Dual Daily Gel, is a popular and effective topical treatment for acne. It has two ingredients to help battle acne in two ways.

Clindamycin – Clindamycin is an antibiotic and is perhaps the most commonly used antibiotic for acne.
Benzoyl peroxide – This works to removing blockages of excess sebum from the skin pores. In addition, benzoyl peroxide also has an anti-bacterial action.

You can also purchase other antibiotic based acne treatments such as Lymecycline and Zineryt or retinoid based treatments such as Differin and Epiduo gels.


How Is Duac Applied?

The gel is usually applied to the affected area in the evening, after washing your face. Remember when washing your face, you should use warm water, and ideally an oil free acne wash. Patting your skin dry is also preferable, as this is less irritating to your skin. Following washing, apply duac thinly over all affected areas with your fingertips.

What is Duac?

Duac is a dual action treatment gel for acne. It contains clindamycin (an antibiotic), and benzoyl peroxide (a peeling agent). These active ingredient works to reduce the number of bacteria on the skin, responsible for acne. Benzoyl peroxide also helps to unblock pores. Blocked pores can often result in painful, red zits.

When should I use Duac?

If your acne has not responded to antibiotics or peeling agents alone, then Duac combines both, to provide a second line of treatment to more resistant acne.

How long will it take Duac to work?

This can vary, however most people will see results within 4-5 weeks. It may take upto 12 weeks for some people however. Most acne treatments take time for you to see the full benefits due to the shedding cycle of your skin.

What are the side effects of Duac?

The most common side effect of Duac is dry, red or sore skin. This is because Benzoyl Peroxide has a drying effect on the skin. If inflammation and dryness is severe, you should reduce the application frequency to once every two days. If you are still suffering from sever dry / red skin, you should stop using this treatment.
You may also notice you have increased sensitivity to light. Wearing protective clothing / sunscreen is recommended if you notice your skin is more sensitive to sunlight

Can I use Duac gel more than once daily?

No there has not been any convulsive evidence to suggest that using Duac Gel twice daily will clear acne more effectively. Overuse is likely to result in skin dryness and irritation, and may lead to antibiotic resistance.

Can I apply more Duac Gel?

No there is no evidence to suggest that applying more Duac gel (i.e. not thinly) will improve acne treatment and can lead to resistance.

How long does it take for Duac gel to start working?

Most people will see an effect within 2 to 6 weeks of using Duac gel consistently.
