Properties :

1.Antibacterial: it reduces the growth of bacteria in the follicle (Propionibacterium acnes and Staphylococcus epidermidis).
2.Keratolytic & comedolytic: it returns to normal the disordered growth of the skin cells, lining the follicle.
3.Scavenger of free radicals and reduces inflammation.
4.Reduces pigmentation: it is particularly useful for darker-skinned patients, who have melasma, or whose acne spots leave persistent brown marks known as actinic lentigenes. 
5.Non-toxic, and is well tolerated by most patients.

Azelaic acid does not result in bacterial resistance to antibiotics, reduction in sebum production, photosensitivity (easy sunburn), staining of skin or clothing, or bleaching of normal skin or clothing.Because 20% azelaic acid can be a skin irritant, it should be used only when prescribed by a physician.

Uses :

Azelaic acid is used to treat mild to moderate acne; i.e. both comedonal acne and inflammatory acne. It works in part by stopping the growth of skin bacteria that cause acne, and by keeping skin pores clear.
Azelaic acid is also used as a topical gel treatment for rosacea, due to its ability to reduce inflammation. In some cases, females have reported hair growth on face and neck.
Azelaic acid may be useful as a hair growth stimulant.
