Azelaic acid is emerging as a significant ingredient in skincare, praised by beauty editors and dermatologists for its efficacy in treating acne and rosacea. The compound, naturally found in grains like wheat, barley, and rye, has been utilized in dermatology for decades.
Its properties include anti-inflammatory and antimicrobial effects, making it beneficial for calming redness associated with rosacea and treating acne. Azelaic acid also aids in the shedding of skin cells within pores, which can prevent the formation of blackheads and whiteheads. Furthermore, it plays a role in reducing hyperpigmentation by inhibiting tyrosinase, an enzyme involved in melanin production, thus helping to fade dark marks left by acne or inflammation.
Experts note that azelaic acid's benefits extend to a wide range of skin types. Unlike some other acids, it helps regulate inflammation, blemishes, and pigmentation without excessively drying or irritating the skin's surface. For those starting out, a concentration of 10 percent is often recommended, while higher strengths of 15 to 20 percent may be prescribed for more persistent issues.
However, for ongoing redness related to rosacea, consulting a professional is advised. While azelaic acid can help with the inflammatory aspects and associated redness, it does not address visible dilated blood vessels, known as telangiectasia, commonly seen in rosacea. Dermatologists suggest seeking a formal diagnosis if self-treatment yields no improvement.
Incorporating azelaic acid into a skincare routine can be straightforward, as it is compatible with other active ingredients like retinoids and vitamin C. It can be applied in the morning or evening, and some formulations can be used twice daily once the skin is accustomed to the product. Consistency is key, with noticeable improvements often appearing after about four weeks, though results are best evaluated over several months.
