Method for characterizing the oxidative stress protective capacity of an antioxidative substance

A method for characterizing an oxidative stress protective capacity, relative to human skin, of a first antioxidative substance, the method comprising:

• providing a first result based on a performance of the first antioxidative substance in a first antioxidative efficacy test, the first antioxidative efficacy test measuring a first parameter associated with oxidative stress;
• assigning, based on the first result, a first score indicative of an oxidative stress protective capacity, relative to human skin, of the first antioxidative substance;
• providing a second result based on a performance of the first antioxidative substance in a second antioxidative efficacy test, the second antioxidative efficacy test measuring a second parameter associated with oxidative stress;
• assigning, based on the second result, a second score indicative of the oxidative stress protective capacity, relative to human skin, of the first antioxidative substance;
• and
• combining the first and second scores so as to provide a total score characterizing the oxidative stress protective capacity, relative to human skin, of the first antioxidative substance.
