What is acne?
Acne is a common skin condition that causes spots.
Some people have a mild form of acne, with only occasional spots or outbreaks. Others have more severe acne, with large areas of the face and body affected.
Acne is more severe in males, but more likely to be ongoing in females. Acne most commonly affects people aged between 16 and 18 years. Acne also affects people whose skin is naturally oilier.
Acne can affect how you feel about your appearance and cause poor self-esteem.
Acne can be mild, moderate or severe. Severe acne can cause scarring.
There are different types of acne:
acne vulgaris
adult acne
Acne vulgaris
Acne vulgaris generally affects teenagers, and lasts for 3 to 5 years. Sometimes it can carry on for longer.
Adult acne
Adult acne is also called hormonal acne. This is acne that continues past the age of around 18 to 20 years. It can also start when you in adulthood.
What are the symptoms of acne?
The symptoms of acne include:
whiteheads — small white spots under the surface of the skin
blackheads — small, blocked pores with a black ‘plug’
pimples — inflamed red spots which can have yellow pus in the middle
nodules — large red bumps under the skin which can be painful
These symptoms are most often seen on the face, but acne can also affect your:
back
chest
shoulders
neck
Occasional spots or pimples are not considered to be acne.
An example of acne

What causes acne?
Acne can be caused by different factors.
Acne is caused by a build-up of dead skin cells and oil. This then forms a pimple or nodule in the skin. Bacteria can then grow in blocked pores, causing inflammation and redness.
Androgen hormones may also make your skin produce more oil. But, hormones only cause acne in a very small minority of people, such as people with polycystic ovarian syndrome (PCOS). Hormone levels also increase during puberty in teenagers and young adults.
There are other things that can trigger acne, such as:
stress
family history
diet
some medicines
being overweight
When should I see my doctor?
You should speak with your doctor if you have acne, and it is bothering you.
You should see your doctor if:
your acne is severe and causing you concern
your acne does not improve after using the treatment recommended by your pharmacist
Untreated acne can leave you with skin scars. If you think you have acne, it is important to get treatment.
Your doctor may refer you to a dermatologist (a skin specialist) if your acne is severe. They can help you decide which treatment is best for you.

How is acne diagnosed?
To diagnose acne, your doctor will check your skin for signs of acne. Sometimes, they might order a blood test to check your hormone levels.
How is acne treated?
There are many different treatments available for acne, including:
face washes or cleansers
creams
ointments
oral treatments, like tablets
Your pharmacist can recommend over-the-counter treatments for your acne.
Some treatments require a doctor’s prescription. These can help with more severe acne, or when your acne doesn’t get better with other treatments. These include:
antibiotics
anti-androgen medicines, such as the contraceptive pill
retinoids
It is important to remember that treating acne takes time. It will often take 2 to 3 months of treatment to see an improvement. Even if you don’t see your acne getting better right away, keep following the instructions for your treatment.
If your acne doesn’t improve after this time, you can ask your pharmacist or doctor about other treatments.
Washing your face
Keeping your skin clean is an important way to treat and prevent acne.
You can use a gentle, soap-free pH balanced face wash. Wash your face with warm water twice a day.
Be careful not to wash your skin too often since this may make your acne worse. If your skin still feels oily after washing, speak to your pharmacist.
Other treatments
Other treatments can help with mild acne, such as:
light microdermabrasion
chemical peels
light diathermy
These may need to be repeated regularly and are not suitable for people with severe acne.
Some natural ingredients can also help acne, such as:
alpha hydroxy acid (fruit acid)
azelaic acid
These can also irritate your skin or interfere with other medicines you might be taking. Discuss natural acne treatments with your doctor or pharmacist before using them.
How do I prevent acne?
If you have acne, there are ways to help:
prevent new spots appearing
prevent acne scars from forming
The following will help prevent spots from becoming inflamed or causing scars:
use sun protection, such as a wide brimmed hat and sunscreen
remove your makeup before you go to bed
shampoo your hair regularly, especially if it is oily and rests on your skin
have a well-balanced, healthy diet and exercise regularly
Things to avoid include:
oil-based makeup or greasy sunscreen
washing your face too often, or using harsh soaps
tight clothing over areas where you have acne
squeezing or picking spots or pimples
What complications can come with acne?
Acne can impact you both physically and mentally.
Acne scars
If left untreated, severe acne can leave life-long scars on your skin. To prevent scars, it is important to take care of your skin and treat your acne.
Treating your acne can stop it from getting infected, which can cause scarring.
Acne and self-esteem
Acne also impacts the appearance of your skin. Acne can make you feel self-conscious and affect your self-esteem. This can impact your social life and mental health.
See your doctor if you find yourself:
worrying about how you look
avoiding social situations
feeling down or upset
Your doctor can help you get the best possible treatment, advise you about body image and help you find support.
