Free Radicals: What They Are & Why They Are Bad for Your Skin

Here at makeup.com, we 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. But when an atom is missing an electron, that’s when we talk of free radicals.

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: And 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. They range from changes in skin color (brown spots and broken blood vessels) to 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 Harming My Skin?

Your answer to free radicals are antioxidants! They 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.

Product Recommendations: Skinceuticals C E Ferulic Acid; Garnier Moisture Rescue Refreshing Gel-Cream; and Biotherm Skin Best Day Cream SPF15 Normal Skin.
