Everything You Need to Know About Azelaic Acid 4: Benefits, Uses, and Side Effects

Azelaic acid is a naturally occurring acid that is used in a variety of skincare products. It is known for its ability to treat and prevent acne, reduce hyperpigmentation, and improve skin texture. One of the most popular strengths of this acid is azelaic acid 4, which is commonly used in over-the-counter products.

Azelaic acid 4 is a topical medication that is often recommended by dermatologists as an effective treatment for acne. It works by reducing the growth of acne-causing bacteria on the skin and by decreasing inflammation. The acid is also known for its ability to unclog pores and reduce the production of sebum, which can lead to fewer breakouts.

In addition to its acne-fighting properties, azelaic acid 4 is also a powerful tool for reducing hyperpigmentation. Hyperpigmentation can be caused by a variety of factors, such as sun damage or hormonal changes, and can result in dark spots or uneven skin tone. Azelaic acid 4 works by decreasing the production of melanin in the skin, which leads to a reduction in the appearance of dark spots.

There are several products on the market that contain azelaic acid 4 as the active ingredient. The Ordinary’s Azelaic Acid Suspension 10% is a popular choice, as it contains a higher concentration of the acid. Other products, such as Paula’s Choice 10% Azelaic Acid Booster and Garden of Wisdom Azelaic Acid Serum 8% with Niacinamide, also contain azelaic acid 4 and are highly rated by users.

It’s important to note that while azelaic acid 4 is generally well-tolerated by most skin types, some people may experience side effects such as dryness, redness, or itching. It’s always a good idea to do a patch test before using any new skincare product, especially one with an active ingredient like azelaic acid.

Overall, azelaic acid 4 is a powerful skincare ingredient that can help to treat and prevent acne, as well as reduce hyperpigmentation. It’s available in many different products, and can be a great addition to any skincare routine.
