Buy Treclin Gel

Treclin is an acne treatment that is applied directly to the skin. It contains an antibiotic and a retinoid to reduce the appearance and uncomfortable symptoms of acne. It works by limiting the growth of bacteria that causes acne, reducing sebum (oil) production and reduces inflammation. This treatment is suitable for adults and children aged 12 and over, but you will require a prescription. If you’re looking for an effective acne treatment, speak to one of our prescribers or fill in one of our quick consultation questionnaires to discover if Treclin Gel is suitable to treat your symptoms.


How Treclin Gel works to improve symptoms of acne

Treclin gel contains the active substances Clindamycin and Tretinoin. Clindamycin is an antibiotic which works by limiting the growth of bacteria associated with acne and inflammation. Tretinoin causes normal shedding of skin which clogs the hair follicles in areas with acne. This prevents build-up of oil (sebum) and the formation of spots such as blackheads and whiteheads. The effective formula is applied topically to the skin and is suitable for adults and children aged 12 and over.



Always use this medicine exactly as described by your doctor. The recommended dose is a pea-sized amount of Treclin applied once daily at bedtime.

  • Wash your face gently with mild soap and warm water and pat your skin dry with a towel.
  • Squeeze a pea-sized amount of gel onto the fingertip
  • Dab the gel on your forehead, chin, nose and both cheeks and then gently spread it evenly over your whole face

Do NOT use more than the amount that has been recommended by your doctor or apply the product more frequently than instructed. Too much medication may irritate the skin and will not give faster or better results.

What is Acne? Your Questions Answered

Spot break outs always seem to happen at the worst possible moment, just before a first date, the day you’re getting your photo taken, all of those wonderful occasions when you could really do with not having a huge spot between your eyes.

But do you just have a few spots, or are you suffering with acne?

Frequently Asked Questions

To get the best results with Treclin, it is necessary to use it correctly and to not stop using it as soon as your acne starts to get better.

It may typically take several weeks to have an optimal effect. In some cases, it may take up to 12 weeks.

Please contact your doctor if your symptoms persist after 12 weeks.

Acne can be caused by a variety of reasons, but the most common cause is a change in hormone levels.

This is why acne is most common in teenagers, during pregnancy, and at different times during your menstrual cycle.

Hormonal changes can cause the glands next to hair follicles to produce more oil (sebum) than normal, which can change the activity of a normally harmless bacterium to become aggressive and cause inflammation and pus.

Acne can cause different types of spots to develop on the face, back and chest including:

  • Blackheads: bumps that are small and black or yellowish in colour
  • Whiteheads: similar to blackheads, but may be firmer and won’t be empty when squeezed
  • Papules: small red bumps that may feel tender or sore
  • Pustules: similar to papules, but with a white tip in the centre that is caused by a build-up of pus
  • Nodules: large hard lumps that can be painful
  • Cysts: large pus-filled lumps that look similar to boils and carry the greatest risk of causing permanent scarring

You do need a prescription for this medication in the UK.

Our healthcare professionals can provide prescriptions if they think this treatment would be right for you and your condition.

When you click the button which reads “Start Consultation” at the top of this page, you’ll see a short questionnaire set up by our healthcare team which is designed to help them understand your medical needs.

Just like an in-person consultation with your GP, our doctors will assess your answers to their questions and write a prescription for the treatment they think will be best for you.

You’ll then be able to pay for your medication and we’ll send it out to you quickly and in discreet packaging.
