Acne – causes , symptoms, treatments and myths.

Acne is a common skin condition that affects most people at some point. It causes spots to develop on the skin, usually on the face, back and chest.

The spots can range from surface blackheads and whiteheads – which are often mild – to deep, inflamed, pus-filled pustules and cysts, which can be severe and long-lasting and lead to scarring.

What can I do if I have acne?

Keeping your skin clean is important, but will not prevent new spots developing. Wash the affected area twice a day with a mild soap or cleanser, but do not scrub the skin too hard to avoid irritating it.

If your skin is dry, use a moisturiser . Most of these are now tested so they don’t cause spots (non-comedogenic).

Although acne can’t be cured, it can be controlled with treatment. Several creams, lotions and gels for treating spots are available at pharmacies.

If you develop acne, it’s a good idea to speak to your pharmacist for advice. Products containing a low concentration of benzoyl peroxide may be recommended, but be careful as this can bleach clothing.


If your acne is severe or appears on your chest and back, it may need to be treated with antibiotics or stronger creams that are only available on prescription.

When to see your GP

See your GP if you cannot control your acne with over-the-counter medication or if it is causing you distress and making you feel unhappy.

Also see your GP if you develop nodules or cysts, as they will need to be treated properly to avoid scarring.

Treatments can take up to three months to work, so don’t expect results overnight. Once they do start to work, the results are usually good.

Try to resist the temptation to pick or squeeze the spots as this can lead to permanent scarring.

Why do I have acne?

Ehlers-Danlos syndrome.
Ehlers-Danlos syndrome.

Acne is most commonly linked to the changes in hormone levels during puberty, but can start at any age.

It affects the grease-producing glands next to the hair follicles in the skin. Certain hormones cause these glands to produce larger amounts of oil (abnormal sebum).

This abnormal sebum changes the activity of a usually harmless skin bacterium called P. acnes, which becomes more aggressive and causes inflammation and pus.

The hormones also thicken the inner lining of the hair follicle, causing blockage of the pores (opening of the hair follicles). Cleaning the skin does not help remove this blockage.

Acne is known to run in families. If both your mother and father had acne, it is likely that you will also have acne.

Hormonal changes, such as those that occur during the menstrual cycle or pregnancy, can also lead to episodes of acne in women.

There is no evidence that diet, poor hygiene or sexual activity play a role in acne.

Who is affected?

Acne is very common in teenagers and younger adults. About 80% of people between the ages of 11 and 30 will be affected by acne.

Acne is most common between the ages of 14 and 17 in girls, and boys between 16 and 19.

Most people have acne on and off for several years before their symptoms start to improve as they get older. Acne often disappears when a person is in their mid-twenties.

In some cases, acne can continue into adult life. About 5% of women and 1% of men have acne over the age of 25.

Acne myths

Despite being one of the most widespread skin conditions, acne is also one of the most poorly understood. There are many myths and misconceptions about it:

  • “Acne is caused by a poor diet.” So far, research has not found any foods that cause acne. Eating a healthy, balanced diet is recommended because it is good for your heart and your health in general.
  • “Acne is caused by having dirty skin and poor hygiene.” Most of the biological reactions that trigger acne occur beneath the skin, not on the surface, so the cleanliness of your skin will have no effect on your acne. Washing your face more than twice a day could just aggravate your skin.
  • “Squeezing blackheads, whiteheads and spots is the best way to get rid of acne.” This could actually make symptoms worse and may leave you with scarring.
  • “Sexual activity can influence acne.” Having sex or masturbating will not make acne any better or worse.
  • “Sunbathing, sunbeds and sunlamps help improve the symptoms of acne.” There is no conclusive evidence that prolonged exposure to sunlight or using sunbeds or sunlamps can improve acne. Many medications used to treat acne can make your skin more sensitive to light, so exposure could cause painful damage to your skin, not to mention increase your risk of skin cancer.
  • “Acne is infectious.” You cannot pass acne on to other people.

Vitamin A- what it is what it does and why we need it for health?


RAF Lady Poster WW2When I was at school we were told that during the Second World War British military intelligence put about the rumour that RAF pilots ate carrots to improve their eyesight.  This was the reason that the RAF was so successful during the Battle of Britain.  Whereas, of course, the real reason was the British had developed radar and did not want the Germans to find out.    But in fact carrots, it now seems, are good for the eyes (especially for night vision).  And this is because of because of vitamin A. In fact this is the second in our series of blogs about vitamins and their role in a healthy lifestyle.

Our first blog looked at vitamin D – you can read it at http://patienttalk.org/?p=300. Before we go into more detail it is worth saying that while Vitamin A has a wide variety of functions in our bodies that main danger of Vitamin A deficiency is to our vision.  It has been estimated that between 250,000-500,000 children may go blind because of a lack of Vitamin A.  A related feature of  Vitamin A deficiency is night blindness or Nyctalopia.  This means that the patient has difficulty adjusting their sight when darkness falls.

But there are many other things that Vitamin A brings to the health party than just improved vision.  Among many things it is used by our bodies to:-

a)      Form blood cells

b)      Treat acne and is generally good for the skin.

c)       Help foetal development during pregnancy and is good for breast milk production.

d)      Boost the immune system

e)      Has an antioxidant function.  For more information on antioxidants please have a look at our previous blog on the subject – http://patienttalk.org/?p=252

To make sure you get adequate Vitamin A there are a number of different foods to look out for:- a)      Carrots

b)      Green leafy vegetables such as kale and spinach.

c)       Milk and Eggs

d)      Liver but especially cod liver oil.

e)      Tomatoes

And good news for me is that Sweet potatoes come highly recommended. It is worth bearing in mind that carrots, if taken to excess, have an interesting side effect.  They can turn you orange.  Or so the old wives tale goes.
