How it works

How Treclin works in the body

  1. Normalises follicular keratinisation

    Tretinoin (all-trans retinoic acid) binds retinoic acid receptors and reduces abnormal keratinocyte cohesion inside the follicle — which is the earliest lesion (microcomedone) in acne.

  2. Kills acne bacteria

    Clindamycin is a topical lincosamide antibiotic active against Cutibacterium acnes, the bacteria driving inflammatory acne lesions (papules, pustules).

  3. Two pathways, one topical

    Retinoid-driven comedolysis and antibiotic-driven anti-inflammatory action address both the comedonal and inflammatory components of acne in a single application.

Clinical evidence

What the trial data shows

Peer-reviewed evidence for Treclin, cited and attributed — not reframed as a personal promise.

Randomised controlled trial

Dréno et al. — tretinoin/clindamycin vs monotherapies

Dréno B et al., Journal of the European Academy of Dermatology and Venereology, 2014;28(10):1285–1292

Participants
1,710
Duration
12 weeks
Comparator
Tretinoin alone, clindamycin alone, vehicle

In patients with moderate-to-severe acne, tretinoin 0.025% / clindamycin 1.2% combination produced greater reductions in total, inflammatory, and non-inflammatory lesion counts than either monotherapy and vehicle over 12 weeks. Trial results do not predict individual outcomes.

Meta-analysis / systematic review

Leyden et al. — combination topical meta-review

Participants

Duration
Meta-analysis (pooled)
Comparator
Monotherapies, vehicle

Pooled data across multiple trials supports fixed-combination topical retinoid + antibiotic as more effective than monotherapy, with benzoyl peroxide sometimes added to reduce antibiotic resistance pressure.

Trial results do not predict individual outcomes. Your pharmacist will discuss realistic expectations during consultation.

Dosing

Typical dosing schedule

Doses escalate gradually under pharmacist supervision to support tolerability. Your exact plan is set during your consultation.

Typical Treclin dose escalation schedule
WeekNotes
Daily

Pea-sized amount to affected areas, once at night

Apply to cleansed, dry skin. Avoid eyes, lips, nasal folds, and damaged skin. Daily broad-spectrum SPF 30+ is essential — retinoids increase UV sensitivity.

Weeks 1–4

Continue nightly

A temporary flare ('retinoid purge') in weeks 2–4 is expected. Mild dryness, peeling, or stinging is common and usually improves with a bland moisturiser.

Weeks 8–12

Pharmacist review

UK guidance recommends reviewing antibiotic-containing topical therapy at 12 weeks. Your pharmacist may step you down to tretinoin alone, or swap to a BPO-based combination to limit antibiotic resistance.

Safety profile

Possible side effects

Grouped by frequency. Your pharmacist will review these with you in detail before you start.

Common
  • Skin dryness, peeling, or erythema (typical first 4 weeks)
  • Mild burning or stinging on application
  • Increased sensitivity to sunlight (UV)
  • Temporary flare in weeks 2–4 ('retinoid purge')
Uncommon
  • Contact dermatitis or worsening erythema
  • Photosensitivity reaction
  • Eyelid irritation (avoid application near eyes)
Rare
  • Severe allergic reaction (stop and seek urgent medical advice)
  • Severe or persistent gastrointestinal symptoms (including bloody diarrhoea — rare with topical clindamycin but reported; seek urgent medical advice)

Not a complete list. Read the Patient Information Leaflet supplied with your medication. Report any suspected side effects to the MHRA Yellow Card scheme.

Eligibility

Is Treclin right for you?

Usually suitable for

  • Adults aged 18+ with moderate-to-severe mixed acne

Everything you need to know about Treclin

Find answers about treatment, safety and the service journey.

How does Treclin work?

It combines two complementary actions. Tretinoin (a topical retinoid) normalises how keratinocytes shed inside the follicle — reducing microcomedone formation. Clindamycin (a topical antibiotic) kills Cutibacterium acnes bacteria and reduces inflammation. Used once daily, the combination addresses both comedonal and inflammatory acne.

How long until I see a response?

Clinical response is typically assessed at 8–12 weeks. In weeks 2–4 you may notice a temporary flare as the retinoid clears microcomedones faster — this is expected and usually settles with continued use and a bland moisturiser.

How does this differ from Duac and Epiduo?

Duac is clindamycin + BPO (antibiotic-led). Epiduo is adapalene + BPO (retinoid + BPO). Treclin is tretinoin + clindamycin (retinoid + antibiotic). Your pharmacist picks the combination that matches your lesion type, tolerance, and antibiotic-stewardship considerations.

How much should I apply?

A pea-sized amount spread thinly across the affected areas, once a night. More is not better — over-application increases irritation without improving efficacy.

Is tretinoin the same as retinol?

No. Retinol is a cosmetic precursor that skin converts slowly into retinoic acid. Tretinoin IS retinoic acid — the active form — and it's a prescription medicine, much more potent than cosmetic retinol, with evidence of effect on acne at licensed strengths.

Will my acne come back if I stop?

Acne is a long-term condition. Recurrence is common when any topical treatment stops. UK guidance recommends continuing for several months after clearance and then stepping down under pharmacist review — typically to tretinoin alone or to a BPO-based combination for maintenance.

Why limit the duration to 12 weeks?

Because Treclin contains a topical antibiotic (clindamycin), UK guidance keeps antibiotic-containing topical therapy to the minimum effective duration — typically up to 12 weeks — to reduce the risk of driving antibiotic resistance in skin flora.
