Azelaic acid is a natural acid that is derived from various grains like wheat and barley. It helps reduce acne by preventing skin cell buildup, killing p. acnes bacteria, and reducing inflammation4. This means it can help reduce all kinds of acne, from blackheads to pimples. Blackheads and whiteheads form when dead skin cells combine with sebum, the oil our skin naturally produces and get clogged in a pore. To get rid of this kind of acne, it helps to regulate your skin cell production and exfoliate your skin to remove excess dead skin cells. Azelaic acid is a great way to do both of these things, while also decreasing inflammation and killing bacteria. When the skin is inflamed, it swells slightly, causing the pores to constrict. This traps dead skin cells and sebum inside, leading to blackheads and whiteheads, and if bacteria get trapped as well, then pimples can also form.
Acne medications work by reducing oil production, speeding up skin cell turnover, fighting bacterial infection or reducing inflammation — which helps prevent scarring. With most prescription acne drugs, you may not see results for four to eight weeks, and your skin may get worse before it gets better. It can take many months or years for your acne to clear up completely.
