Antioxidants and Age Spots


Brown spots on the skin? Living under a star has its consequences! What you are actually seeing is “free radical” damage from the sun’s UV rays, also known as photoaging or sun damage. Compare this to slicing an apple and seeing it turn brown. To help these spots disappear there are many topical “antioxidant” skin care products available to repair the damage.

But, what actually are “free radicals” and what is so great about “antioxidants”? For a simplified explanation, see below:

Free radicals are unstable oxygen molecules that have lost an electron (remember science class…) and steal another one from nearby healthy molecules. For our bodies, this sets off a “free radical chain reaction” turning healthy cells into diseased ones and even altering DNA, causing mutated cells (cancer).  See the photo at the end of this article.. This process is called oxidation, and can be seen everyday when a slice of apple turns brown or metal rusts, or you get a brown/sun spot on your skin.

Because our bodies utilize oxygen, free radicals are produced as natural bi-products of metabolism. But, they also exist in our environment from pollution, sunlight, radiation, drugs, pesticides, fried foods, alcohol, and tobacco smoke, just to name a few. So, what can we do about free radicals? The answer is “antioxidants”!

Antioxidants seek out free radicals and replaces the missing electron without becoming a free radical itself! Our body makes it’s own antioxidants from the food we eat, but looses this ability as we age. Therefore, it is a good idea to eat foods with a high antioxidant content, take dietary supplements and use skin care products containing antioxidants.
