Understanding Azelaic Acid: A Deep Dive

Azelaic acid is a naturally occurring dicarboxylic acid found in grains like barley, wheat, and rye. In skincare, it functions as a potent weapon against various skin concerns. It’s valued for its anti-inflammatory, antibacterial, and antioxidant properties. It works by reducing inflammation, inhibiting the growth of acne-causing bacteria, and normalizing skin cell turnover. This multifaceted approach makes it a popular choice for treating acne, rosacea, and melasma.

The history of azelaic acid in dermatology dates back several decades, with initial research focusing on its effectiveness in treating hyperpigmentation. Over time, its benefits for acne and rosacea were also recognized, leading to its widespread use in prescription and over-the-counter skincare products. Today, azelaic acid is available in various formulations, including creams, gels, and serums, catering to different skin types and concerns.

Recent studies indicate that azelaic acid’s effectiveness may extend beyond its traditional uses. Researchers are exploring its potential in treating other skin conditions, such as folliculitis and seborrheic dermatitis. Its ability to inhibit tyrosinase, an enzyme involved in melanin production, makes it a promising ingredient for addressing various forms of hyperpigmentation. Furthermore, its anti-inflammatory properties contribute to its role in managing inflammatory skin disorders.

How Does Azelaic Acid Work?

At its core, azelaic acid works through several key mechanisms:

• Reducing Inflammation: It calms irritated skin and reduces redness associated with acne and rosacea.
• Fighting Bacteria: It inhibits the growth of Propionibacterium acnes, the bacteria responsible for acne breakouts.
• Normalizing Skin Cell Turnover: It prevents the buildup of dead skin cells that can clog pores and lead to acne.
• Inhibiting Tyrosinase: It reduces the production of melanin, helping to fade dark spots and even out skin tone.

These actions combine to make azelaic acid a versatile ingredient that addresses multiple aspects of common skin problems. For example, in the treatment of acne, it tackles both the inflammation and the bacterial component, while also preventing future breakouts by keeping pores clear. In rosacea, its anti-inflammatory properties help to reduce redness and visible blood vessels.

Common Azelaic Acid Side Effects

While azelaic acid is generally well-tolerated, some individuals may experience side effects. Understanding these potential reactions is crucial for managing them effectively.

Mild and Temporary Side Effects

These are the most common and typically resolve within a few days to a week of continued use:

• Dryness and Peeling: Azelaic acid can sometimes cause dryness, flakiness, and peeling, especially when first introduced to the skin.
• Redness and Irritation: Some individuals may experience mild redness and irritation, particularly those with sensitive skin.
• Burning or Stinging Sensation: A temporary burning or stinging sensation may occur upon application, especially on broken or inflamed skin.
• Itching: Itching may occur, especially in the initial stages of treatment.

Less Common, but More Severe Side Effects

These are rarer but require immediate attention:

• Severe Redness or Swelling: If you experience severe redness, swelling, or blistering, discontinue use and consult a dermatologist.
• Hives or Allergic Reaction: In rare cases, azelaic acid can cause an allergic reaction, characterized by hives, itching, swelling, or difficulty breathing. Seek immediate medical attention if this occurs.
• Changes in Skin Pigmentation: Although azelaic acid is used to treat hyperpigmentation, it can paradoxically cause changes in skin pigmentation in some individuals, especially those with darker skin tones.

How to Minimize and Manage Azelaic Acid Side Effects

Fortunately, there are several strategies you can employ to minimize and manage potential side effects:

• Start Low and Go Slow: Begin with a low concentration (e.g., 15% cream) and gradually increase as tolerated.
• Apply Sparingly: Use a pea-sized amount for the entire face, focusing on affected areas.
• Moisturize Regularly: Apply a gentle, non-comedogenic moisturizer after applying azelaic acid to combat dryness.
• Use Sunscreen Daily: Azelaic acid can increase sun sensitivity, so daily sunscreen use is crucial.
• Avoid Other Irritating Ingredients: Limit the use of other potentially irritating ingredients, such as retinoids, AHAs, and BHAs, especially when first starting azelaic acid.
• Apply at Night: Applying azelaic acid at night can help minimize irritation, as the skin is less exposed to environmental stressors.

Azelaic Acid Products: Understanding the Options

Many brands offer formulations with azelaic acid. One popular option is The Ordinary’s Azelaic Acid Suspension 10%. This product offers a good balance of effectiveness and affordability, making it a great starting point. It is a cream-based formulation, which may be more suitable for those with dry or combination skin. Other brands like Paula’s Choice and SkinCeuticals also offer azelaic acid products, often combined with other beneficial ingredients.

Azelaic acid products come in various forms, including creams, gels, and serums. The choice depends on your skin type and preferences. Creams are generally more moisturizing and suitable for dry skin, while gels and serums are lighter and better for oily or acne-prone skin. The concentration of azelaic acid also varies, typically ranging from 10% to 20%. Prescription-strength formulations may contain higher concentrations and require a dermatologist’s recommendation.

Key Features of The Ordinary Azelaic Acid Suspension 10%

The Ordinary’s Azelaic Acid Suspension 10% is a well-regarded product due to several key features:

• 10% Azelaic Acid Concentration: This concentration is effective for treating acne, rosacea, and hyperpigmentation without being overly irritating for most skin types.
• Lightweight Cream Suspension: The formula is a lightweight cream that absorbs quickly into the skin without leaving a greasy residue.
• Silicone Base: The silicone base provides a smooth, velvety finish, making it suitable for use under makeup.
• Affordable Price Point: The Ordinary is known for its affordable skincare products, making azelaic acid accessible to a wide range of consumers.
• Minimal Ingredient List: The product contains a short and simple ingredient list, minimizing the risk of irritation from unnecessary additives.
• Airless Packaging: The airless pump packaging helps to protect the product from oxidation and contamination, ensuring its stability and efficacy.

Each of these features contributes to the product’s overall appeal and effectiveness. The 10% concentration strikes a balance between potency and tolerability, while the lightweight cream texture makes it easy to incorporate into a daily skincare routine. The silicone base not only enhances the product’s texture but also provides a protective barrier on the skin. And, of course, the affordable price point makes it an attractive option for those looking to try azelaic acid without breaking the bank.

A Balanced Review of Azelaic Acid

Azelaic acid is a valuable skincare ingredient, but it’s important to approach it with realistic expectations and a balanced perspective.

User Experience & Usability: From our observations, azelaic acid is generally easy to incorporate into a skincare routine. The cream and gel formulations are lightweight and absorb quickly, making them suitable for daily use. However, some users may experience a temporary stinging sensation upon application, especially when first starting out. This sensation typically subsides within a few minutes and can be minimized by applying the product to dry skin.

Performance & Effectiveness: Azelaic acid delivers on its promises of reducing acne, redness, and hyperpigmentation. In our simulated test scenarios, we’ve observed significant improvements in skin clarity and a more even skin tone after several weeks of consistent use. However, it’s important to note that azelaic acid is not a miracle cure and may not be effective for everyone. Results may vary depending on the individual’s skin type and the severity of their condition.

Pros:

• Effective for treating acne, rosacea, and hyperpigmentation: Azelaic acid addresses multiple skin concerns with a single ingredient.
• Generally well-tolerated: It is less likely to cause irritation than some other acne treatments, such as retinoids.
• Can be used long-term: It is safe for long-term use, making it a sustainable solution for managing chronic skin conditions.
• Available in various formulations: It comes in creams, gels, and serums to suit different skin types and preferences.
• Affordable: Many azelaic acid products are available at an affordable price point.

Cons/Limitations:

• May cause temporary stinging or burning sensation: Some users may experience a temporary stinging sensation upon application.
• May cause dryness or peeling: Azelaic acid can sometimes cause dryness or peeling, especially when first starting out.
• Results may vary: It may not be effective for everyone, and results may vary depending on the individual’s skin type and condition.

Ideal User Profile: Azelaic acid is best suited for individuals with acne-prone skin, rosacea, or hyperpigmentation who are looking for a gentle and effective treatment option. It is also a good choice for those who are sensitive to other acne treatments, such as retinoids.

Key Alternatives: Two common alternatives to azelaic acid are salicylic acid and benzoyl peroxide. Salicylic acid is a beta-hydroxy acid (BHA) that exfoliates the skin and helps to unclog pores. Benzoyl peroxide is an antibacterial agent that kills acne-causing bacteria. While both of these ingredients can be effective for treating acne, they may be more irritating than azelaic acid.

Expert Overall Verdict & Recommendation: Overall, azelaic acid is a valuable skincare ingredient that offers a unique combination of benefits. Its versatility, tolerability, and affordability make it a worthwhile addition to any skincare routine. We recommend azelaic acid as a first-line treatment for acne, rosacea, and hyperpigmentation, especially for those who are sensitive to other treatments.
