Part of our complete guide to acne in the UK. [Link to be activated on publication of conditions page]
Skinoren is one of the most versatile prescription treatments available for acne and skin discolouration in the UK — licensed for both acne vulgaris and rosacea, and widely used for post-inflammatory hyperpigmentation and melasma. It is the only topical acne treatment that does not contribute to antibiotic resistance.
Whether you are looking for Skinoren cream for acne, Skinoren gel for oily or combination skin, or simply trying to understand what makes this treatment different from the alternatives, this guide covers everything you need to know. We explain how Skinoren works, who it is suitable for, how to use it correctly, and how to buy Skinoren safely through a GPhC-regulated online pharmacy.

View Skinoren Cream →What Is Skinoren?
Skinoren is a branded topical treatment containing azelaic acid as its active ingredient. It is manufactured by Bayer and is widely prescribed across the UK and Europe for acne vulgaris and rosacea. Skinoren is available in two formulations:
- Skinoren Cream 20% — a white, water-based cream suitable for sensitive or dry skin
- Skinoren Gel 15% — a lighter, alcohol-free gel better suited to oily or combination skin
The difference between Skinoren cream and Skinoren gel is primarily one of texture and skin type compatibility rather than mechanism. Both formulations deliver azelaic acid to the skin, where it works across several pathways to clear breakouts and even skin tone.
How Does Skinoren Work? The Science of Azelaic Acid
Azelaic acid is a naturally occurring dicarboxylic acid found in grains such as wheat, rye, and barley. When applied topically, it acts through several complementary mechanisms that make it particularly effective for inflammatory acne and post-inflammatory hyperpigmentation.
Antibacterial Action
Inhibits the growth of Cutibacterium acnes, the bacterium most closely associated with inflammatory acne. Unlike topical antibiotics, azelaic acid does not contribute to antibiotic resistance — a significant clinical advantage given growing concerns about antibiotic stewardship in dermatology.
Keratolytic & Comedolytic Effects
Normalises the keratinisation process inside the pilosebaceous unit. By reducing abnormal shedding of skin cells inside the follicle, it prevents the formation of comedones (blackheads and whiteheads) that underlie acne lesions.
Anti-inflammatory Properties
Reduces the inflammatory response associated with active acne lesions. Particularly relevant for patients who experience red, tender papules and pustules, and for rosacea where chronic low-grade inflammation drives flushing and skin sensitivity.
Tyrosinase Inhibition
Inhibits tyrosinase — the enzyme responsible for melanin production. This makes Skinoren effective for post-inflammatory hyperpigmentation (PIH) and melasma. It selectively targets hyperactive melanocytes without bleaching normal surrounding skin.
Safe for darker skin tones: Unlike hydroquinone, azelaic acid selectively targets overactive melanocytes and does not depigment normal skin. This makes it particularly well-suited to Fitzpatrick skin types IV–VI, where PIH is a common and often distressing complication of acne.
Skinoren Cream vs Skinoren Gel: Which Should You Use?
Both formulations deliver azelaic acid effectively. The right choice depends on your skin type, primary concern, and how your skin responds to different textures.
| Feature | Skinoren Cream 20% | Skinoren Gel 15% |
|---|---|---|
| Active ingredient | Azelaic acid 20% | Azelaic acid 15% |
| Texture | Thick, water-based cream | Lightweight, clear gel |
| Best skin type | Dry or sensitive skin | Oily or combination skin |
| Feel on skin | Moisturising and soothing | Fast-absorbing, matte finish |
| Alcohol content | None | None |
| Suitable for rosacea | ✓ Yes | ✓ Yes |
| Suitable for PIH | ✓ Yes | ✓ Yes |
| Comedogenicity | Low | Non-comedogenic |

Acne Vulgaris
Skinoren is licensed for mild-to-moderate acne vulgaris. It is effective against both non-inflammatory acne (comedones) and inflammatory acne (papules and pustules). Clinical studies referenced in NICE guidelines support its use as a first-line or adjunct treatment, particularly for patients who cannot tolerate — or do not wish to use — topical antibiotics. Unlike benzoyl peroxide, azelaic acid does not bleach fabrics or hair. Unlike topical retinoids, it does not typically cause a pronounced purging phase and is considered safe in pregnancy under clinical guidance. For a broader overview: All You Need to Know About Acne.
Post-Inflammatory Hyperpigmentation (PIH)
PIH is one of the most common and distressing consequences of acne, particularly in patients with Fitzpatrick skin types III–VI. After inflammatory lesions resolve, excess melanin deposition can leave marks that persist for months or years. Skinoren’s tyrosinase inhibition makes it one of the most evidence-based topical treatments for PIH, often used alongside broad-spectrum SPF to prevent further pigment stimulation.
Rosacea
Azelaic acid is one of the few topical treatments with a licensed indication for both acne and rosacea. Skinoren 15% gel and 20% cream can reduce rosacea-associated papules, pustules, and erythema. Patients with rosacea should avoid known triggers such as UV exposure, alcohol, and spicy food alongside topical treatment.
Melasma and Hormonal Pigmentation
Melasma — patchy hyperpigmentation often triggered by pregnancy, hormonal contraception, or PCOS — is commonly managed with azelaic acid. Skinoren is considered a safer option than hydroquinone (no longer widely prescribed in the UK) and can be used as part of a broader melasma management plan including photoprotection and, where indicated, hormonal review.
How to Use Skinoren Correctly
Correct application maximises results and reduces the risk of irritation. Apply twice daily to clean, dry skin across the entire affected area — not only to individual spots. Use a pea-sized amount, spread thinly with gentle circular motions, and allow to absorb fully before applying other products.
1
Cleanse
Wash the affected area with a gentle, non-comedogenic cleanser. Pat dry — do not scrub.
2
Apply Skinoren
Apply a pea-sized amount thinly across all affected areas twice daily (morning and evening). Apply to the whole affected area, not just active spots. Avoid the eye and mouth area.
3
Moisturise
Apply a fragrance-free, non-comedogenic moisturiser over the top if needed — especially if you experience dryness or tingling. Allow Skinoren to absorb for a few minutes first.
4
SPF (morning only)
Apply a broad-spectrum SPF 30 or higher every morning. Essential when treating PIH or melasma, as UV exposure will counteract treatment progress.
Tip — if you experience irritation: If stinging or dryness is significant in the first two weeks, reduce to once-daily application in the evening until your skin adjusts, then build back to twice daily. Alternatively, apply a thin layer of unfragranced moisturiser first, wait two minutes, then apply Skinoren on top.
The Purging Phase
Some patients notice a temporary worsening of acne in the first two to four weeks of treatment as the treatment accelerates cell turnover and brings existing microcomedones to the surface. Purging with azelaic acid is generally milder than with retinoids. A significant increase in breakouts that persists beyond four weeks should be assessed by your prescriber.

Find my Skinoren →Side Effects: What to Expect
Skinoren is well tolerated by the majority of patients, but some side effects can occur — particularly in the first few weeks of use.
| Side effect | How common | Management |
|---|---|---|
| Tingling or stinging on application | Very common (first 2–3 weeks) | Buffering technique; start once daily |
| Dryness or flaking | Common | Add unfragranced moisturiser; reduce frequency temporarily |
| Mild redness or itching | Common (settles over weeks) | Reduce frequency; review with prescriber if persistent |
| Temporary skin lightening at application site | Uncommon | Apply only to affected area; not a sign of permanent change |
| Allergic contact dermatitis | Less common | Discontinue; contact your prescriber |
| Severe burning, widespread rash or facial swelling | Rare | Discontinue immediately; seek urgent medical advice |
Seek urgent care if: You experience severe burning, widespread hives or rash across the body, facial swelling, or difficulty breathing after applying Skinoren. These may indicate a hypersensitivity reaction. Call 111 or attend your nearest urgent treatment centre.
Safe in pregnancy: Azelaic acid is generally considered one of the safer topical acne options during pregnancy, particularly in comparison to retinoids. Always discuss any treatment with your prescriber or midwife before use.
Skinoren vs Other Acne Treatments

Read the guide →Skinoren as Part of a Wider Skincare Routine
Skinoren works best as part of a consistent, simplified skincare routine. Using the right supporting products improves tolerance and maximises results, especially during the first few weeks of treatment.
Step 1: Cleanser
Use a gentle, non-comedogenic cleanser morning and evening. Avoid harsh foaming cleansers or physical scrubs that can compromise the skin barrier.
Step 2: Skinoren
Apply to clean, dry skin after cleansing. Allow to absorb for 2–3 minutes before applying other products.
Step 3: Moisturiser
Choose a lightweight, non-comedogenic moisturiser. Especially important if you experience initial dryness or peeling.
Step 4: SPF (morning only)
A broad-spectrum SPF 30 or higher. Non-negotiable if treating PIH or melasma. Apply as the final step of your morning routine.
- Niacinamide (10%) — complements depigmenting and barrier-supporting effects
- Ceramides and hyaluronic acid — improve tolerance, especially during initial weeks
- SPF (daily, non-negotiable) — prevents UV-driven PIH worsening
- Benzoyl peroxide — use separately (e.g. BP wash in AM, Skinoren in PM)
Introduce gradually: Retinoids (tretinoin, adapalene, retinol) can be used alongside Skinoren, but introduce them on alternate nights initially to avoid compounding irritation. AHAs and BHAs should also be used sparingly at first.

Get Skinoren online →Frequently Asked Questions
What is Skinoren used for?
Skinoren is used to treat acne vulgaris, rosacea, post-inflammatory hyperpigmentation, and melasma. Its active ingredient, azelaic acid, reduces bacterial growth, normalises skin cell turnover, and inhibits melanin production — making it one of the few topical treatments that addresses both active spots and the dark marks they leave behind.
What is the difference between Skinoren cream and Skinoren gel?
Skinoren cream contains 20% azelaic acid in a thick, moisturising formulation suited to dry or sensitive skin. Skinoren gel contains 15% azelaic acid in a lighter, faster-absorbing formulation better suited to oily or combination skin. Both are equally effective for their licensed indications — the difference is primarily about texture and skin type compatibility.
How long does Skinoren take to work?
Most patients notice fewer new breakouts and reduced redness within four to six weeks of consistent twice-daily use. Maximum benefit for active acne is typically seen after 12 weeks. For hyperpigmentation and melasma, results may take up to six months.
Can I buy Skinoren online in the UK?
Yes. Skinoren is available to buy online through GPhC-regulated pharmacies such as Access Doctor. You complete a short online consultation with a GPhC-registered pharmacist independent prescriber and have Skinoren delivered to your door. Completing a consultation does not guarantee that treatment will be prescribed.
Is Skinoren safe during pregnancy?
Azelaic acid is generally considered one of the safer topical acne treatments during pregnancy, particularly in comparison to retinoids. Always discuss any treatment with your prescriber, GP, or midwife before using it during pregnancy or breastfeeding.
Does Skinoren bleach skin or clothing?
Unlike benzoyl peroxide, Skinoren does not bleach fabrics or hair. However, it can cause temporary lightening of skin beyond the intended treatment area if applied too broadly — particularly in patients with darker skin tones. Apply only to affected areas to minimise this risk.
Can Skinoren be used for dark spots and post-acne marks?
Yes. Skinoren is one of the most evidence-based topical treatments for post-inflammatory hyperpigmentation — the dark marks left after acne spots heal. It works by inhibiting tyrosinase, reducing melanin production in affected areas. It is less effective for atrophic (pitted) acne scars, which may require other interventions such as microneedling or chemical peels.
Is azelaic acid the same as Skinoren?
Skinoren is the branded name for a product containing azelaic acid as its active ingredient, manufactured by Bayer. Other brands include Finacea Gel (15%). The active mechanism is the same; the formulations and concentrations differ. Skinoren is the most widely recognised brand in the UK.
Can I use Skinoren with retinol or tretinoin?
Yes, but introduce these combinations gradually. Use retinoids on alternate nights initially, allow four to six weeks before using both in the same routine. Always use a broad-spectrum SPF 30+ each morning when using either product.
Who prescribes Skinoren at Access Doctor?
