Acne

Acne is a very common condition that affects most adolescents, as well as some adults; and can also occur in adults – even those who’ve previously never had issues.

Overview

While every individual is different, and genetics may play a role in acne, it is most commonly associated with periods of hormonal change, which is why the condition may be prevalent during puberty; and why some women may observe the onset or exacerbation of acne during pregnancy, or as part of menstruation.

As the condition is so common, there is a significant amount of misleading information shared about what causes acne, as well as how to ‘cure’ it. There is no evidence that diet, poor hygiene or sexual activity play a role in the condition; and cosmetic products or treatments can often aggravate the skin - causing acne to worsen, or creating secondary issues that require specialist dermatology treatment.

While acne can vary in severity (from a few spots appearing once in a while; to prolonged, significant issues that leave deep scarring) and the condition can present in different areas of the body, generally, all forms of acne can have a detrimental impact on self-confidence. In most teens, acne resolves itself once the effects of puberty hormones taper off (usually around the age of 20), but for some people, the condition can persist into adulthood, or recur later on.



Acne cases represent around 20% of Derma patients, although most people with mild acne respond well to readily available over-the-counter treatments, and do not require specialist dermatological attention.



Symptoms of Acne

Acne can appear anywhere on the body – except the palms of the hands and soles of the feet, which do not have sebaceous glands - but the condition most commonly presents on the face, back, chest, shoulders or arms. 

There are 6 main manifestations of acne, each of which can cause distress – but some may present more serious issues than others if left untreated, or if treated improperly.

These small black, dark brown, or yellowish bumps develop on the skin. Contrary to popular belief, their colour does not indicate they’re ‘filled with dirt.’ Instead, blackheads are tinted due to the colour produced by the inner lining of the hair follicle.

While these will have a similar appearance to blackheads, whiteheads lack the discolouration, may be firmer to the touch, and do not respond to traditional extraction methods, such as ‘squeezing.’

These small red bumps may feel tender or sore, and many people consider them to mean they have a spot ‘coming up.’ Extraction methods such as ‘squeezing’ may result in further inflammation, soreness, and even cause more serious issues like infection or permanent scarring.

While these may begin as papules, this type of spot is noted to feature a white tip in the centre, caused by a build-up of pus (a liquid produced in infected tissue, consisting of dead white blood cells and bacteria with tissue debris and serum.) Extracting, or ‘squeezing’ pustules may be tempting, but can worsen the problem, leading to infection or permanent scars.

These large hard lumps build up beneath the surface of the skin and can be very painful. They are more serious than the more common papules, and affect deeper layers of the skin. Extraction methods such as ‘squeezing’ should be avoided lest they cause more damage, infection or permanent scarring to the skin.

Also called ‘cystic acne,’ these are the most severe form of acne, where the pores of the skin become blocked, resulting in inflammation and infection. Cysts present as large pus-filled lumps, and they carry the greatest risk of permanent scars. Never try to extract a cyst yourself, as to do so can create serious complications and damage.

Causes of Acne

Blackheads, whiteheads, papules and pustules are the most commonly seen in cases of mild- to moderate acne, while the more serious presentations of nodules and cysts are rarer.

Acne is caused when the sebaceous glands in the skin produce excess oil, while at the same time, the follicles on the skin are blocked by a build-up of dead skin cells. This overproduction of oil results in the build-up that causes blackheads and whiteheads, as well as the more painful papules and pustules.

In nodules, this process occurs deeper in the layers of the skin, and in the instances of cystic acne, the pores of the skin become so blocked that they result in infection and inflammation.

While all acne can leave scarring – particularly if efforts to extract, or ‘squeeze’ spots worsen the condition – the risk is highest with cystic acne, which is likely to require medical attention.

Perfume, cologne, and even additives in washing powder contain synthetic fragrance, which is known to irritate the skin, and may contain chemicals that contribute to clogged pores or hair follicles.
As with fragrances, chemicals in cosmetic products for the face, body and hair can irritate skin and clog pores. Additionally, many products contain sulfates and synthetic colours which are not suitable for everyone.
Any material that rubs, or traps sweat and other bacteria against the skin can increase the risk of developing acne, or worsening an existing condition. Additionally, repeated friction on the skin can cause acne mechanica, a condition common in athletes, students, and soldiers.
Even if they look clean, bath towels and sheets collect dead skin cells, dust mites, and bacteria, which can then transfer to the skin. Additionally, they may be washed with products that contain acne-aggravating fragrances.
Whilst there is little evidence that your diet causes acne, Excessive dairy, refined food, sugars and meat proteins may be linked

Treatment of Acne at Derma

The majority of adolescents and adults suffer from mild acne, but luckily the condition can often be managed using topical over-the-counter acne treatments that can be obtained from a pharmacist.

These over-the-counter products incorporate a variety of anti-acne agents, such as benzoyl peroxide, which is suitable for most people, and is often used once a day or less frequently, if it causes dryness.

More severe cases require treatment with antibiotics or, if they fail to eradicate the acne, with isotretinoin.

Isotretinoin is commonly known by its trade name, Roaccutane. The side effects of isotretinoin treatment can be serious, so only dermatologists are allowed to prescribe it, and close monitoring of the patient is required during the treatment.

Fungal acne, also known as Malassezia folliculitis, is a condition that looks very similar to acne.  It produces papules and pustules that often appear on the face, upper back, chest, shoulders and arms. The difference to normal acne is that they are intensely itchy and is commonly found in hot, humid climates, particularly those affected by excessive sweating. It is treated with oral antifungal medication. Topical antifungals can be used for prophylaxis as recurrence is common.
