The antioxidant efficacy test for skin assesses the ability of skincare products to provide protection against oxidative stress by measuring their capacity to neutralize free radicals and reduce oxidative damage.
Positive results indicate the product’s effectiveness in supporting skin health and defending against environmental aggressors.
DPPH exhibits a strong purple color in its radical state. However, upon receiving electrons or hydrogen from the sample, it undergoes a conversion to a non-radical state, resulting in a decrease in absorbance to yellow.
This transition to 2,2-Diphenyl-1-picrylhydrazine (DPPH-H) serves as an antioxidant indicator, allowing for the evaluation of the sample’s antioxidant capacity.
