Azelaic acid is a gentle skincare ingredient that helps reduce redness and fade acne marks. It comes from grains like wheat and barley, and works well for people with sensitive skin who deal with breakouts.
This acid fights acne in three main ways. First, it clears pores by breaking down dead skin cells that clog them. Second, it stops bacteria like Cutibacterium acnes from growing, which causes pimples. Third, it calms swelling and redness by lowering inflammation signals in the skin.[1][2][4]
For redness, azelaic acid soothes irritated areas quickly. It cuts down on cytokines, which are chemicals that make skin red and puffy. Users often see less flushing after a few weeks of use, especially on cheeks or around the nose.[1][3]
Acne marks, those dark spots left after pimples heal, also improve with azelaic acid. It blocks tyrosinase, an enzyme that makes pigment, so spots lighten over time. This makes it great for post-inflammatory hyperpigmentation without harsh bleaching.[2][3]
You can find azelaic acid in creams or gels at 10 to 20 percent strength. Start with a pea-sized amount at night after cleansing. It pairs well with moisturizers since it is mild and safe for daily use, even during pregnancy.[2]
Some people notice a slight tingle at first, but it fades as skin adjusts. Use sunscreen during the day because it can make skin a bit more sun-sensitive. Over time, it keeps follicles clear, cuts bacterial buildup, and stabilizes oil production to prevent new marks.[1]
