By inhibiting the activity of neutrophils, it inhibits the production of free radicals and serves as their binder.Thus, it has anti-aging properties.Azelaic acid has a bacteriostatic effect on Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis bacteria by blocking oxidoreductive mitochondrial enzymes and inhibiting the synthesis of DNA and bacterial cell proteins.By inhibiting 5α-reductase - the enzyme that catalyzes the reaction of testosterone becoming its active form - dihydrotestosterone - reduces lipogenesis, thus it has comedolytic properties.
