The phonetic transcription of azelaic acid is /əˈziləɪk ˈæsɪd/, with the stress on the second syllable. The word is spelled with a 'z' and not an 's' because the root word in Greek begins with a zeta (ζ) and not a sigma (σ).
Azelaic acid is a naturally occurring organic compound with the molecular formula C9H16O4. It is a dicarboxylic acid that belongs to the family of carboxylic acids. This compound is widely used in the field of medicine and cosmetology due to its various beneficial properties.
In medicine, azelaic acid is primarily used for its antimicrobial and anti-inflammatory effects. It is commonly prescribed as a topical treatment for acne vulgaris, a common skin condition characterized by the presence of pimples, blackheads, and whiteheads.

In the field of cosmetology, azelaic acid is utilized for its ability to brighten the skin and improve its overall texture. It is often found in various skincare products such as creams, gels, and serums that aim to even out skin tone and reduce the appearance of blemishes. Furthermore, azelaic acid has been shown to possess antioxidant properties, which can help protect the skin from the damaging effects of free radicals and oxidative stress.
Overall, azelaic acid is a versatile compound that offers multiple benefits for the skin. Its antimicrobial, anti-inflammatory, and depigmenting properties make it an effective ingredient in the treatment of various dermatological conditions, while its brightening and antioxidant effects contribute to healthier and more radiant skin.
The word "azelaic acid" comes from its chemical structure and the source from which it was originally derived. The term "acid" refers to its classification as a carboxylic acid, which is a type of compound characterized by a carboxyl functional group (-COOH). "Azelaic" is derived from the Latin word "azela", which means "goat". This name was given because azelaic acid was initially isolated from products of the oxidation of oleic acid, which is a fatty acid found abundantly in goat tallow.
