Azelaic Acid: Gently Treats Acne, Dark Spots, and Redness

There’s nothing the skin-care community loves more than a well-researched ingredient with multiple benefits. From vitamin C to niacinamide, multitasking heroes are the cost- and time-effective way to help to streamline our shelfies. Of late, azelaic acid, an often-overlooked dermatologist favourite, has been getting more recognition for its acne-busting, rosacea-calming properties, which is why we spoke to trusted experts to get intel on why azelaic acid is an ingredient worth getting to know.

What Is Azelaic Acid?

Hailed as the overachieving ingredient that can treat acne and rosacea, azelaic acid is a naturally occurring acid, according to consultant dermatologist Mary Sommerlad, MBBS, MRCP. “Azelaic acid belongs to a family of acids called dicarboxylid acid,” Dr Sommerlad told us. “It is derived from grains and wheat but can also be formulated synthetically in labs.” The lab-engineered version is most often used in skin care not only due its stability, but also so that it’s safe for those with a gluten intolerance.

What Does Azelaic Acid Do For Your Skin?

Like any good multitasker worth its weight in gold, “Azelaic acid is an extremely versatile ingredient that boasts numerous skin benefits,” said Nicolas Travis, founder of Allies of Skin and PSA.

Dr Sommerlad agreed, explaining that it was initially designed as an acne treatment. “It has anti-inflammatory and antibacterial qualities, which are great for acne-prone skin as it can help calm and reduce spots.” Those properties are what make azelaic acid an excellent choice for treating rosacea too. “Papulopustular rosacea is associated with red bumps and pus-filled blemishes, and regular use of azelaic acid helps to mitigate the associated redness and swelling with minimal risk of adverse side effects,” Dr Sommerlad added. Similar to other well-loved acids such as AHAs and BHAs, azelaic acid does have exfoliating properties, albeit much gentler and therefore far better tolerated by sensitive or compromised skins.

For those suffering with postinflammatory hyperpigmentation, azelaic acid can also help to fade stubborn marks. “It can improve hyperpigmentation by inhibiting tyrosinase, the enzyme crucial to the production of melanin,” Dr Sommerlad explained, adding that although azelaic acid tackles excessive melanin production, it doesn’t depigment the skin. “Azelaic acid is a great long-term treatment option for people with melasma, and at concentrations of 20 percent, it has been shown to be as effective as four-percent hydroquinone, which is known for having several side effects.”

If that wasn’t enough, it also acts as a powerful antioxidant to help counteract the effects of pollution on the skin.

Who Can Use Azelaic Acid?

Thankfully, azelaic acid is a largely well-tolerated ingredient, suitable for all skin types with few side effects. “Mild irritation such as burning, stinging, and redness can occur when using high concentrations,” said Petrina Nugawela, a specialist aesthetic practitioner and the founder of MBA Clinics. She added it may not mean that the product disagrees with you and rather that you need guidance with application and dosage.

There’s also good news for those who are pregnant or breastfeeding, as azelaic acid is one of the few topical acne- and rosacea-fighting ingredients that is widely regarded as safe. “It is not known to be harmful in pregnancy but the recommendation is to only use if the benefits outweigh potential risks,” explained Dr Sommerlad, who said dermatologists are generally happy to prescribe prescription-strength azelaic acid to those trying to conceive and throughout pregnancy. Nugawela added that while there is no known risk, you should always get confirmation from your doctor and midwife first before starting or continuing treatment.

How Do You Incorporate Azelaic Acid Into Your Skin-Care Routine?

Just like other acids, azelaic acid comes in multiple different strengths. “It can be purchased at concentrations of 10 percent over the counter, but concentrations at 15 percent and 20 percent, which may be more effective for moderate acne, melasma, and postinflammatory hyperpigmentation, are available on prescription,” said Dr Sommerlad.

Regardless of the strength, Dr Sommerlad said it can be used in both morning and evening routines. “Unlike other ingredients, it can be used morning and evening,” she said. “If using in the morning, apply after a vitamin C but before SPF.” Nugawela added that if using in the evening, apply a thin layer on clean, dry skin at least half an hour before bed. “Be mindful that if using a prescription-strength retinoid as well, limit azelaic acid to alternate days or in the morning only,” she said.

Although combining active ingredients can be a minefield, Travis said that azelaic acid plays well with other ingredients. “It’s a great ally and I like pairing it with ingredients that have antiblemish and brightening properties,” he explained. Dr Sommerlad added that not only does azelaic acid work very well with a number of ingredients, particularly retinoids, antioxidants, and liquid exfoliants, it can also increase the potency of their effects. “It is a real skin-care hero of mine but as always, when using active ingredients, gradually introduce your skin to azelaic acid, by applying it only a few times a week for the first week or two before building up,” she said.
