Topical antioxidants are one of the three daily essential skin care products that everybody should be using. The other two are sunscreens and exfoliants. But as crazy as this sounds, unless you put your topical antioxidants on at nighttime, they can’t work. Let me explain why. All antioxidants work by absorbing and neutralizing dangerous high-energy compounds such as free radicals which form inside your cells including your skin cells. When the topical antioxidant works, it acts like a sponge for the bad energy and absorbs the bad energy and it gets destroyed, but that way it prevents the bad energy from harming your cell. Ultraviolet light from the sun is just one of many different sources or causes of high-energy free radicals. They also form inside your cells for many other different reasons. So if you put your topical antioxidant on during the day, it’s going to do its job of acting like a sponge, it’s going to absorb some of the ultraviolet light from the sun, just the way sunscreens do; it’s going to help to protect you. But don’t forget, the antioxidant gets destroyed, but where you really need your topical antioxidant is inside your cell. That’s where you need it to protect you from the free radicals. So the only way that you can get the topical antioxidant into your cell is to put it on your skin when there’s no sunlight to destroy it. So therefore, you have to put your topical antioxidant on at nighttime so that it can be absorbed into your cells and be ready the next day to help protect you from free radicals and other forms of bad energy.
