The powerful double action of Duac’s active ingredients can help you to overcome your acne struggles, clearing the infection from within and bringing back your natural skin tone and texture.

Once you have received your prescription you can purchase Duac online and it will be sent to you by next day delivery where possible.

  • dryness
  • itching
  • redness
  • mild peeling of the skin

How effective is Duac?

Duac contains two powerful active ingredients called clindamycin phosphate and benzoyl peroxide. Together they are designed to effectively treat the bacterial infection by breaking down the comedones, the black and white heads, which will in turn unblock the glands.

The two ingredients, when working together, are known to be highly effective in dealing with acne with 50% of blemishes clearing up in as little two weeks in some cases where Duac is applied. It has also been shown to remove nearly double the number of blemishes than it’s closest acne-fighting competitor, and 10% more by the end of the first month of use.

Why choose Duac?

Duac is a popular choice because it only needs to be applied once a day making it an easy treatment to use. It is also preferable for anyone who does not wish to take tablets as the skin is still getting the benefit of an antibiotic without the need to swallow a pill.

Another reason for its popularity is that together, the ingredients can remove nearly all acne bacteria on the skin, clearing it up and easing the discomfort of outbreaks in a matter of weeks. In fact, clindamycin, the antibiotic contained in Duac, is the number one antibiotic used for clearing up acne in the UK. One major reason for this is that the other antibiotic sometimes prescribed for acne can stain teeth whereas Clindamycin does not.

What is contained in Duac?

Duac is a gel which contains two active ingredients; an antibiotic designed to kill the bacteria causing the acne called clindamycin and an acne-fighting antiseptic called benzoyl peroxide.

How should I take Duac?

Duac is designed to be used once a day, in the evening. It is important to wash the skin with a mild cleanser before applying the gel to ensure the skin is as clean as possible.

The treatment must be applied in a thin layer to all affected areas of the skin rather than only on specific spots.

It is important to apply sparingly. If the gel is difficult to rub in you have used too much.

How does Duac work?

Clindamycin is widely used to fight many bacteria based infections including Propioni bacterium acnes, the bacteria which feeds on the sebum produced within the skin’s sebaceous glands. This bacteria produce fatty acids and waste products which begin to irritate the glands causing them to become inflamed and erupt into acne-like spots. The application of clindamycin controls the number of bacteria able to survive on the skin, thus stopping the irritation and inflammation and allowing the skin to heal.

The medication fighting alongside the antibiotic in Duac is benzoyl peroxide which is a keratolytic, a medicine designed to break down the protein forming part of the structure of the skin known as keratin. The application of this antiseptic breaks down skin cells causing them to shed and break down the comedones, also known as blackheads and whiteheads, with it. This then clears the sebaceous glands which means fewer comedones can be formed.

Duac gets to work in as little 48 hours with the clindamycin killing bacteria which causes the acne, and then, any bacteria left behind is then cleared up by the antibacterial benzoyl peroxide.
