Pollution from air and sunlight has adverse effects on human health, particularly skin\nhealth. It creates oxidative stress, which results in skin diseases, including skin cancer and aging.\nDifferent types of antioxidants are used as preventative actives in skin-care products. However, they\nhave some limitations as they also scavenge oxygen. Recently, spin traps are being explored to trap\nfree radicals before these radicals generating more free radicals (cascading effect) and not the oxygen\nmolecules. However, not all spin traps can be used in the topical cosmetic skin-care products due to\ntheir toxicity and regulatory issues. The present review focuses on the different pathways of reactive\noxygen species (ROS) generation due to pollution and the potential use of spin traps in anti-pollution\ncosmetics to control ROS.
