However, it is advisable to consult a dermatologist, even for early or mild symptoms, as medicinal intervention can help to prevent further aggravation and consequences such as scarring.

These cleanse, clear and care for impure and acne-prone skin. There are also a number of lifestyle changes sufferers can make to control outbreaks and minimise symptoms.

Signs & Symptoms

Signs & symptoms of impure and acne-prone skin

Before deciding which non-medicinal treatment to use, it’s important to identify the symptoms that are causing concern. Treatments for impure and acne-prone skin and mild to moderate acne tend to address one or more of the four issues attributed to the condition.

Acne: what happens in skin.

They work by:

  • reducing sebum production thereby controlling seborrhea.
  • speeding up skin cell shedding, and therefore helping to deal with hyperkeratosis.
  • fighting bacterial infection caused by microbial colonisation.
  • and may even reduce inflammation and, in turn, calm down spots, papules and pustules.

It is also important to differentiate between impure and acne-prone skin and hypersensitive skin reaction with pimples or rosacea. The papules and pustules that appear in the hypersensitive disorder Rosacea, for example, are similar in appearance to acne but there are no blocked pores, the skin is more likely to be dry than greasy and Rosacea spots don't leave scars.

Causes & Triggers

Major causes and triggers of impure and acne-prone skin

Seborrhoea
Microbial colonisation

Impure and acne-prone skin is a very common skin condition that usually begins during puberty when both boys and girls experience major hormone changes. Hormone substances, called androgens, stimulate sebaceous glands to produce more sebum than is necessary (seborrhea). This seborrhea may itself interfere also with the normal skin shedding.

When skin produces an excess amount of sebum and does not shed dead skin cells sufficiently, the two can build up in the hair follicle and form together as a soft plug. This plug may cause the follicle wall to bulge and produce a whitehead or, the plug may be open to the surface and may darken, causing a blackhead.

Pimples (also known as papules or pustules) are raised red areas of skin with a white centre that develop when blocked hair follicles become inflamed or infected. Blockages and inflammation that develop deep inside sebaceous glands produce lumps beneath the surface of the skin called cysts.


Impure skin is most commonly found on the face, shoulders, chest and back as these are the areas that produce the most sebum.

Especially teenagers should take a focus on a daily skin care routine as they are more prone to acne.

Hormones. Although most common in teenagers, there are increasing numbers of adults with impure and acne-prone skin, particularly women who experience hormonal changes during pregnancy, menstruation or as a result of a hormone-related condition such as polycystic ovary syndrome.

Bacteria. Acne-prone skin tends to be quite oily as a result of the excessive sebum secretion. This makes it more prone to bacterial overgrowth of the usually harmless bacteria that live on the skin. These cause irritation and inflammation to the enlarged sebaceous glands.

Normally harmless acne bacteria (Propionibacterium acnes) can multiply due to excessive production of sebum.

Genetics. There is some evidence that genetic predisposition plays a large part in the development of acne. If both parents suffered from acne during their adolescence, then the likelihood is great that their children will also develop acne. In the same vein, the children of adult acne sufferers are more likely to develop adult acne themselves.

Myths of acne-prone skin

Exaggerated washing may worsen acne symptoms.
Eating sweet products containing sugar can worsen your acne symptoms.

As well as the facts, there is a lot of fiction surrounding the causes of acne-prone skin. These unfounded myths unfairly blame the sufferer for their condition. For example, people with acne-prone skin are often told that they are unhygienic or do not wash their skin often enough. The truth is that over-washing is actually more damaging to acne-prone skin than under-washing as skin can become more irritated by excessive rubbing. Sufferers are also accused of having a poor diet.

While a healthy diet is always preferable, there is little evidence to show that greasy foods or chocolate exacerbate symptoms.

Contributing Factors

The main contributing factors of acne-prone skin

While the main causes of acne-prone skin tend to be hormonal or genetic, there are some further factors that have been shown to aggravate the symptoms. For example:

Excessive drinking of milk can aggravate the symproms of acne.

  • a diet rich in certain carbohydrates
  • excessive drinking of milk and other dairy products 
  • cigarette smoking
  • heavy or comedogenic skin care products and make-up which is known to block pores

Touching pimples make things worse. Consult a professional cosmetician.

  • Use lukewarm water rather than over-hot or over-cold.
  • Use non-comedogenic make-up.
  • Only use non-comedogenic skin care.
  • Use sun protection tailored to the needs of oily and acne-prone skin.
  • Leave pimples alone – touching or squeezing them will only make things worse.
