Azelaic Acid has migrated from medicinal topical applications for acne and rosacea to mainstream skin care due to the fact that it is so effective, yet so mild, with virtually no side effects. Any medicinal ingredient needs to be extremely consistent, hence the fact that Azelaic Acid is mostly bio-engineered to deliver just this.

Reduce acne and clear pores of bacteria
The treatment of acne, acne-prone and clog-prone skin involves several basic steps. The first step is daily follicular exfoliation. The basis of this step is to use ingredients like enzymes, alpha hydroxy acids or keratolytics to help the inside of the follicle to exfoliate, breaking loose cell buildup and solidified sebum, loosening clogged pores and drying visible lesions.
Azelaic Acid is a keratolytic (like Vitamin A) and its real value lies in the breakup of microcomedones (small impactions formed by cells that have built up on the inside of the follicle wall – think blackheads, whiteheads) that already exist. It also functions to keep hyperkeratosis (btw, hyperkeratosis is hereditary, the reason why you find acne running in a family) from accumulating, to form new microcomedones.
If you want to know more about exactly how a keratolytic helps keep your skin clear, read my blog on another potent keratolytic, Vitamin A, (here). Keep in mind Azelaic Acid is not a retinoid but both Vitamin A & Azelaic Acid are keratolytics.
I guess you now may want to know what the difference is between Vitamin A and Azelaic Acid.
