The genesis of a free radical externally is a bit scientific, however Fort Lauderdale, FL dermatologist Dr. Matthew Elias walks us by the method slowly.

“The skin is made up of lots and lots of molecules that all coexist together in a steady, peaceful way. Unfortunately sometimes that balance gets thrown off, typically due to inflammatory inducing processes like sunlight, smoking, pollution, stress, etc., and the skin is no longer in harmony,” explains Dr. Elias. “If any of the molecules in the skin get knocked out of whack due to inflammation they essentially lose an electron, and that is the ‘free radical’ that then scavenges around looking to steal that electron back from another molecule.” This then leads to a cascading occasion the place every molecule will strive to steal from the subsequent, which in the end leads to free radical injury and pores and skin that seems broken.
