How it works — get your consultation in 4 steps

The consultation process is completely online, asynchronous, and GDPR-compliant. You do not need to attend a clinic, sit in a waiting room, or join a video call.

1. Fill out the medical questionnaire: Answer questions about your acne history, affected facial or body zones, previous treatments, and overall health.
2. Upload skin photographs: Provide clear, well-lit photos of your skin so the EU-licensed doctor can assess lesion morphology and severity accurately.
3. Doctor review: A doctor evaluates your clinical profile and photos within 24 hours to determine if topical treatment is medically appropriate.
4. Receive your REMPE prescription: If approved, your REMPE prescription PDF is delivered straight to your secure Hi-Doctor account inbox and notified by email.

Who qualifies

To get Duac online, you must be at least 18 years old and present with mild-to-moderate inflammatory acne. This presentation is typically marked by superficial papules, pustules, and comedones across the face, chest, or back.

Hi-Doctor provides topical acne treatments only. Patients with severe, nodulocystic, conglobate, or scarring acne do not qualify for this online pathway and are referred to in-person dermatologists. Hi-Doctor does not prescribe oral isotretinoin (Roaccutane), oral antibiotics, or hormonal therapies online, as these medications mandate physical examinations and ongoing laboratory blood tests.

What Duac actually does

Duac is a prescription topical gel combining clindamycin 1% and benzoyl peroxide (3% or 5%). Each active component tackles inflammatory acne through a distinct physiological pathway:

• Clindamycin 1%: A lincosamide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit of Cutibacterium acnes, reducing inflammatory lesion counts.
• Benzoyl peroxide (3% or 5%): A potent oxidising agent that releases free oxygen radicals to rapidly destroy C. acnes without provoking bacterial resistance, alongside delivering mild comedolytic activity.

The benzoyl peroxide component is what prevents Cutibacterium acnes from developing resistance to clindamycin, which is why clindamycin is never prescribed as a monotherapy. Duac gel is applied once daily in the evening to clean, dry skin. To prevent microbial resistance, treatment duration is strictly capped at 12 weeks.

Topical Therapy	Active Ingredients	Application Regimen	Clinical Focus
Duac Gel	Clindamycin 1% + Benzoyl Peroxide 3% or 5%	Once nightly (capped at 12 weeks)	Mild-to-moderate inflammatory acne
Epiduo / Acniduo	Adapalene 0.1% + Benzoyl Peroxide 2.5%	Once nightly	Comedonal and inflammatory acne
Skinoren / Finacea	Azelaic Acid 15%	Twice daily	Sensitive skin, hyperpigmentation, pregnancy

Transient retinoid purging or localized skin adjustment can happen in weeks 2 to 6 of topical therapy. Meaningful clinical change is judged at 12 weeks, not before.

Side effects and when to stop

Common local reactions to Duac include erythema, skin peeling, dryness, burning, and stinging at the application site. Benzoyl peroxide also bleaches coloured hair, fabrics, and bed linen on contact.

You should discontinue treatment immediately and seek in-person medical care if you develop severe contact dermatitis, facial swelling, breathing difficulties, or persistent severe abdominal cramps with watery diarrhoea (a rare marker of systemic clindamycin absorption and pseudomembranous colitis).
