Indications of azelaic acid

  • Azelaic acid is commonly used to treat inflammatory condition such as acne.
  • It is often used successfully for the treatment for lentigines, PIH, melasma and rosacea (Policarpio and Lue, 2009).
  • Effective in treatment of hypermelanosis caused by various physical and chemical agents and factor. It is also effective in the treatment for other skin disorders characterized by abnormal proliferation of melanocytes.
  • It is also commonly used for skin whitening effectively.

The only problem of treatment with azelaic acid is that its therapeutic response is rather slow (Solano et al., 2006)


Mechanism of action

  • Study show that azelaic acid brings about skin whitening through its action as a melanin synthesis inhibitor. Azelaic acid is a rather weak competitive inhibitor of tyrosinase enzyme.
  • It is also shown to have an anti-proliferation and cytotoxic effect on pigment producing cell, the melanocytes (Pravez et al., 2007).
  • Azelaic acid is not able to induce depigmentation on normally pigmented skin, suggesting its selective anti-proliferation and cytotoxic action on abnormal melanocytes.
