How it works — get your consultation in 4 steps

Acquiring prescription acne treatment in Cologne does not require sitting in a clinic waiting room. The clinical assessment takes place entirely through an asynchronous questionnaire evaluated by registered EU physicians.

1. Complete the questionnaire: Fill in your medical history, current skin symptoms, and past treatments.
2. Upload clear photos: Provide well-lit images of the affected skin areas so the doctor can assess lesion types and inflammatory severity.
3. Clinical evaluation: An EU doctor reviews your submission and, when clinically appropriate, issues an electronic prescription within 24 hours.
4. Receive your REMPE PDF: Download the official Spanish REMPE private prescription PDF from your account to present at a local pharmacy in Cologne or elsewhere in the EU.

Who qualifies

Duac is a prescription-only topical therapy intended for inflammatory acne vulgaris. An EU-licensed doctor evaluates your questionnaire and images to determine whether topical combination therapy is medically indicated for your skin.

• Mild to moderate inflammatory acne: Patients with active papules and pustules qualify for topical evaluation.
• Adults and adolescents: Suitable for individuals aged 12 and older without hypersensitivity to lincosamide antibiotics or benzoyl peroxide.
• Patients requiring topical care only: Hi-Doctor handles topical dermatology pathways exclusively.

Severe nodulocystic acne, extensive scarring, and conditions requiring oral antibiotics or oral isotretinoin are strictly out of scope. Hi-Doctor does not prescribe oral acne treatments online; patients with severe disease are referred to in-person medical care.

What Duac actually does

Duac gel combines two active ingredients: clindamycin (1%) and benzoyl peroxide (3% or 5%). Clindamycin is a lincosamide antibiotic that halts the synthesis of bacterial proteins, suppressing Cutibacterium acnes proliferation inside the pilosebaceous unit.

Benzoyl peroxide acts as a potent oxidising agent with keratolytic and antibacterial properties. Its presence actively prevents C. acnes from developing resistance to clindamycin, which is why clindamycin is not prescribed as a standalone topical monotherapy. Clinical courses of Duac are capped at a maximum of 12 continuous weeks to minimise resistance risks.

Topical Option	Active Ingredients	Application Regimen	Clinical Focus
Duac Gel	Clindamycin 1% + Benzoyl Peroxide 3% or 5%	Once nightly (capped at 12 weeks)	Targeted reduction of inflammatory papules and pustules.
Epiduo / Acniduo	Adapalene 0.1% + Benzoyl Peroxide 2.5%	Once nightly	Dual comedolytic and antibacterial treatment for long-term control.
Skinoren / Finacea	Azelaic Acid 15%	Twice daily	Antibacterial and anti-inflammatory, suitable during pregnancy.

Expect a standard clinical timeline when beginning topical acne therapy. Initial skin irritation or mild purging can appear in weeks 2 to 6, while meaningful therapeutic changes are judged at 12 weeks of consistent application.

Side effects and when to stop

Localised skin reactions are common during the initial weeks of Duac therapy. You may experience erythema (redness), dryness, peeling, a burning sensation, or increased sensitivity to UV light.

• Apply a non-comedogenic moisturiser: Mitigate peeling and barrier dryness by layering a gentle moisturiser over dry skin.
• Use broad-spectrum sunscreen: Benzoyl peroxide increases photosensitivity; daily UV protection is necessary.
• Fabric contact: Benzoyl peroxide bleaches hair, towels, and clothing. Wash hands thoroughly after application.
• When to discontinue: Stop treatment immediately and seek emergency medical attention if you develop severe abdominal cramping, prolonged watery diarrhoea (signs of antibiotic-associated colitis), or signs of an acute allergic reaction such as facial swelling or difficulty breathing.
