Acne is one of the most common and widely spread chronic skin disorders affecting millions of people around the globe. In the United States alone, it affects 17 million people every year. It affects people irrespective of their race, gender or age though it is more common in women than in men. However, it acquires a more severe form in men as per a survey.

The symptoms of acne include the breakout of pimples, whiteheads and blackheads along with inflammation and redness or scarring of the skin. At times these inflammations reach deep down under the skin developing cysts and nodules and causing a more severe form of cystic or nodular acne respectively.

The primary cause of acne breakout is the rise in the level of androgens. Higher androgen level induces the sebaceous glands to produce more sebum. Sebum is the oil like substance secreted by the sebaceous glands that are used to moisturize the hair follicles and surface of the skin.

However, its overproduction along with the accumulation of dead skin cells on the surface which leads to clogging of the skin pores prevents the sebum from coming out as it gets trapped under the surface of the skin creating an environment congenial to the growth of microbes.

It is these microbes that cause acne breakouts. This is the main reason why acne breakouts usually occur during or after puberty and it may or may not persist into the adult life of these people. According to a survey, at any one point in time approximately 85% to 90% teenagers face the problem of acne breakouts.

There are also other factors which can contribute towards the frequency and intensity of these breakouts which includes exposure to local pollution, naturally occurring oily skin and stress. Persisting acne often causes psychological morbidity resulting in anxiety, depression and stress.

A lot of methods and medications have been introduced with time which ranges from anti biotic to various herbal and home remedies. This article shall discuss the effectiveness of Azelaic acid in the treatment of acne along with its various benefits and side effects.

What is Azelaic Acid

Azelaic acid is basically an organic compound which exists as a white powder in form of saturated dicarboxylic acid. It is naturally found in wheat, rice and barley and is used in a number of hair and skin conditioners.

This medication is used for the treatment of comedonal or inflammatory acne. It is a form of dicarboxyl acid and kills the acne-causing bacteria thereby unclogging the pores that they otherwise keep occupied, to trap the excess sebum.

It also tends to inhibit the manufacture of keratin that would otherwise support the growth and survival of these bacteria and microbes.

It is used for correcting a number of skin conditions like rosacea, acne, skin pigmentation, melasma, post inflammatory hyper-pigmentation. Azelaic acid further facilitates a reduction in the production of melanin, as it also tends to function as a tyrosinase inhibitor.

How Azelaic Acid can Help in Acne Treatment

How is Azelaic Acid used to Treat Acne?

Azelaic acid has been a widely popular topical treatment for acne. It is often combined with oral antibiotic or hormonal therapy.

Azelaic acid tends to exhibit antibacterial properties which help in killing and thereby reducing the P.acne bacteria and inhibit their growth in the follicle. It also shows keradolytic and comedolytic properties which reduce the disordered growth of skin cells lining the follicle.

It further functions as an antioxidant reducing the oxidative stress due to the presence of free radicals which further helps in the reduction of inflammation.

Application

Before it is applied to the affected area, the area should be washed and pat dry. After this, a thin layer can be applied and massaged gently. In order to get maximum benefits, it should be used regularly. Improvement is seen mostly only after a month of using it. No bandage should be placed over the cream unless otherwise directed by the doctor.

Dosage

This can be applied twice daily usually in the morning and evening if not otherwise directed by the doctor concerned. In order to facilitate regularity, it is usually advised that you apply it at the same time every day.

Any contact with the eyes, ears or mucous membranes should be avoided as it is only meant for external use. Large amount of this medication should not be applied as it would only increase the risks of side effects and will not contribute towards speeding up the healing process in any way.
