A type of acid known as a dicarboxylic acid derived from grains that offers numerous benefits when applied to skin. For example, it’s a gentle leave-on exfoliant which helps unclog pores and refine skin texture. Azelaic acid also significantly lessens factors in skin that lead to redness and bumps. Azelaic acid is also an antioxidant.
Research has shown azelaic acid can significantly diminish blemishes, help fade the appearance of post-acne red marks and other discolorations, and reduce the kind of skin sensitivity that leads to redness.
Although azelaic acid can be derived from grains like barley, wheat, and rye, its lab-engineered form is typically used in skincare products because of its stability and effectiveness. Because of this, azelaic acid is considered a synthetic ingredient, but this is a clear case where the synthetic version outperforms the natural version, with no research indicating a risk to skin.
Azelaic acid is available in strengths of 10% or less over-the-counter, and in topical prescription products at concentrations between 15-20%.
