One of the main causes of premature aging of the skin is the result of free radical damage, which occurs due many factors such as sunlight and pollutants. Free radicals are unstable oxygen molecules with only one electron that must take electrons from other molecules in order to re-stabilize. To do this, a free radical will attack a healthy cell and take an electron which causes those cells to decay. This deterioration of cells leads to signs of aging, such as wrinkles and hyperpigmentation.
A powerful way to fight and protect against these damaging free radicals is by using products with antioxidants. Antioxidants are chemicals which neutralize these destructive free radicals to protect the skin from damage.
