The other day, I bought an expensive serum that promised to miraculously take years off my face by fighting free radicals. Was I entirely sure what these sinister-sounding enemies were and why I needed to invest in a product to fight them? No. Was I ready to fork over an absurd amount of cash to go to war with my fine lines? For sure.
But it did make me curious to learn more about the supposed culprits associated with my superficial concerns. What are free radicals anyway? I'd heard the term before (even outside the marketing for my new costly face lotion). Is my anti-aging cream the only way I need to protect myself or should I be more concerned about free radicals and far more serious health issues like cancer?
