidants in skin care?

The primary role of antioxidants in skin care is to protect the skin from free radicals and environmental damage. Free radicals are unstable molecules that can cause oxidative stress, leading to premature aging, inflammation, and the breakdown of collagen and elastin in the skin. Antioxidants neutralize these free radicals, effectively minimizing their harmful effects. This protective function helps maintain the skin's health, reduces signs of aging, and can even improve the overall appearance and vitality of the skin.

Other options, while they are important aspects of skincare, do not accurately describe the primary function of antioxidants. Enhancing skin color and texture typically involves other ingredients, such as exfoliants or skin brighteners, while hydration is primarily the role of moisturizers. Additionally, stimulating hair growth is unrelated to the skin and pertains to treatments aimed at the scalp or hair follicles.
