Description
Treclin Gel 30g is a prescription topical acne treatment for adults and adolescents aged 12+ with mild to moderate acne vulgaris. It combines clindamycin (an antibiotic) and tretinoin (a retinoid) to reduce acne‑associated bacteria and inflammation while helping keep pores clear to prevent new breakouts. Used correctly once daily in the evening, Treclin can improve spots, blackheads and whiteheads over time.

How Treclin Works
Treclin uses a dual‑action approach to acne:
- Clindamycin reduces acne‑associated bacteria and inflammation within clogged pores.
- Tretinoin increases skin cell turnover and helps prevent pore blockages (comedones), reducing blackheads and whiteheads.
- Using an antibiotic with a retinoid can improve inflammatory acne while helping prevent new lesions forming.
How to Use Treclin Gel (Once‑Daily Night Routine)
Apply Treclin once daily in the evening to clean, dry skin. Use a thin layer over the affected area not only on individual spots.
Step‑by‑step application
- Wash with a gentle cleanser and pat dry.
- Wait 20–30 minutes after washing (dry skin reduces irritation).
- Apply a thin film to the acne‑affected area once daily in the evening.
- Avoid eyes, lips, nostrils, mucous membranes, and broken/eczema‑affected skin.
- Wash hands after applying.
If irritation happens
- Mild redness, dryness, peeling or stinging can occur in the first weeks.
- Use a non‑comedogenic moisturiser and consider applying every other night for 1-2 weeks, then increase to nightly if tolerated.
- Use SPF 30+ daily and avoid sunbeds (tretinoin increases sun sensitivity).
Warnings & Precautions
- Do not use during pregnancy. If you become pregnant while using Treclin, stop and seek medical advice.
- Avoid applying to sunburned, cut, or irritated skin.
- Avoid waxing on treated areas (risk of skin lifting/irritation).
- Seek urgent advice if you develop severe, persistent diarrhoea, abdominal cramps, or blood/mucus in stool (rare risk with topical clindamycin).
- Benzoyl peroxide is not in Treclin, so it won’t bleach fabrics but tretinoin can still increase irritation with harsh products.
What to avoid while using Treclin
- Harsh scrubs, abrasive cleansers, alcohol-based toners
- Strong acids/exfoliants (AHA/BHA) unless a clinician advises spacing
- Other topical retinoids at the same time unless advised
Treclin Gel Side Effects
Common side effects are usually local skin reactions, especially early on:
- Dryness, peeling, redness
- Burning or stinging sensation
- Itching
- Increased sun sensitivity
Stop and seek urgent medical help if you develop signs of a serious allergic reaction (swelling, breathing difficulty).

FAQs
- Can I use Treclin on blackheads and whiteheads?
Yes. Tretinoin helps prevent clogged pores, which can reduce comedones (blackheads and whiteheads).
- Can I wear moisturiser and makeup with Treclin?
Yes. Use a non‑comedogenic moisturiser to reduce dryness. Apply makeup after the gel has absorbed.
- Can I use Treclin with other acne products?
Some combinations increase irritation. A clinician can advise a schedule (for example, spacing actives on different nights).
- What if I miss a dose?
Apply the next dose at the usual evening time. Do not apply a double dose.
- How long can I use Treclin for?
Courses are usually limited (often around 10-12 weeks). Follow your prescriber’s advice to reduce antibiotic resistance risk.
