Antioxidants are ingredients that can help the body and the skin eliminate or fight the effects of free radicals and prevent the oxidation.



What is oxidation and what are antioxidants?


Oxidation is the loss of electrons by a molecule, atom or ion. In other words, oxidation is the process of degradation caused by the light and oxygen. It can also mean the gain of oxygen, or the loss of hydrogen.
A free radical is an atom, molecule or ion that has unpaired electrons. In general, these unpaired electrons make free radicals highly chemically reactive towards other substances, or even towards themselves.
Free radicals have somehow lost an electron. They can be formed during normal functions such as when cells burn food for energy or even when the body is fighting off bacteria or viruses.  
Free radicals in general are not dangerous. But when our cells are exposed to pollution, radiation, cigarette smoke or certain chemicals, this process creates a larger quantity of free radicals in the body: a surplus of unbalanced cells looking to become balanced by scavenging for electrons.
They will actually “steal” electrons from balanced cells and set off a chain reaction of damage. If there are no electrons available, or if free radical production is in excess, damage occurs and creates an environment of oxidative stress.



Why are antioxidants used in skincare?

An antioxidant effectively inhibits the oxidation of other molecules, which means they don’t turn into free radicals. They are key ingredients in preventing skin ageing - not in treating wrinkles, because the damage has already been caused.  
Antioxidants can be oil-soluble, like Coenzyme Q10 and Vitamin  E or they can be water-soluble, such as ascorbic acid (Vitamin C), green tea, coffeeberry and resveratrol.  
LILIXIR Ageless Day Serum and LILIXIR Ageless Night Serum are packed full with antioxidants that will prevent the skin ageing. Beside that they create a film on the surface of the skin, blocking the water inside, enhancing the penetration.
