Here at MDC, we would love to think that we have all the answers for you. However, there are certain issues that require the insight of a pro. Today we asked Boston-based dermatologist Dr. Emmy Graber to talk about a skincare issue that is always talked about but never quite explained: free radicals. Take it away Doc!
Absolutely everything in the world, from human beings to the air around us, is made of molecules. Molecules are made of atoms and atoms are made of pairs of electrons. When an atom is missing an electron, it is defined as a free radical. Free radicals can damage the skin by trying to grab an extra electron from atoms in the skin. When atoms are taken away from molecules in the skin, it causes damage to our skin’s DNA that can speed along skin aging. This is called the free radical theory of aging. This little science lesson probably raises the question: So, what does this mean for me and my skin? Let me give you a guide on how to better understand how free radicals work and how you can keep them from affecting your complexion.
Where Are Free Radicals?
Free radicals can be created from pollution such as smog, dust and cigarette smoke, as well as our good friend the sun.
What Does Free Radical Damage Look Like?
Skin damage done by free radicals may appear in several forms. Signs of damage ranges from changes in skin color (brown spots and broken blood vessels) and weakened skin that looks loose and saggy as a result of damaged elastic fibers. Free radicals can also break down the skin’s collagen and create wrinkles.
How Can I Stop Free Radicals From Hurting My Skin?
Antioxidants are compounds that can donate an electron to a free radical so that the free radical doesn’t have to take the electron from the skin’s atoms. Antioxidants include vitamin A, vitamin C and vitamin E and can be consumed via food and liquids (such as tomatoes, grapes and green tea) or applied topically. There’s a wide variety of creams, serums and lotions on the market containing antioxidants to help you fight skin damage.
