Ácido azelaico

About azelaic acid

Acne is the common cause of spots. Most people with acne are aged between 12 and 25 years, but some older and younger people are affected too. Small sebaceous glands lie just under your skin surface and make an oil (sebum) that keeps your skin supple and smooth. Tiny pores on your skin allow the sebum to come on to the surface of your skin. In acne, some of these pores become blocked, causing small pimples, blackheads and whiteheads. Azelaic acid skin cream and gel mainly work by unplugging blocked pores

Azelaic acid is also used for rosácea in adults. Rosacea is a skin condition that usually affects parts of your face such as your nose, cheeks and forehead. It is a condition that can often cause spots.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using azelaic acid it is important that your doctor knows:

• If you are taking any medicines or using any other skin preparations. This includes any which are available to buy without a prescription, as well as herbal and complementary medicines.

• If you have ever had an allergic reaction to a medicine or skin product.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about azelaic acid and will provide you with a full list of the side-effects which you could experience from using it.

• It is usually recommended that you use azelaic acid twice each day, in the morning and the evening. Before you apply the treatment, wash the area with soap and water and gently dry it with a towel. Then apply the cream/gel and rub it in gently. If your skin is particularly sensitive, you can apply the preparation just once a day for a few days before increasing it to twice a day.

• As you apply the cream/gel, try to avoid getting it on the sensitive areas of your skin in or around your nostrils, your eyes and your mouth. Do not apply it to any areas of skin which are irritated or sore.

• It is recommended that you use a mild soap and lukewarm water to wash with. Always dry the area gently with a towel before applying the treatment.

• Continue with the treatment for at least a month if you have acne (or two months for rosacea) before deciding if it is working for you or not. The most common reason for treatment failure is giving up too soon. If, however, your skin has not improved after this time then make an appointment to speak with your doctor who will advise you about other suitable preparations to try.
  

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with preparations containing azelaic acid. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine but speak with your doctor or pharmacist if any of the following continue or become troublesome.
