This is because of the fact that it inhibits the enzyme that melanin requires known as tyrosinase

Free radicals play critical role in generating oxidative stress, which oxidizes dopamine to dopamine quinone and superoxide anion and decreases the NADPH and dopamine metabolized by MOA that produces the 3,4-dihydroxyphenylacetaldehyde, ammonia, and H 2 O 2 , which in turn interacts with Fe ++ to generates the OH free radicals that kill neurons in PD [61, 62]
