What is the function of antioxidants in skincare?

Antioxidants play a crucial role in skincare primarily by protecting the skin against free radicals. Free radicals are unstable molecules that can cause oxidative stress, leading to cellular damage, accelerated aging, and various skin conditions. By neutralizing these free radicals, antioxidants help to mitigate their harmful effects, contributing to healthier and more resilient skin. Common antioxidants used in skincare include vitamins C and E, green tea extract, and coenzyme Q10, all of which collectively work to improve the skin’s appearance and function by reducing signs of aging and promoting a more radiant complexion.

The other options, while relevant to skincare, do not accurately reflect the primary function of antioxidants. Soothing sensitive skin is often more closely associated with calming ingredients rather than the antioxidant action. Healing wounds typically involves ingredients that support skin regeneration, which is different from the protective role of antioxidants. Enhancing exfoliation involves agents that promote cell turnover, such as alpha and beta hydroxy acids, rather than antioxidant properties.
