It is very common to develop a pimple, a red papule, a blackhead or a whitehead here or there; all of these will most probably come and go. This type is acne happens to everyone. For some people, these pimples just pass by themselves, or you can help clear your skin faster with topical products such as Acnex®, which can also prevent further breakouts.

However, sometimes these pimples can be more persistent and sometimes one spot can develop into more and can spread into many inflammatory papules and pustules. Mainly they can be found on the centre of the face but can also spread to the neck, chest and back.

If you have dark skin, the red papules may be less visible. This results in acne looking darker and slightly brown.

As individual acne lesions heal, macules form and remain on the skin until the area has healed completely. If you have light skin, the macules appear dark red or purple. If you have dark skin, these macules will look browner and perhaps almost black in colour in some cases.

To better understand the causes of acne, it is useful to learn more about the sebaceous glands, which play a vital role in the condition’s development.

Sebaceous glands

Sebaceous glands are tiny glands found near the surface of your skin. The glands are attached to hair follicles.

The triggers of acne


When teens hit puberty, hormones play an increasingly important role in the way their bodies function. Hormones are the chemical messengers that provide the signals that regulate many of your body’s functions that are responsible for the changes that are experienced during puberty.

  • Hormones: When discussing acne, one particular group of closely-related hormones called androgens are important to focus on. The main male androgen hormone is called testosterone. Boys obviously produce more testosterone than girls, and normally tend to produce more androgens which is why boys are generally bigger and have more hair on their bodies.


In cases of adult acne, most cases occur in women. It is thought that many cases of adult acne are a result of the changes in hormone levels that many women will experience at certain points during their life. Possible triggers for adult acne include:

  • Periods: some women experience a breakout of acne just before their period is due.
  • Pregnancy: many women experience symptoms of acne during pregnancy, usually during the first trimester (first three months).
  • Side-effects of medication: in some people, certain types of medication can cause acne, e.g. steroid medication and lithium (which is often used to treat depression and bipolar disorder).
