Breakouts, redness, dark spots, and uneven tone? Meet the multitasking skincare ingredient that's suddenly everywhere, even though dermatologists have been using it for decades.
Every few months, skincare introduces us to another must-have ingredient. Some deserve the hype. Others have us wondering whether we really need another serum.
Azelaic acid? This one's worth getting to know.
Once mostly found in prescription dermatology treatments, azelaic acid has become a buzzy ingredient in mainstream skincare. And unlike some fleeting trends, it has years of clinical research behind it.
Even better? It's one of the topical ingredients dermatologists commonly recommend during pregnancy.
Let's get into what it actually is, how it works, and why it deserves a place in the maternity skincare conversation.
First Things First: What Is Azelaic Acid?
Despite the name, azelaic acid isn't your typical exfoliating acid.
It's a naturally occurring compound called a dicarboxylic acid, found in grains such as wheat, barley, and rye. It's also produced naturally by certain yeasts.
In skincare, azelaic acid is valued for its antibacterial, anti-inflammatory, and pigment-regulating properties. Unlike glycolic acid, which primarily exfoliates the skin's surface, or salicylic acid, which helps clear clogged pores, azelaic acid works through several different mechanisms.
Think of it as the multitasker of skincare actives. It's been used in dermatology for decades to treat acne and rosacea, and research also supports its ability to improve certain types of hyperpigmentation. So while the ingredient might be new to your social feed, it's certainly not new to science.
What Does Azelaic Acid Actually Do for Your Skin?
1. Helps Reduce Breakouts
Hormonal acne doesn't always get the memo that you're supposed to be glowing. Azelaic acid helps reduce acne-causing bacteria and normalize the buildup of skin cells inside pores, two factors that contribute to breakouts.
Its anti-inflammatory properties also help calm the redness and swelling associated with inflamed blemishes. The result? A targeted approach to breakouts without relying on retinoids.
2. Helps Fade Dark Spots and Uneven Skin Tone
Here's where azelaic acid gets particularly interesting for maternity skincare.
Pregnancy-related hormonal changes can increase melanin production, contributing to melasma, sometimes called the mask of pregnancy. Azelaic acid inhibits tyrosinase, an enzyme involved in melanin production. By helping regulate excess pigment formation, it can gradually improve the appearance of certain dark spots and uneven tone.
It's also useful for post-inflammatory hyperpigmentation, those lingering marks that sometimes stick around long after a breakout disappears. One ingredient addressing both breakouts and the marks they leave behind? We love a two-for-one.
3. Helps Calm Redness
Azelaic acid has established anti-inflammatory properties and is used in prescription treatments for rosacea, a condition involving inflammatory bumps and persistent facial redness. By helping reduce inflammatory activity in the skin, it can improve redness associated with certain inflammatory skin conditions.
That doesn't mean it treats every cause of facial redness, but it can be particularly useful when inflammation is part of the picture.
4. Supports Smoother-Looking Skin
Azelaic acid helps normalize the way skin cells develop and shed within pores. This can reduce congestion and contribute to smoother-looking skin over time.
It isn't primarily a resurfacing acid, so don't expect the immediate exfoliating sensation associated with stronger AHAs. Its benefits tend to build with consistent use.
Why Is Azelaic Acid Such a Good Fit for Pregnancy?
Pregnancy can introduce a frustrating skincare dilemma. Your hormones are changing, your skin may be behaving differently, and some ingredients you previously relied on are no longer recommended.
Retinoids, for example, are generally avoided during pregnancy. Hydroquinone, another ingredient used to treat hyperpigmentation, is also typically avoided because of safety concerns. That can leave women wondering what they can use to address breakouts and discoloration.
Enter azelaic acid.
The American College of Obstetricians and Gynecologists (ACOG) lists topical azelaic acid among the over-the-counter acne-treatment ingredients that may be used during pregnancy.
The American Academy of Dermatology also considers topical azelaic acid generally safe during pregnancy based on available evidence.
There are three important reasons:
1. Low systemic absorption. Only a limited amount of topically applied azelaic acid is expected to enter the bloodstream when used as directed.
2. Reassuring available safety data. Animal studies have not identified birth defects associated with azelaic acid exposure, although controlled pregnancy studies in humans are limited.
3. Multiple relevant benefits. It can help address acne and hyperpigmentation, two common concerns during pregnancy, without requiring several different targeted actives.
Is Azelaic Acid Good for Melasma?
Melasma is a pigmentary condition often associated with hormonal changes, sun exposure, and genetic susceptibility. It's particularly common during pregnancy. Because azelaic acid helps inhibit excess melanin production, dermatologists may recommend it as part of a melasma treatment plan.
However, results take time, and azelaic acid isn't a guaranteed cure.
Just as important is daily sun protection. UV radiation and visible light can worsen melasma, making broad-spectrum sunscreen an essential part of managing discoloration. For people prone to melasma, a tinted sunscreen containing iron oxides can offer additional protection against visible light.
The takeaway: Azelaic acid can help address existing pigmentation, while sunscreen helps reduce the exposure that can make it worse.
Does Azelaic Acid Have Side Effects?
Even ingredients considered gentle can cause irritation. Azelaic acid may produce temporary tingling, stinging, itching, dryness, or redness, especially when first introduced.
If your skin is already sensitive, start gradually and follow with a moisturizer that supports your skin barrier. Avoid layering several strong actives at once until you know how your skin responds.
How Long Does Azelaic Acid Take to Work?
For acne, some improvement may become noticeable after approximately four weeks, although more substantial results often take longer.
Changes in dark spots and uneven pigmentation may require several months of consistent use.
Azelaic acid isn't an overnight transformation. It's an ingredient that rewards consistency. And when you're dealing with hormonally influenced skin changes, a simple, sustainable routine often makes more sense than constantly switching products.
The Hizo Take
At Hizo, we believe maternity skincare should do more than avoid certain ingredients. It should address the changes women actually experience.
That's why we're interested in clinically studied, multifunctional ingredients like azelaic acid.
When pregnancy can bring breakouts, discoloration, redness, and sensitivity all at once, a targeted ingredient with several complementary benefits can help simplify your routine.
Our approach is rooted in intentional formulations, dermatologist expertise, and barrier-first skincare. Because pregnancy skincare shouldn't mean giving up on results. And it definitely shouldn't require a chemistry degree.
Motherhood changes your skin. We're on it.
