Have you've ever cut an apple in half and wondered why it goes brown so quickly? Well, you're watching oxidative stress at work. You are seeing a chain reaction of free radicals that causes stress on the apples cells which it cannot defend.  

Free radials are the enemy of healthy skin. Free radicals are unstable atoms that can damage cells, accelerating ageing and causing illnesses. But all is not lost; a healthy diet, plenty of water and good quality anti-oxidant skincare products can arrest and even reverse free radical damage.
