Azelaic acid is a naturally occurring dicarboxylic acid found in grains like wheat, rye, and barley. It is also produced by the Malassezia yeast that lives on our skin. Azelaic acid has been used for centuries to treat a variety of skin conditions, including acne, rosacea, and melasma.
One of azelaic acid primary uses is in the treatment of acne, where it works by reducing inflammation and the growth of acne-causing bacteria on the skin.
In addition to its anti-acne properties, azelaic acid has also been shown to have tyrosinase inhibiting properties, making it an effective ingredient for the treatment of hyperpigmentation. By reducing the production of melanin, azelaic acid can help to even out skin tone and reduce the appearance of dark spots.
Another benefit of azelaic acid is that it has antioxidant properties, which can help to protect the skin from environmental stressors and premature aging. It has also been shown to have anti-inflammatory properties, which can help to reduce redness and irritation in the skin.
Azelaic acid works by:
- Killing bacteria that cause acne
- Reducing inflammation
- Unclogging pores
- Lightening dark spots
- Improving skin texture
Azelaic acid is a safe and effective treatment for a variety of skin conditions. It is well-tolerated by most people, and it is less likely to cause irritation than other acne treatments, such as benzoyl peroxide and salicylic acid.
Azelaic acid is available over-the-counter (OTC) in concentrations of 10% and 20%. It is also available by prescription in concentrations of up to 45%.
When using azelaic acid, it is important to start with a low concentration and gradually increase the concentration as needed. It is also important to use a sunscreen with an SPF of 30 or higher every day, even on cloudy days.
Here are some additional tips for beauty professionals and estheticians who are using azelaic acid with their clients:
- Start with a low concentration of azelaic acid and gradually increase the concentration as needed.
- Use azelaic acid only as directed.
- Avoid using azelaic acid on open wounds or irritated skin.
- Use a sunscreen with an SPF of 30 or higher every day, even on cloudy days.
- Wear protective clothing when you are outdoors.
- Monitor your skin for any changes, such as redness, irritation, or blistering.
- If you experience any side effects, stop using azelaic acid and talk to your doctor or dermatologist.
Azelaic acid is generally considered to be safe to use during pregnancy, but it is always a good idea to consult with a healthcare provider before using any skincare products during pregnancy. While there is no evidence to suggest that azelaic acid is harmful to a developing fetus, it is still important to exercise caution and avoid any unnecessary risks. It may also be helpful to patch test any new products containing azelaic acid on a small area of skin before using them more widely, to check for any potential irritation or sensitivity.
