Azelan Gel
Product Description
Product overview
Bayer Azelan Gel is a dermatologist-trusted, prescription-strength topical gel formulated with 15% Azelaic Acid — a naturally occurring dicarboxylic acid clinically proven to reduce acne-causing bacteria, fight inflammatory papules and pustules, fade post-inflammatory hyperpigmentation, and calm rosacea-related redness. Its lightweight, fast-absorbing gel base is fragrance-free, paraben-free, and developed by Bayer, one of the world's leading pharmaceutical companies.
Clinically Proven Acne Fighter
15% Azelaic Acid inhibits Cutibacterium acnes and Staphylococcus epidermidis protein synthesis, clearing inflammatory papules and pustules backed by multiple RCTs.
Texture & feel
SENSORYClinically Proven Acne Fighter
15% Azelaic Acid inhibits Cutibacterium acnes and Staphylococcus epidermidis protein synthesis, clearing inflammatory papules and pustules backed by multiple RCTs.
Rosacea Calming
FDA-recognized for mild-to-moderate papulopustular rosacea. Reduces reactive oxygen species responsible for erythema and inflammatory flushing.
Hyperpigmentation Correction
Acts as a tyrosinase inhibitor to reduce melanin overproduction, visibly fading post-acne dark spots, melasma, and post-inflammatory hyperpigmentation.
Pregnancy & Breastfeeding Safe
Classified as FDA Pregnancy Category B. Less than 4% of the applied dose is systemically absorbed, making it one of the safest prescription actives for expectant mothers.
Comedolytic & Keratolytic
Normalises abnormal keratinisation inside the hair follicle, preventing comedone formation and refining skin texture without harsh exfoliants.
Non-Photosensitising
Unlike AHAs and retinoids, Azelaic Acid does not increase UV sensitivity, making it safe for year-round morning or evening use without mandatory SPF escalation.
Safety & compatibility
SAFEAzelaic Acid is classified as Pregnancy Category B. Systemic absorption is less than 4% of the topical dose. Recommended by the AAD and NIH as safe during pregnancy and lactation. Do not apply to nipple or breast area while breastfeeding.
Polysorbate 80 and Lecithin (potentially soy-derived) are present in this formula and may feed Malassezia yeast. If you are managing fungal acne, consult a dermatologist before use. The Azelaic Acid itself is antifungal and may offset this risk.
The gel base is water-dominant and non-occlusive. Caprylic/Capric Triglycerides rate 1/5 on the comedogenic scale. No heavy oils or butters. Suitable for acne-prone skin.
Free from fragrances, parabens, sulfates, common allergens, and harsh alcohols. Clinically shown to produce only mild, transient irritation in most users. Patch test recommended for reactive skin.
Azelaic Acid is generally well-tolerated alongside most actives. It can be layered with niacinamide, vitamin C, and low-strength AHA/BHA. Use caution with high-strength retinoids — alternate evenings if irritation occurs.
Azelaic Acid inhibits tyrosinase and may cause temporary skin lightening (hypopigmentation) at the application site in darker skin tones. Monitor treated areas and consult a dermatologist if lightening is observed beyond the intended dark spots.
Unlike AHAs, BHAs, and retinoids, Azelaic Acid does not increase UV sensitivity. SPF is still recommended as a general skincare best practice, but there is no mandatory sun avoidance requirement with this gel.
Up to 5–10% of users report a mild burning or stinging sensation in the first 2–4 weeks of use. This is typically transient and resolves as skin adjusts. Start with once-daily application and build up to twice-daily as tolerated.
Ingredient breakdown
INGREDIENTSAzelaic Acid 15% (150mg/g)Proven
The star active ingredient. A naturally occurring saturated dicarboxylic acid found in grains like wheat, rye, and barley — and also produced by Malassezia yeast on human skin. At 15%, it meets prescription strength for treating acne vulgaris and papulopustular rosacea.
- Mechanism: Inhibits bacterial protein synthesis in Cutibacterium acnes and Staphylococcus epidermidis
- Anti-inflammatory: Scavenges reactive oxygen species (ROS) produced by neutrophils, reducing redness and swelling
- Keratolytic: Normalises abnormal keratinisation of follicular epithelium, preventing comedone formation
- Anti-melanogenic: Inhibits tyrosinase enzyme, reducing melanin synthesis and fading PIH, melasma
- Clinical efficacy (RCTs): 51% mean improvement in erythema at 12 weeks vs. 36% with vehicle (meta-analysis of 3 RCTs, n=1,624); 20% reduction in acne comedones at 3 months in 70% of patients vs. 14% with vehicle
- Systemic absorption: <4% of topical dose absorbed; plasma levels remain within normal endogenous range
Propylene Glycol ~12%Proven
A multifunctional humectant that draws moisture into the skin and improves the spreading and penetration of Azelaic Acid. Also functions as an antimicrobial co-preservative and prevents the gel from freezing or separating.
- Role: Humectant, solvent, penetration enhancer, antimicrobial stabiliser
- Benefit: Helps Azelaic Acid reach the target follicular environment more efficiently
- Safety: Well-established safety profile at cosmetic concentrations; generally non-irritating
Polysorbate 80 Low conc.Proven
A water-soluble emulsifier derived from polyethoxylated sorbitan and oleic acid. Keeps the oil-phase ingredients (lecithin, triglycerides) uniformly dispersed in the water-based gel, ensuring consistent product texture and ingredient delivery.
- Role: Surfactant, emulsifier, solubiliser
- Benefit: Ensures gel stability and even distribution of all actives
Lecithin Low conc.Promising
A phospholipid complex from plant (typically soy) sources. Functions as an emollient and emulsifier, softening the skin and helping form liposomes that can carry Azelaic Acid deeper into the follicular layer for improved bioavailability.
- Role: Emollient, emulsifier, penetration facilitator via liposome formation
- Benefit: Enhances Azelaic Acid delivery; softens and moisturises skin barrier
Carbomer ~0.5–1%Proven
A high-molecular-weight polyacrylic acid polymer that gives the gel its characteristic smooth, spreadable consistency. Carbomer's large molecular size means it stays on the skin surface and does not penetrate, classifying it as an inert, well-tolerated gelling agent.
- Role: Gelling agent, rheology modifier, viscosity stabiliser
- Penetration: Minimal — large molecule size prevents skin penetration
- Safety: Considered inert; very low irritation potential at standard concentrations (<1%)
Caprylic/Capric Triglycerides (C10-18 Triglycerides) Low conc.Proven
A lightweight emollient derived from glycerin and coconut oil. Behaves like an oil in texture but is chemically distinct — acting as a skin-softener and solvent that helps dissolve and deliver other ingredients while preventing transepidermal water loss.
- Role: Emollient, solvent, texture enhancer
- Comedogenic rating: 1/5 — very low risk of pore-clogging despite coconut origin
- Benefit: Improves spreadability; counteracts the potential drying effect of Azelaic Acid
Sodium Hydroxide Trace / pH adj.Proven
Also known as lye, used in minute quantities to adjust the gel's pH to the optimal range (around 3.5–4.5) where Azelaic Acid is most effective. The finished product is neutralised and safe — sodium hydroxide is not present as a caustic compound in the final formula.
- Role: pH adjuster, buffer
- Purpose: Ensures Azelaic Acid remains stable and bioavailable at the correct acidic pH
Disodium EDTA TraceProven
A chelating agent that binds and deactivates trace metal ions that can enter a product from water, packaging, or air. By neutralising these ions, Disodium EDTA enhances the effectiveness of other preservatives and extends overall product stability.
- Role: Chelating agent, preservative booster, formula stabiliser
- Mild penetration enhancement: Can marginally increase the absorption of co-formulated actives
- Safety: Considered safe in cosmetic products by the CIR Expert Panel
Benzoic Acid ~0.1%Proven
A naturally occurring preservative found in strawberries, cinnamon, and cloves. Added primarily to inhibit fungal and yeast growth, extending the product's shelf life. Works synergistically with Disodium EDTA for broad-spectrum preservation.
- Role: Preservative (antifungal focus), pH buffer
- Antimicrobial spectrum: Primarily antifungal; less effective against bacteria alone — hence paired with other preservatives
- Safety: Approved EU/FDA preservative at concentrations up to 2.5% in leave-on products
Water (Aqua) Base / MajorProven
The primary solvent and carrier in this formula. Water-dominant base makes the gel lightweight, non-greasy, and fast-absorbing — ideal for oily, acne-prone, and combination skin types. Also helps maintain hydration at the skin surface during treatment.
- Role: Solvent, vehicle, hydration base
- Benefit: Enables water-soluble ingredients to dissolve and absorb effectively

Where it fits in your routine
ROUTINEApply to clean, dry skin before heavier serums and moisturisers. Can be used AM and/or PM. Not photosensitising — sunscreen is still recommended as a general skin protection practice.
How to use
HOW TO USECleanse Thoroughly
Wash the affected area with a gentle, non-stripping cleanser and lukewarm water. Pat dry gently with a clean towel — do not rub. Avoid harsh exfoliating cleansers before application.
Apply a Thin Layer
Dispense a small, pea-sized amount of Azelan Gel onto your fingertips. Gently massage into the affected areas using upward circular motions. A thin, even layer is sufficient — more product does not increase efficacy and may increase irritation.
Allow to Absorb (30–60 seconds)
Let the gel absorb fully before applying the next skincare step. The lightweight, water-based formula absorbs rapidly without leaving residue. Avoid touching the treated area before it has dried.
Follow With Moisturiser
Apply a lightweight, non-comedogenic moisturiser to counteract any initial dryness. This is especially important in the first 2–4 weeks while skin adjusts to the active ingredient. For oily skin, a gel-moisturiser works best.
Use Twice Daily (AM & PM)
For best results, apply morning and evening. If stinging or irritation occurs, begin with once-daily (PM) application and increase to twice-daily as skin acclimatises, typically within 2–4 weeks. Continue for at least 4 weeks for acne and up to 12 weeks for rosacea improvement.
Wash Hands After Application
Wash hands with soap and water after applying the gel. Avoid contact with eyes, mouth, and mucous membranes. If accidental eye contact occurs, rinse thoroughly with water immediately.
Who is it for?
WHOPerfect for you if:
- You have mild-to-moderate acne vulgaris (comedonal or inflammatory)
- You experience papulopustular rosacea with redness and bumps
- You have post-inflammatory hyperpigmentation (PIH) or acne scars
- You are pregnant or breastfeeding and need a prescription-strength acne treatment
- You have oily, combination, or sensitive-acne-prone skin
- You want a non-photosensitising active for year-round AM/PM use
- You are seeking an alternative to retinoids with fewer side effects
- You have darker skin tones with post-acne discolouration needing gentle brightening
Consider alternatives if:
- You have confirmed, active fungal acne (Malassezia folliculitis) — some ingredients may trigger it
- You have known hypersensitivity to Azelaic Acid or Propylene Glycol
- You have severe nodulocystic acne — oral treatments may be required alongside topical therapy
- You need rapid, within-days results — Azelaic Acid requires 4–12 weeks for visible improvement
- You prefer minimal-ingredient formulas (10 ingredients, but includes emulsifiers)
- You have very dry or eczema-prone skin without access to a rich moisturiser to layer on top
Skin type compatibility
SKIN TYPESThe ideal candidate. Lightweight gel absorbs instantly without adding grease. Targets bacteria, unclogs pores, and reduces sebum-driven inflammation. Non-comedogenic rating of 1/5.
Performs equally well across oily T-zone and drier cheek zones. Gel texture balances without over-drying, making it one of the most versatile actives for combination skin.
Fragrance-free and paraben-free. Clinically validated for rosacea. Initial stinging (5–10% of users) is usually transient. Start with once-daily application and build tolerance gradually.
The gel formula may exacerbate dryness initially. Must be paired with a rich, non-comedogenic moisturiser. Azelaic Acid itself does not cause dryness, but the thin gel base provides minimal moisturisation.
Excellent for fading PIH and melasma common in deeper skin tones. Monitor for hypopigmentation at treated sites — a known but uncommon side effect. Consult a dermatologist for personalised use.
Results timeline
WEEK 10–12Initial Adjustment & Gentle Exfoliation
Mild tingling or stinging may occur — this is normal and usually subsides. Some users notice initial skin purging as Azelaic Acid begins accelerating cellular turnover and bringing underlying congestion to the surface. Keep moisturiser close.
~10–15% see early improvement in rednessVisible Reduction in Active Breakouts
Most users report a measurable decrease in inflamed papules and pustules. Skin texture begins to refine. Stinging sensations diminish as the skin adapts. Redness from existing spots starts to fade.
~42% report good-to-excellent improvement by week 4Significant Acne Clearance & Tone Evening
Consistent twice-daily users see substantial reductions in lesion count. Post-inflammatory hyperpigmentation (PIH) begins to fade noticeably. Rosacea patients observe improved erythema and fewer papulopustular flares.
~64% achieve good-to-excellent acne improvement at 3 monthsSustained Clearance & Rosacea Control
Rosacea patients typically reach peak therapeutic benefit at 12 weeks. Acne patients experience a significant reduction in total lesion count with improved skin texture. PIH markedly reduced. Maintenance use sustains results.

Frequently asked questions
FAQYes — Azelaic Acid is classified as FDA Pregnancy Category B, meaning animal studies show no fetal risk at standard doses and it is widely recommended by dermatologists for pregnant patients. Less than 4% of the topical dose is systemically absorbed, keeping blood levels within normal endogenous ranges. The AAD, NIH, and multiple dermatology authorities confirm it is safe to use during both pregnancy and breastfeeding. During breastfeeding, avoid applying to the breast or nipple area and ensure the infant's skin does not contact treated areas. Always consult your healthcare provider before beginning any new medication during pregnancy.
Use with caution. Azelan Gel contains two ingredients that are flagged as potentially problematic for fungal acne (Malassezia folliculitis): Polysorbate 80 (an emulsifier) and Lecithin (likely soy-derived). Both can theoretically feed Malassezia yeast. That said, Azelaic Acid itself has demonstrated antifungal properties — Malassezia is actually the natural source of Azelaic Acid in the body — so the active ingredient may partially offset this risk. If you have confirmed fungal acne, consult a dermatologist before use. For straightforward bacterial acne, the formula is appropriate.
Generally yes — Azelaic Acid is one of the most compatible prescription actives. It works well layered with niacinamide (for enhanced brightening), vitamin C (for antioxidant support), and low-strength AHA/BHA exfoliants. With retinoids: Azelaic Acid is often used as a gentler alternative to retinoids and can technically be combined, but using both simultaneously may increase irritation risk — especially for beginners. Consider alternating evenings (retinoid one night, Azelan Gel the next) until your skin builds tolerance. Avoid mixing with very strong acids (high-% glycolic acid, high-% salicylic acid) in the same application to minimise irritation. As always, introduce one active at a time and patch test.
Azelan Gel is most suited to oily, combination, and acne-prone skin types thanks to its lightweight, water-based gel formula that absorbs without greasiness. It is also excellent for sensitive and rosacea-prone skin — being fragrance-free and paraben-free, it is one of the few prescription-strength actives gentle enough for reactive complexions. Darker skin tones benefit significantly from its ability to fade post-inflammatory hyperpigmentation. Dry skin types can use it, but must pair it with a rich, non-comedogenic moisturiser to counteract any initial tightness. Not recommended as a standalone treatment for very dry or eczema-prone skin without professional guidance.
Results timeline varies by condition. For acne: most users notice a measurable reduction in active papules and pustules within 4 weeks of twice-daily use. Good-to-excellent acne improvement is achieved in approximately 64% of patients by 3 months. For rosacea: clinical studies show significant improvement at 12–15 weeks of consistent use, with peak erythema reduction (~51% mean improvement) at 12 weeks. For post-inflammatory hyperpigmentation (PIH): fading of dark spots typically becomes visible at 6–8 weeks, with more pronounced brightening at 12 weeks. Consistency is key — do not discontinue treatment during the initial adjustment phase (weeks 1–4).
Apply Azelan Gel as your treatment step — after cleansing and toning, but before heavier serums and moisturisers. The general order is: Cleanser → Toner (optional) → Azelan Gel → Lightweight Serum (optional) → Moisturiser → Sunscreen (AM only). Allow the gel to absorb fully (30–60 seconds) before layering the next product. It can be used in both AM and PM routines since Azelaic Acid is not photosensitising. If combining with a strong active (retinoid, high-% vitamin C), apply the active with the lower pH first and allow absorption before applying Azelan Gel.
No — Azelan Gel has a low comedogenic rating of 1/5. The formula is water-dominant with a lightweight gel base. The Caprylic/Capric Triglycerides, while derived from coconut oil, rate 1/5 on the comedogenic scale and do not clog pores in gel concentrations. Azelaic Acid itself is comedolytic, meaning it actively works to clear clogged follicles and prevent new comedone formation. The formula contains no heavy oils, waxes, or silicones. Suitable for pore-conscious, acne-prone, and oily skin types without concern of pore congestion.
Azelan Gel has a Period After Opening (PAO) of 12 months. Once the tube is opened, use within one year for guaranteed stability and potency. Store at room temperature below 25°C, away from direct sunlight and extreme temperatures. Do not freeze. Check the physical appearance of the gel before each use — discard if it changes colour (yellowing), texture (separation), or develops an unusual odour before the 12-month window. A standard 30g tube, used twice daily on the affected area, will typically last 2–3 months with normal use.
Verdict: Bayer Azelan Gel is a gold-standard, pharmaceutical-grade treatment for acne, rosacea, and post-inflammatory hyperpigmentation. Its 15% Azelaic Acid concentration — backed by decades of RCT evidence and FDA recognition — delivers clinically meaningful results for a wide range of skin concerns, with an exemplary safety profile that extends to pregnancy and breastfeeding. The minimal 10-ingredient formula is fragrance-free, paraben-free, non-comedogenic, and non-photosensitising, making it one of the most versatile prescription-strength actives available. The key caveats: patience is required (4–12 weeks for full results), the gel base needs moisturiser support, and those with fungal acne should proceed with caution due to Polysorbate 80 and Lecithin in the formula. For those seeking a clinically proven, pregnancy-safe, dermatologist-trusted active treatment, Bayer Azelan Gel is an outstanding choice backed by Bayer AG's pharmaceutical expertise.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
