What is Azelaic Acid (AZA)?
It is a saturated dicarboxylic acid that exists as a white powder found in wheat, rye, and barley. It is an organic compound and is also a precursor to diverse industrial products including polymers and plasticizers, as well as being a component of a number of hair and skin conditioners. Even though it is initially organic or biologic, it is industrially produced by the ozonolysis of oleic acid. [1]

What is odd is that when industrially produced one of the side products is nonanoic acid which "is produced naturally by Malassezia furfur (also known as Pityrosporum ovale), a yeast that lives on normal skin. The bacterial degradation of nonanoic acid gives azelaic acid." [1]

Brand Names for Rosacea Treatment

Finacea (USA) and Azelex (Europe) are two brand name prescription azelaic acid formulas that rosaceans are reporting works to control rosacea. Finacea 15% comes in a gel or a foam is made by Leo Pharma. Azelex 20% cream is made by Allergan who was bought by AbbVie (Allergan Savings Card).  According to OptumRx "Sandoz launched an authorized generic version" which is a gel and there are other manufacturers as well. [2] Skinoren, made by Bayer, is Azelaic Acid 20% used to treat acne. [4]

How Does It Work?
"Azelaic acid is in a class of medications called dicarboxylic acids. It works to treat rosacea by decreasing the swelling and redness of the skin. It works to treat acne by killing the bacteria that infect pores and by decreasing production of keratin, a natural substance that can lead to the development of acne." [3] 

"For acne, it works by killing the bacteria that cause acne and by keeping the skin pores clean." [5]

"Azelaic acid is a naturally occurring acid found in grains such as barley, wheat, and rye. It has antimicrobial and anti-inflammatory properties, which make it effective in the treatment of skin conditions like acne and rosacea. The acid can prevent future outbreaks and clean bacteria from your pores that causes acne." [6]

"It can help in both acne vulgaris and acne rosacea as an antimicrobial, antiinflammatory, and comedolytic. It can also be used for postinflammatory hyperpigmentation." [7]

"Our results indicated a potential role for azelaic acid in the protection of bulge cells from UVB damage and its combination with minoxidil may activate hair growth through overexpression of Shh protein." [9]

AZA Nanocrystal Suspension
A "a topical nanocrystal AZA-loaded hydrogels composed of Pluronic® F127 and hyaluronic acid mixture that are able to deliver AZA into the stratum corneum and deeper skin layers" has been studied in one paper that concluded that this formulation "possessed the rheological and drug delivery properties desirable for an in situ gelling platform for dermal application." [8]

Does it Work?
"Head-to-head trials show that azelaic acid and ivermectin might be slightly better than metronidazole." [10]

Clinical Papers

“Results of this study demonstrated a significantly greater potential for irritation from azelaic acid compared with metronidazole gel.” [275]
With this report done in August 2006:

“Azelaic acid in 20% cream and 15% gel formulations appears to be effective in the treatment of papulopustular rosacea, particularly in regard to decreases in mean inflammatory lesion count and erythema severity. Compared with metronidazole, azelaic acid appears to be an equally effective, if not better, treatment option.” [276]

However, some rosaceans may report irritation with azelaic acid while others report it is effective in controlling rosacea. Azelaic acid appears to be an accepted treatment so you should be aware of its use in rosacea.

“Data pooled from three between-patient trials showed a clear improvement in the azelaic acid group.” [277]

“Azelaic acid (AzA) initially was released in a 20% cream formulation, which has been shown to be effective in the treatment of mild to moderate rosacea. Recently, a 15% gel formulation was developed that vastly improved the delivery of AzA and has been proven by multiple studies to be effective in the treatment of rosacea. We present studies that examine both of these formulations, first in comparison with their vehicles and then in contrast with other well-accepted topical treatments of rosacea, such as metronidazole cream and gel.” [278]

It has been a few years since I had health insurance to cover Finacea, but I did use it for several months. For me it helped mildly and caused no irritation, which I find odd because my skin is quite sensitive to most things. I also do not have any negative effects with the Metrogel that I am kind of stuck with until I am covered by insurance. I think my results were better overall with the Finacea, however there was no dramatic results.

I am completely unable to use any moisturizers or cosmetics from regular store shelves, so I wonder why my skin tolerates Finacea so well when others have issues? I know every body is a little different in its sensitivities, like taking the antibiotics makes my nail beds lift, however for a prescription preparation designed for people with highly sensitive skin, it is distressing that it could make some cases worse.

finacea caused my mild case to be quite severe after one weeks use.

why are there no current members nor posts?

That is the question. Over 1300 members and hardly anyone posts. Maybe if we offered a RRDi tee shirt for each post there would be motivation to post?  You would think that these members would at least post once out of a volunteer spirit? I just got a Rx for the azeliac gel and foam versions and they should arrive next week in the mail. I will be posting my findings using these two on my face and scalp in my rosacea blog
