Who qualifies

Hi-Doctor provides online consultations for adult patients experiencing mild to moderate inflammatory acne. Eligibility is determined strictly by the reviewing physician based on your medical history and uploaded photographs.

Who qualifies

Duac is indicated for acne characterised by inflammatory papules and pustules. Because benzoyl peroxide prevents bacterial resistance, Duac is frequently prescribed for individuals who require short-term antibacterial action without using oral antibiotics.

Please note that online care is strictly topical. Oral isotretinoin, oral antibiotics, and severe, nodular, cystic, or scarring acne are out of scope and require an in-person referral.

What Duac actually does

Duac combines two synergistic active ingredients: clindamycin 1% (a lincosamide antibiotic) and benzoyl peroxide (3% or 5%, an oxidising keratolytic agent). Clindamycin suppresses the proliferation of Cutibacterium acnes, reducing inflammatory mediator release in the follicle. Benzoyl peroxide introduces free-radical oxygen into the sebaceous unit, killing bacteria and promoting desquamation.

More than 50,000 patients have used Hi-Doctor for professional medical consultations, supported by a 4.8 Trustpilot rating.

Because benzoyl peroxide exerts an oxidising antibacterial effect, Cutibacterium acnes cannot readily develop resistance against it. This crucial synergy protects clindamycin, which is why clindamycin is never prescribed as monotherapy for acne. Treatment is applied once nightly and is strictly capped at a maximum duration of 12 weeks to minimise resistance and skin irritation.

Skin purging and mild irritation are common during weeks 2 to 6. Meaningful clinical improvement is judged at 12 weeks, not before.

Side effects and when to stop

Most side effects from Duac occur locally at the application site during the initial weeks of therapy. You may experience mild erythema, peeling, dryness, and a temporary burning or stinging sensation.

Benzoyl peroxide bleaches hair, fabrics, towels, and clothing on contact. Wash your hands thoroughly after application and allow the gel to dry completely before coming into contact with bedding.

Stop using Duac immediately and consult a healthcare professional if you experience severe contact dermatitis, facial swelling, blistering, or persistent abdominal cramps and watery diarrhoea (an extremely rare complication associated with clindamycin absorption).
