Treclin Gel

Treclin Gel is a prescription-only topical treatment that combines two powerful active ingredients: the antibiotic clindamycin and the retinoid tretinoin. It is designed to treat acne vulgaris in patients aged 12 years and over by tackling both the bacterial infection and the underlying skin cell clogging that leads to spots. It works by reducing inflammation, preventing new blockages (comedones), and promoting skin renewal.

What is Treclin Gel?

Treclin Gel is a prescription-only topical medication containing two active ingredients: clindamycin phosphate (an antibiotic) and tretinoin (a retinoid, a form of vitamin A). This combination treatment is specifically formulated to address multiple aspects of acne simultaneously.

Mechanism of Action

Treclin Gel works through a dual-action mechanism that targets both the bacterial and structural components of acne:

  • Clindamycin (The Antibiotic): Penetrates into pores and inhibits the growth of acne-causing bacteria (Cutibacterium acnes), reducing inflammation and preventing new inflamed spots from forming.
  • Tretinoin (The Cell Regulator): Normalises the lifecycle of skin cells lining hair follicles, preventing them from clumping together and forming pore blockages. It also helps expel existing plugs (comedones).

Think of acne as a two-part problem: 1) pores getting clogged with dead skin cells and oil, and 2) bacteria thriving in these clogged pores causing inflammation. Treclin tackles both problems at once, making it more effective than single-ingredient treatments.

What is Treclin Gel Used For?

Treclin Gel is indicated for the topical treatment of acne vulgaris according to NHS treatment guidelines.

Treclin Gel (Clindamycin & Tretinoin) FAQs

No. Treclin Gel is strictly contraindicated during pregnancy and if you are planning a pregnancy. The tretinoin component can cause birth defects. Effective contraception must be used during treatment and for one month after stopping. Always consult your doctor before starting any acne treatment if there's any possibility of pregnancy.

It may take several weeks (often 6-12 weeks) to see optimal improvement. According to NHS prescribing guidelines, topical acne treatments typically show initial results within 4-8 weeks with maximum benefit at 12 weeks. Do not stop using it if you don't see immediate results. An initial "purge" or flare-up can sometimes occur as the gel unclogs pores.

Yes, but apply Treclin first to clean, dry skin at bedtime. Let it absorb fully (wait 20-30 minutes). You can use non-comedogenic moisturisers and makeup during the day. Avoid applying other products directly on top of Treclin at the same time. Look for products labeled "oil-free" or "non-comedogenic" to avoid further pore clogging.

This is a common sign of irritation or overuse. Gently wash your face with a mild soap and lukewarm water, and stop using Treclin until your skin has healed (usually 2-7 days). When restarting, use a smaller amount or apply every other night as advised by your doctor. Use a gentle, fragrance-free moisturiser to help repair your skin barrier.

Yes, it is essential. Treclin (especially the tretinoin) makes your skin more sensitive to UV rays. Use a broad-spectrum sunscreen with SPF 30 or higher every day, even when cloudy, and wear protective clothing/hats. Choose oil-free, non-comedogenic sunscreens specifically formulated for acne-prone skin.

It's recommended to use Treclin at bedtime. Tretinoin can break down in sunlight, reducing its effectiveness. Nighttime application also allows the medication to work while you sleep and minimizes sun exposure. If you must apply during the day, use strict sun protection and avoid direct sunlight.

This "purging" phase is common in the first 2-6 weeks. As tretinoin unclogs pores, it brings existing microcomedones (tiny blockages) to the surface faster, which can temporarily increase breakouts. This usually subsides within 4-8 weeks as your skin adjusts. Continue treatment unless irritation is severe.

Not at the same time. Benzoyl peroxide can inactivate clindamycin. If you need to use both, apply benzoyl peroxide in the morning and Treclin at night, or use them on alternate days. Always consult your doctor before combining acne treatments, as this can significantly increase irritation.

Topical clindamycin has lower risk of systemic antibiotic resistance than oral antibiotics. However, to minimize risk: use only as prescribed, don't use for longer than recommended (usually 3-6 months continuously), and don't use it for non-acne conditions. Combining with benzoyl peroxide (at different times) can further reduce resistance risk.

Treatment duration varies by individual. Many use it for 3-6 months initially, then may reduce to maintenance use (2-3 times weekly) or switch to tretinoin-only products. Regular review with your doctor is important. Long-term antibiotic use should be monitored to minimize resistance risk.

The shelf life after first opening is 3 months. Write the opening date on the tube. Discard after this time as the medication may lose effectiveness. Store at room temperature (below 25°C) with cap tightly closed to prevent drying out.

Alternatives include: topical retinoids alone (tretinoin, adapalene), topical antibiotics alone (clindamycin), benzoyl peroxide, azelaic acid, or combination products like Epiduo (adapalene + benzoyl peroxide). Oral treatments like antibiotics, hormonal therapies, or isotretinoin may be considered for more severe cases. Consult a dermatologist for personalized recommendations based on your acne type and severity.
