WHAT IS AZELAIC ACID AND HOW DOES IT WORK?

Azelaic acid—a popular active ingredient in dermatology due to its wide range of therapeutic applications. And the global market for products containing azelaic acid is growing steadily, driven by rising demand for effective treatments for acne, rosacea, and hyperpigmentation. The effects of azelaic acid are correspondingly diverse. It can have antioxidant, keratolytic, and anti-inflammatory effects, as well as help even out skin tone in cases of redness. It is precisely this versatility that makes the active ingredient so popular. If you’re wondering what azelaic acid is or how it works on the skin, you’ll find a complete overview here—scientifically grounded and ideal for your daily routine.

Azelaic acid is a dicarboxylic acid and occurs naturally in wheat, barley, sunflower oil, and rye. However, a synthetic version may also be used in skin care products. The effects of azelaic acid on the skin are due to several properties:

It can inhibit the release of reactive oxygen species (ROS) and thus reduce oxidative stress in the skin.
Azelaic acid can help treat pimples because it can inhibit the growth of the bacterium Cutibacterium acnes, which is found in greater numbers on the skin in cases of pimples and acne. It has a keratolytic effect by regulating excessive skin keratinization.
It may have anti-inflammatory and antimelanogenic effects. Azelaic acid can inhibit melanin production through several mechanisms—such as by inhibiting tyrosinase and regulating overactive melanocytes. Therefore, it can be used to treat hyperpigmentation conditions such as melasma and post-inflammatory hyperpigmentation (PIH).
Azelaic acid can modulate inflammatory signaling pathways and reduce the production of pro-inflammatory cytokines—which supports its use in inflammatory skin conditions such as rosacea and acne.

It is precisely this combination that makes it an active ingredient suitable for use on oily and blemish-prone skin as well as on sensitive skin and uneven complexions. Unlike many other acids, it does not increase the skin’s sensitivity to light and can therefore be used daily, provided it is well tolerated.

Are you wondering what percentage of azelaic acid is effective? At concentrations of up to 10%, you may see results that can be particularly helpful for skin imperfections—especially if you have troubled skin. Higher concentrations of 15–20% require a prescription and are used in dermatology to treat skin conditions such as acne and rosacea.

AZELAIC ACID FOR VARIOUS SKIN NEEDS

Azelaic acid is particularly well-suited for blemished or acne-prone skin because it can soothe the skin, reduce the appearance of pores, and inhibit the growth of acne-causing bacteria. It is gentler on the skin than salicylic acid or retinoids, and azelaic acid also has a positive effect on pigmentation spots, acne scars, and melasma.

For skin prone to rosacea, anti-inflammatory and soothing effects play a key role. Azelaic acid can reduce redness, support the skin barrier, and help regulate keratinization (hyperkeratosis)—thereby helping to address blemishes and an uneven complexion.

Does azelaic acid also help with wrinkles? No, not directly, but in the context of well-aging, it can be beneficial because it offers antioxidant protection, has anti-inflammatory effects, and can support cell renewal. This makes it an exciting active ingredient for anyone looking for a gentle complement to retinoids and peptides.

HOW TO USE IT: HOW TO INCORPORATE AZELAIC ACID INTO YOUR SKINCARE ROUTINE

Azelaic acid is easy to incorporate into your daily routine. It can be applied in the morning or evening; however, if you have sensitive skin, it’s recommended to start slowly and limit use to two to three evenings a week before increasing the frequency. This is because, immediately after application, azelaic acid can cause a tingling or itching sensation (paresthesia) that lasts about 10–20 minutes. During the day, it’s essential to apply sunscreen afterward to protect the skin.

There are several products containing azelaic acid, ranging from serums to creams to masks. They pair exceptionally well with niacinamide, ceramides, and peptides, while combinations with highly concentrated AHAs/BHAs or retinoids should be introduced gradually. The Barrier Boost CPA Barrier Cream, for example, is a cream containing azelaic acid that strengthens the skin barrier and provides moisture.

WHY AZELAIC ACID IS A TRUE SKINCARE MULTITASKER

Azelaic acid is an active ingredient that addresses multiple skin concerns at once—even at low concentrations. It is suitable for blemish-prone skin, hyperpigmentation, skin prone to rosacea, sensitive skin, and early signs of skin aging. The effect always depends on the concentration, which makes the active ingredient versatile: Even at low concentrations, azelaic acid can have antioxidant, clarifying, and anti-inflammatory effects. For skin conditions, concentrations of 15 percent or higher are medically necessary.

KEY TAKEAWAYS

Azelaic acid is a versatile active ingredient that can help address a variety of skin concerns—from breakouts and dark spots to redness and sensitivity. Even low concentrations have antioxidant effects, while higher concentrations can be particularly effective in treating breakouts or hyperpigmentation. With the right skincare routine and daily sun protection, azelaic acid can help achieve a more balanced and even complexion over the long term.
