It appears that electrons in these molecules in our skin have lots of energy and can cause damage
to these thihngs like DNA and RNA, and has a detrimental effect on our skin.
Antioxidants are things that come along and absorb some of these electrons so they are not spinning around causing damage.
Antioxidants in terms of application--it can be applied topically or they can be taken by mouth.
Theoretically antioxidants should reduce the damage, and hence, the aging effects of the sun.
To this point in time, I think the evidence is still wanting in terms of, do they in reality provide benefit.
One of the issues is penetration--if you apply an antioxidant to the skin, it only sits very high in the skin
and most of the activity where you need antioxidants is deep in the living part of the epidermis and in the dermis itself.
While antioxidants such as the Vitamin C and Vitamin E are powerful antioxidants--do we know that
they work in the skin in a beneficial way? I think we have to wait and get evidence in the future about this.
