Azelaic acid is a naturally occurring dicarboxylic acid that treats acne and rosacea by reducing inflammation, normalizing skin cell turnover, and inhibiting bacterial growth. While its primary use is therapeutic, these mechanisms may also offer secondary benefits for skin appearance by addressing issues like post-inflammatory hyperpigmentation. Its impact on systemic healthspan is negligible.
Verdict
Excellent for treating acne and rosacea; minimal direct healthspan benefits.
