Buy Duac Once Daily Gel
Duac Once Daily Gel is a topical medication that treats acne by reducing whiteheads and blackheads and preventing the growth of bacteria.
It is suitable for those with mild to moderate acne.
How Duac Once Daily Gel works
Duac Once Daily Gel contains two active ingredients: clindamycin and benzoyl peroxide.
Clindamycin is a topical antibiotic that kills the bacteria trapped in the pores that cause acne.
Benzoyl peroxide helps break down the top layer of skin, increasing cell turnover and shedding dead skin cells that block the pores.
Directions
Always use Duac Once Daily Gel exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you.
This product should be used once a day in the evening.
Completely remove makeup and wash the affected area of skin. Rinse your skin with warm water and gently pat dry. Apply a thin layer of gel onto the affected area, then gently massage it into the skin using your fingertips.
Use a fingertip-sized amount if you’re using it only on your face.
Don’t apply too much or exceed the recommended dosage; this will not help your acne clear up quicker and may cause some skin irritation.
It could take around 2-5 weeks to see a noticeable improvement in your acne. You shouldn’t use Duac for more than 12 weeks at a time. Always follow your doctor or Chemist4U pharmacist’s advice on how long your treatment should last.

Weird causes of acne
What causes acne?
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
