Azelaic Acid (3-20%)

Azelaic acid is usually applied to the face, and can also be used on the neck and under-eye area when paired with a moisturiser. These areas tend to be more delicate, so a lower strength is generally recommended. Avoid applying it too close to the eyelids for comfort and safety.

Apply TWO pumps to clean, dry skin on the affected area(s) once daily at NIGHT. After applying, wash your hands and follow with a moisturiser to support comfort and hydration. Use an SPF 30 or higher every morning to keep your skin protected throughout treatment.

Monderma prescribes azelaic acid in strengths starting from 3% up to a maximum of 20%, in line with national guidelines.

The right strength for you depends on several factors, including whether you are treating acne, wrinkles, hyperpigmentation, or rosacea, your previous experience with lightening agents, and how your skin naturally responds. Starting too high or increasing too quickly can lead to unnecessary irritation.

Although some users gradually adjust their strength over time, many find that a consistent, lower strength provides the most comfortable experience and the most reliable long-term results.

You may begin to notice early visible improvements after the first week. For more sustained and meaningful results, nightly use for at least 12 weeks is recommended.

For most users, azelaic acid is a well-tolerated and reliable option for long-term skincare when used as directed.

Although azelaic acid is effective for a range of skin concerns, some users may experience mild side effects as their skin adjusts. These can include peeling, redness, or sensitivity, particularly during the first few weeks.

To minimise this, Monderma recommends beginning with a lower strength and pairing your treatment with a moisturiser to help maintain comfort as your skin adapts.

Azelaic acid is generally considered safe for use during pregnancy.

Azelaic acid is generally safe to use alongside most over-the-counter skincare products. If you are using any additional prescription skincare, you must inform Monderma so your azelaic acid formula can be reviewed for safe continued use.

Please also inform any healthcare professional or treatment provider about your prescription skincare. Certain procedures may require pausing azelaic acid before and after treatment to minimise sensitivity and reduce the risk of adverse reactions.
