Comedonal acne, which may include both whiteheads and blackheads, can be a frustrating condition. It's most common in teenagers, but many adults get it too. Fortunately, numerous treatments are available to manage mild to moderate comedonal acne, including azelaic acid cream. You'll need a prescription from your doctor to obtain this product.
Azelaic Acid for Comedones
Whiteheads develop when excess oil and dead skin cells clog pores and also block the opening of pores. Blackheads also are clogged pores, but the pore surface remains open. Dermatologists call a blackhead an open comedo and a whitehead a closed comedo. When more than one occurs, the pimples are called comedones. Azelaic acid helps clear acne by killing and stopping the growth of skin bacteria that cause pimples and by reducing the production of keratin, a fibrous protein that can block pores along with excess oil.
Method
To use azelaic acid in the management of comedonal acne, begin by washing your skin with water and a mild soap or a cleansing lotion, then pat it dry. Avoid cleansing agents that contain alcohol, abrasives, astringents or peeling agents. Apply a thin layer of azelaic acid cream to the comedonal acne and gently rub it into the skin. Keep the medicine away from your eyes, lips, mouth and the inside of your nose. If you accidentally get azelaic acid in any of those areas, rinse thoroughly with water. Wash your hands with soap after you finish rubbing in the medication. You may apply makeup over azelaic acid cream after it dries, but don't cover it with any bandages or dressings.
Time Frame
Normally you apply azelaic acid once in the morning and again in the evening, but follow your doctor's instructions. It can take more than four weeks before the medicine achieves full results, so keep using it even if you don't see much improvement for awhile. In addition, if your acne begins clearing up quickly, don't stop using the treatment. That can cause the acne to return or become worse.
Side Effects
Azelaic acid can cause side effects, including redness, dryness, itching, peeling, burning and stinging. Consult your doctor if these effects are severe or do not go away over time. You might need to use the medicine less often or stop using it for a short time. The medicine could lighten skin color, particularly if you have a dark complexion. Talk to your doctor as soon as possible if this occurs. Also call your doctor if you develop a rash, which could be an allergic reaction to azelaic acid.
