What Is Azelaic Acid and What Does It Treat
Azelaic acid is a natural substance that comes from grains like wheat, rye, and barley. It also exists in small amounts in human skin. This compound belongs to a group called dicarboxylic acids and has a chemical formula of HOOC(CH2)7COOH. People use it in skincare products because it fights bacteria and helps with common skin problems.
In skincare, azelaic acid works in several ways. It gently exfoliates the skin to unclog pores and smooth out rough texture. It also fades dark spots from acne and evens out skin tone. Plus, it calms redness and makes skin less sensitive over time. These effects make it popular for daily use in creams, serums, and suspensions.
One main thing azelaic acid treats is acne. It clears congestion, reduces breakouts, and prevents new ones by killing acne-causing bacteria. You might see more pimples at first as it brings hidden ones to the surface, but this fades with continued use.
It also helps with rosacea, a condition that causes redness and irritation on the face. Azelaic acid soothes inflamed skin and builds tolerance to triggers. For perioral dermatitis or reactive skin, it reduces sensitivity and promotes balance.
Beyond that, azelaic acid brightens dull skin and improves uneven tone. It acts as an antioxidant to protect skin and is gentle enough for all skin types. Products often contain 10 percent azelaic acid, like suspensions that feel creamy when applied.
To use it, start slow. Apply a thin layer every other day on clean skin, then increase to daily as your skin adjusts. Wait 10 minutes before adding moisturizer or sunscreen. It pairs well with ingredients like retinol, niacinamide, and vitamin C. Always patch test first on your arm to check for irritation.
