All cells in your body are subject to oxidative stress. That is one very fancy term for the fact that all of these cells have these high energy particles and they have a special name called “Free Radicals”. These high energy particles unpredictably discharge all of their energy and throw it at the cells DNA, at the elastic tissue, at the collagen and cause damage. The purpose and rule of antioxidants especially topical antioxidants is to absorb that bad energy before it can hit the DNA and the collagen and so on, absorb it and protect the important parts of your skin and your body.
All cells in your body get different sources of these high energy free radicals, but the skin gets more than any other, because the skin gets ultraviolet light which no other organ in the body gets, and even if you use your sunscreen like the way I showed you and even if you choose the sunscreen that I told you, some how sunscreens are not 100% effective so some of this damaging ultraviolet light gets through, gets around the sunscreen and forms more of these high energy dangerous free radicals in the skin. So the real value of topical antioxidants is to help protect the skin, help protect your DNA so that you do not get cancer, to help protect the collagen and elastic tissue so that you do not get wrinkles and sagging skin from these high energy dangerous free radical particles and selflessly absorb that energy, get destroyed and protect your skin. That is why I tell you to use your topical antioxidants at night.
