Description:
Azelaic acid is an organic compound with the formula (CH2)7(CO2H)2. This saturated dicarboxylic acid exists as a white powder. It is found in wheat, rye, and barley. It is a precursor to diverse industrial products including polymers, plasticizers, as well as being a component of a number of hair and skin conditioners.
Applications:
Azelaic acid is used to treat mild to moderate acne, both comedonal acne and inflammatory acne. It belongs to a class of medication called dicarboxylic acids. It works by killing acne bacteria that infect skin pores. It also decreases the production of keratin, which is a natural substance that promotes the growth of acne bacteria. Azelaic acid is also used as a topical gel treatment for rosacea, due to its ability to reduce inflammation. It clears the bumps and swelling caused by Rosacea.
The mechanism of action is thought to be through the inhibition of hyperactive protease activity that converts cathelicidin into the antimicrobial skin peptide LL-37. Azelaic acid has been used for treatment of skin pigmentation including melasma and post-inflammatory hyperpigmentation, particularly in those with darker skin types. It has been recommended as an alternative to hydroquinone (HQ). As a tyrosinase inhibitor, azelaic acid reduces synthesis of melanin.
Azelaic Acid is naturally antibacterial which makes it a great treatment for acne. When applied topically, it reduces the growth of bacteria in a follicle,helps to reduce inflammation and remove dead skin cells to prevent future acne breakouts. Azelaic Acid can be used on just about any skin type, including sensitive skin, as it has the ability to reduce inflammation. Anyone with rosacea, especially those with acne rosacea, will find it makes an excellent treatment for calming and soothing their inflamed skin.
