Acne is a very common skin condition characterised by the appearance of spots and pimples on and around the face. It is mostly found in adolescents, but around a fifth of acne cases occur in the adult population.
The most common, and most visible, outbreaks of acne are on the face, but it’s also perfectly normal for the spots to appear on the neck, chest, shoulders, upper arms and the back. Acne in itself poses no risk to health, but severe cases can result in scarring if not dealt with carefully and effectively.
Acne is primarily caused by changes in hormone levels, which is why it is most common during teenage years, but can also be triggered by such hormonal fluctuations at any time of life. A common effect of high hormone levels is an increase in the oiliness of the skin, and this excess oil can clog up the pores and hair follicles leading to a growth in natural bacteria which can cause the spots to appear.
This process can be worsened by make up or skin irritants, which although they don’t cause acne directly, can make it harder for the skin to cope.
Many people think that acne spots are a sign of poor personal hygiene or dirty skin, but this isn’t the case. While it’s true that badly washed skin is more prone to spots of all kinds, acne is generally down to hormonal and hereditary factors, and obsessive washing of your face with ordinary soap will have little effect if you’re one of the people with a predisposition to the condition – in fact, scrubbing an affected area can actually make things worse by irritating your skin.
A good diet rich in fresh fruits and vegetables will generally improve your overall skin health, which may lessen the impact of acne, but diet is not proven to be a factor in actually developing the condition. Similarly, excess consumption of chocolate or other sweet foods will not in itself cause acne, although some people do have a mild allergic reaction to chocolate which can result in other kinds of spots appearing, but this is not directly related to acne.
Stress or anxiety is often mentioned as a cause of acne, and this does have some basis of truth. Although stress doesn’t directly result in skin problems, it can have a secondary effect through the changes in hormone levels it can cause, but again this only makes existing acne worse rather than specifically causing it.
Acne pimples can take many forms, covering most types of spots we’re familiar with, from those which are a nuisance but not a real cause for concern, to more severe skin lesions which can lead to scarring. These are the five main types of skin problems acne sufferers can experience, in order of severity:
These are simply clogged and blocked skin pores which have not become infected or too inflamed. The blockage is under the surface of the skin and hasn’t broken through, meaning that whiteheads remain more or less invisible but can be felt as small bumps in skin texture.
Blackheads are basically the same kind of pimple as a whitehead. The main difference is that the pressure of the blockage has broken through the pore’s surface, so that the top is exposed to the air – and this leads to a dark appearance of the spot.
Papules are blackheads or whiteheads which have become inflamed, and have swollen up into red bumps which are tender to the touch, or even painful. Despite the discomfort and obvious appearance, these papules are not yet infected, and with proper cleaning will usually heal of their own accord – definitely do not squeeze them, as this will only make things worse by risking infection.
These are the final result of some papules which have filled with pus, and are the classic image of a pimple that most people have in mind: small, hard, red bumps in the skin, painful to the touch, and with a yellow or white tip. Again, no matter how tempting it is, do not squeeze or pop these spots. Try and let nature take its course, leaving them to either fade away or burst on their own. Popping them only raises the risk of greater infection and thus permanent scarring.
These are the most serious types of acne pimples, and are large red lumps under the skin which can throb painfully and take a long time to disappear. More than ever, these types of pimples should never be squeezed – nodules and cysts are caused by bacteria under the skin, and trying to pop them will usually only push the bacteria deeper down, making the inflammation even worse.

Most people will suffer from acne at some point in their lives, especially during teenage years or at other times when hormone levels are in flux. It’s estimated that around 80% of people between the ages of 11 and 30 will experience at least one acne outbreak, although it’s far from unheard of for people to have an episode in their forties or even fifties. Acne can happen to people of all backgrounds, with no particular correlation to factors such as race or ethnicity.
Although the root causes of acne are the effects of hormone levels on the natural oils in the skin, there are several factors that can make an outbreak more severe and longer lasting. These include:
Many people say they find that their acne is worse if they eat too much chocolate or junk food, but in the majority of cases this is either a separate allergic reaction unrelated to acne, or it’s an effect caused by increased skin oiliness as a result of poor diet – this will be helped by the general acne skin care tips given at the end of this article.
For mild whiteheads and blackheads, treatment is available over-the-counter in the form of gels or creams containing benzoyl peroxide. You do not need a prescription to buy these treatments - your pharmacist will be able to help you choose. Benzoyl peroxide works as an antiseptic to reduce the number of whiteheads and blackheads on the skin by fighting bacteria and acting as an anti-inflammatory. It should be applied sparingly to the affected area once or twice a day. For most people, a 6-week course will clear or significantly reduce their acne, but you may choose to continue applying the treatment less regularly to prevent you acne returning.
Topical solutions are creams or gels which are applied directly to the parts of the skin affected by acne, and can work in various ways. Two of the most popular topical medications are Duac Gel and Differin Cream/Gel.
Duac Gel is a once-a-day, prescription-only treatment for mild to moderate acne. It contains two active ingredients that work on different aspects of acne, and is used for up to 12 weeks at a time. The first ingredient, clindamycin, is an antibiotic that works against the bacteria in the skin which contributes to the spots forming. The second ingredient is benzoyl peroxide, which helps to remove the dead cells from the surface of the skin, and clears out pore blockages. Duac gel should be applied thinly to the affected areas.
Differin is another topical treatment for acne, available in either cream or gel form, both of which require a prescription. It contains the active ingredient adapalene which is a form of vitamin A, and works against acne by reducing skin inflammation and helping to shed dead skin cells which can block pores, leading to spots. Like Duac, Differin is applied to the affected areas once a day after washing.
An alternative treatment for acne is the taking of antibiotics in pill or capsule form rather than as a cream. This option is generally chosen in more severe cases of acne where permanent scarring is a real risk, and where topical lotions and creams may not be fully effective. It’s normal for oral antibiotics to be taken in larger doses than topical applications, with a correspondingly more powerful effect.
The two such types of antibiotic in most common use for this are Lymecycline and Oxytetracycline. Both of these medications work by tackling the bacteria in the skin which can cause inflammation and trigger off acne attacks. Oral antibiotics for acne tend to have a slower effect than topical creams, but are suitable for moderate to severe acne which keeps recurring and has not been contained by other treatments.
Prescription acne treatments will usually show little immediate effect, especially when taken as oral antibiotics. Creams and gels can have a fast moisturising effect and a noticeable reduction in inflammation within a few days, but this is only a superficial result. The underlying problem usually takes several weeks or even months to be properly dealt with. It is even possible that your acne could get worse before it gets better. While this is common and not a cause for concern, if you think this is happening to you then speak to your doctor to ensure that you have no allergic reaction to the medication.
In general though, you should see some positive results within a month or two, with severe cases of acne taking up to six months to be fully cleared. An important point with all prescribed medications that contain antibiotics is to complete the full course of tablets or creams that your doctor has prescribed, even if your skin seems to have cleared up before you’ve used up all the medication.
If you stop the course early, you may still have remnants of the bacteria in your skin, causing the acne to flare up again – and in these situations the outbreak is often even worse than before.
Unfortunately, acne is a problem that can come back time after time, even after a successful treatment. This is because the underlying causes, namely hormones and skin bacteria, are naturally present throughout your life, although of course the variation in hormone levels is worse during and around teenage years. Because of this, it’s fairly common for people with severe cases of acne to continue taking a maintenance dose of medication even when there is no visible acne, so as to stop it getting a new foothold. This low dose treatment is usually continued throughout teenage years and even throughout your twenties if your acne experience has been particularly bad.
Your doctor will advise you whether or not this is necessary, but if so a common treatment is a mild antiseptic wipe containing benzoyl peroxide, or a similar topical cream, used every day or two to keep the spots at bay. It is very unusual to continue using antibiotic-based treatments for the long term, as this can lead to the bacteria in your skin becoming resistant, making future outbreaks even more difficult to deal with.
As previously mentioned, acne is generally caused by hormones and there is little that can be done to prevent an outbreak from happening. Nonetheless, taking good care of your skin can make the symptoms both less visible and less painful, and also reduce the chances of permanent scarring occurring. Things to pay attention to include:
Keep your skin as clean as possible, using gentle soaps and cleansers, without scrubbing too hard as this can irritate the skin, making the visible signs of acne more obvious as well as actually spreading bacteria around beneath the surface.
Try your best to avoid rubbing or scratching affected areas, and definitely refrain from squeezing and popping your pimples – this is a fast route to scarring.
If you shave, take care when doing so, and do it is little as possible. Use a sharp razor blade or a good quality electric shaver, and use gentle soaps, foams, or lubricants to keep skin irritation to a minimum.
Keep make-up use as low as possible, and if you do wear cosmetics, ensure that you use oil-free formulations that won’t clog up your pores too much. Also ensure that you remove your make-up properly as soon as you can, using a gentle remover.
Avoid too much sun, as both acne and some medications for it can make it easier to get sunburn, as well as drying out your skin and risking pimples turning into pockmarks.
Shampoo your hair regularly, especially if you have naturally oily or greasy hair – these oils can spread across your skin, prompting more severe acne outbreaks.
Acne is an unfortunate fact of teenage and adolescent life for most people, but for some it becomes more than an annoyance and can last far longer than normal. However, with properly supervised medical acne treatment and a good preventative skin care regime, the undoubted difficulties that acne causes can be kept in check, allowing you to get on with your life without the stress of dealing with acne.

Cystitis is a medical term for bladder inflammation. While most of the time, inflammation is caused due to bacterial infection, often it can be caused by secondary factors. It is very common in women, and very rare in men. More than 50% of women experience cystitis at least once in their lives.
Have you ever felt weak or suffered from a headache when you rode on a plane? Or maybe you felt sick to your stomach and lost your appetite when you hiked up to an elevated location. If something like this has ever happened to you, then you may have been experiencing altitude sickness. This is a general feeling of un-wellness, characterized by specific symptoms, that only affects certain people when they move to high altitudes.
While many people who are suffering from cystitis turn to their doctor for a medical treatment, many others prefer to try an alternative bladder infection treatment. Although there’s doubt that a natural bladder infection treatment will work, some of them have been effective, especially when treating mild forms of the condition. However, to best prevent the spread of cystitis, and further complications such as kidney infections, we recommend seeking confirmed medical treatments such as ... Read more
Chlamydia is a sexually transmitted disease caused by the bacteria Chlamydia Trachomatis. With an estimated 141 million cases occurring worldwide in 2013 alone, this disease is one of the most common and prevalent in the world today . While long-term effects such as blindness and arthritis are potential dangers, it is also important to understand the relationship between chlamydia and infertility.
Chlamydia is a sexually transmitted infection (STI) caused by bacteria called Chlamydia Trachomatis. The bacteria are typically transferred via semen and vaginal fluids, and it’s one of the most common STI’s in the word. Young adults and teenagers who are sexually active are at most risk. In 2013, 7 out of 10 people in England diagnosed with the bacterial infection were under the age of 25. An expectant woman with chlamydia can pass it on to their child during childbirth, so it...
