The Ordinary Azelaic Acid Suspension 10% 30 ML

The Ordinary Azelaic Acid Suspension 10% (30 mL)

The Ordinary Azelaic Acid Suspension 10% is a lightweight, cream-gel formula designed to address multiple skin concerns with a high-potency concentration of azelaic acid, a naturally occurring dicarboxylic acid derived from grains like wheat, rye, and barley, and produced by the yeast Malassezia furfur that resides on normal skin. Launched by The Ordinary, a brand under the Deciem umbrella, this product exemplifies their mission to deliver clinically effective ingredients at an accessible price point. Housed in a 30 mL squeeze tube, it offers a fragrance-free, vegan, and cruelty-free formulation suitable for all skin types, particularly those prone to uneven tone, blemishes, redness, or textural irregularities.

Key Ingredient: Azelaic Acid (10%)

Azelaic acid is a multifunctional powerhouse with well-documented dermatological benefits:

• Antioxidant Properties: Neutralizes free radicals, reducing oxidative stress that contributes to inflammation and aging.
• Anti-Inflammatory Effects: Calms redness and irritation, making it a go-to for conditions like rosacea and acne.
• Antibacterial Action: Targets Propionibacterium acnes (now Cutibacterium acnes), a key player in acne development, by inhibiting its growth.
• Tyrosinase Inhibition: Reduces melanin production by inhibiting the enzyme tyrosinase, helping to fade hyperpigmentation and brighten skin tone.
• Keratolytic Activity: Gently exfoliates by normalizing keratinization, unclogging pores, and smoothing skin texture without the harshness of AHAs or BHAs.

At a 10% concentration, this formulation sits in a sweet spot—potent enough to deliver visible results yet gentle enough for daily use, unlike higher prescription strengths (e.g., 15-20%) that may cause more irritation.

Supporting Ingredients

The formula is bolstered by a thoughtfully designed base:

• Dimethicone & Polysilicone-11: Silicones that create a smooth, matte finish, enhance spreadability, and form a breathable barrier to lock in moisture.
• Isodecyl Neopentanoate & Isohexadecane: Lightweight emollients that soften the skin and improve texture without greasiness.
• Dimethyl Isosorbide: A penetration enhancer that ensures deeper delivery of azelaic acid into the skin.
• Tocopherol (Vitamin E): A secondary antioxidant that complements azelaic acid’s protective effects.
• Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer: A thickener that stabilizes the suspension, contributing to its creamy yet non-heavy consistency.

The pH range of 4.0–5.0 aligns with the skin’s natural acidity, minimizing irritation while maintaining efficacy.

Texture and Application Experience

This suspension has a unique cream-gel texture—thicker than a typical serum but lighter than a traditional moisturizer. Some users note a slight “grittiness” upon application due to azelaic acid’s limited solubility in water, though this dissipates as it absorbs. It dries to a matte finish, making it an excellent base for makeup or sunscreen.

Target Concerns

• Uneven Skin Tone: Brightens dull complexions and fades post-inflammatory hyperpigmentation (PIH) from acne or sun exposure.
• Blemishes & Acne: Reduces active breakouts and prevents future ones by tackling bacteria and clogged pores.
• Redness & Rosacea: Soothes inflammation, particularly effective for papulopustular rosacea.
• Textural Irregularities: Smooths rough patches and refines skin surface over time.

Clinical Backing

Research supports azelaic acid’s efficacy:

• Studies in The Journal of Clinical and Aesthetic Dermatology highlight its role in reducing rosacea-related inflammation via antioxidant mechanisms.
• Its ability to inhibit tyrosinase and treat hyperpigmentation is well-documented in dermatological literature, with 10% concentrations showing measurable results after consistent use (typically 8–12 weeks).
• Its antibacterial and comedolytic properties make it a staple in acne management, often compared to benzoyl peroxide but with less irritation.

Pros

• Affordable (~$10 USD for 30 mL) compared to prescription alternatives.
• Multi-benefit ingredient tackles multiple concerns simultaneously.
• Gentle enough for sensitive skin with a low irritation profile.
• Fragrance-free and non-comedogenic.

Cons

• Gritty texture may feel odd initially or pill if layered improperly with other products.
• Not inherently hydrating—dry skin types may need a separate moisturizer.
• Results require patience (visible improvements often take 4–12 weeks).

How to Incorporate The Ordinary Azelaic Acid Suspension 10% (30 mL)

Step 1: Preparation

• Cleanse: Start with a gentle cleanser (e.g., The Ordinary Squalane Cleanser) to remove dirt, oil, and impurities. Pat skin dry with a clean towel.
• Tone (Optional): Apply a hydrating toner if desired, such as one with hyaluronic acid, to prep skin and boost moisture.

Step 2: Patch Test (First-Time Users)

• Before full application, test the product on a small area (e.g., inner forearm or behind the ear) to check for sensitivity. Wait 24 hours. If no irritation occurs, proceed.

Step 3: Application

• Amount: Dispense a pea-sized amount (about 0.5–1 mL) from the tube.
• Technique: Apply evenly across the face using clean fingertips, avoiding the eye area, lips, and mucous membranes. Gently massage until absorbed.
• Frequency: Use once daily—either morning (AM) or evening (PM)—depending on your routine. For sensitive skin, start with 2–3 times per week and gradually increase to daily use as tolerated.

Step 4: Layering

• Order: Apply after water-based serums (e.g., The Ordinary Niacinamide 10% + Zinc 1%) but before heavier creams or oils. Its silicone content makes it a mid-step product.
• Compatibility: Avoid using in the same routine as direct acids (e.g., glycolic acid), retinoids, pure vitamin C, or peptides to prevent irritation or pilling. Pair with hydrating products like The Ordinary Natural Moisturizing Factors + HA for balance.
• Morning Use: Follow with a broad-spectrum sunscreen (SPF 30+) to protect skin, as azelaic acid doesn’t increase sun sensitivity but UV exposure can worsen pigmentation.

Step 5: Moisturize (If Needed)

• If skin feels dry post-application, layer a lightweight moisturizer over the suspension once it’s fully absorbed (about 1–2 minutes).

Step 6: Monitor & Adjust

• Timeline: Expect subtle improvements in texture and brightness within 2–4 weeks, with significant results (e.g., reduced pigmentation or acne) after 8–12 weeks of consistent use.
• Sensitivity: If stinging or redness occurs, reduce frequency or buffer by mixing with a moisturizer. Discontinue if irritation persists.

Tips for Best Results

• Store in a cool, dry place away from direct sunlight to maintain stability.
• Use consistently—azelaic acid’s benefits compound over time.
• Pair with complementary actives like niacinamide (for oil control) or hyaluronic acid (for hydration) in separate routines.

Final Notes

The Ordinary Azelaic Acid Suspension 10% (30 mL) is a versatile, budget-friendly option for those seeking a gentle yet effective solution for acne, redness, hyperpigmentation, and uneven texture. Its research-backed formulation and straightforward application process make it a staple for beginners and seasoned skincare enthusiasts alike. Patience and proper integration into a routine are key to unlocking its full potential.
