Acne: General information
Acne is a very common yet non-contagious skin condition that manifests through appearance of spots on the skin, most commonly on the face, back or chest. While almost everybody will experience acne at least once in their life, this condition generally tends to decrease in intensity and frequency of flare-ups as the years go by, eventually disappearing completely after puberty. However, in those people who still experience acne issues in their adult years, the severity of the condition can significantly vary. Some people struggle with so called whiteheads and blackheads, very small and usually scarce dots, while others are affected by much more serious forms of the condition characterised by painful pustules and cysts which leave scars after disappearing.
According to the NHS, roughly 80% of people aged between 11 and 30 years have been affected at least once by this condition. Those with milder forms can improve their condition by simply introducing a twice-daily cleansing routine, while others might have to rely on prescription treatments in order to keep their condition under control.
Acne is a somewhat complex condition – on one hand, its root cause is increased activity of skin’s sebaceous glands that synthesise and release sebum, an oily substance that is naturally produced by the body in order to protect skin and hair. When there is an excess of this substance, different types of bacteria will find their way into the skin where they will feed of sebum. However, the inflammation marked by pustules and cysts is actually caused by inflammation of sebaceous glands as a result of bacterial waste materials (fatty acids).
Acne treatment and management
A common mistake people make when they notice acne is squeezing them or using a lot of cosmetics to try and cover them up. However, both of these practices are actually rather harmful – while covering acne up will only contribute to further bacterial infection, squeezing them will leave permanent scars which can be detrimental for self-esteem of an individual. In most cases, acne symptoms will improve and gradually disappear as the time goes by, but in some cases, the condition can continue manifesting well into adulthood.
Treatments of acne are very varied and there are numerous different approaches which will act differently in different people. Unlike some other options, Duac once daily gel is actually a topically applied antibiotic. Duac relies on its two active ingredients, clindamycin and benzoyl peroxide in order to achieve its goal. So while the antibiotic component, clindamycin is killing off the bacteria that feed on sebum, a substance produced by skin’s sebaceous glands, while benzoyl peroxide, a keratolytic by classification, will encourage the top layer of skin to shed, thus reducing the number of spots visible and preventing their re-emergence.
How is Duac gel used?
In order to ensure the best possible results while at the same time minimizing the risk of unwanted side effects, it is highly advisable to carefully follow the instructions provided by your prescribed. If you are unsure about any aspect of the treatment, consult with your doctor or refer to the official patient information leaflet that is issued within every pack of the gel.
The most general guidelines can be described as follows:
- Use once daily, usually in the evening
