Hyperpigmentation Causes

Blemishes occur for a range of reasons. There are five main types of skin blemishes:

  1. Acne (acne vulgaris)
  2. Age Spots
  3. Birthmarks
  4. Melasma
  5. Rashes

A person may have one or more of these blemishes. They can occur in size and severity differently throughout a person’s life.

The causes of each type of blemish develop for different reasons but listed below are the main causes.


The body is a delicate and complex machine. A person’s hormone levels fluctuate throughout life depending on age and gender. Examples of changes in hormones include puberty, menstruation cycles, testosterone and oestrogen level.


Depending on the type of blemish, lifestyle factors can play a big role in the appearance of blemishes on a person’s skin.

Because lifestyle factors are largely in the control of people, it is always good to assess these when looking to address blemishes.


Genetics (or how a person is made up at a DNA level) is significant in determining the occurrence of blemishes on a person’s skin. Genetics is inherited from a person’s mother and father and can’t be altered. Sometimes it is luck of the draw how frequent, significant and severe certain blemishes are.

Who Do I Have Blemishes?

A lot of people are interested in why they have blemishes compared to other people who seem to have flawless skin.

In reality, nearly everyone will experience some type of blemish in their life.


Acne is defined as a type of blemish. Acne affected almost everyone between the age brack of 14 – 18.

One in five young people will experience moderate-severe acne.

For those young people it can feel at times their acne only happens to them.

Other types of blemishes such as melasma and age spots can also make the person experiencing them feel as though they are only one of the unlucky ones. But again, the number shows a large part of the population will experience these types of blemishes too.

The prevalence rate of blemishes in the age group between 13 and 25 is 85%!

The different types of blemishes can affect people at different ages in their lives. A person may have acne when they are younger (under 30) and have fewer age spots. However, as they grow older they can have less acne but an increased number of age spots.


Myths Around Blemishes

The scientific literature around blemishes is constantly evolving.

Several studies since 2004 have demonstrated that certain types of blemishes are made no worse by a lack of hygiene. Because many blemishes are caused by intrinsic (internal) factors such as genetics, it is important for people to know those common myths and old-wives tales can cause distress when in reality the reason is at a more biological level.

There are still many factors that can cause blemishes. These factors are referred to as extrinsic (external) factors. These are the ones that people can control and therefore should focus on.

Treatments for Blemishes

Treatments for blemishes fall into two categories: Treatments and Products.

Treatments include various procedures conducted by professionals including dermatologists, plastic surgeons, and GPs, as well as beauty therapists, skincare advisors and general therapists.

For the purposes of this page, we will focus on products.


It is important that anybody thinking about purchasing products to help with their blemishes get some guidance from a professional. A lot of information on the internet can be misleading, and it is impossible to accurately read something online and ensure it fits with a person’s blemish condition.

The type of products that work best will depend on the blemish involved. For example, the type of products best for acne blemishes will be different from melasma.

A person with acne blemishes may be on a protocol that includes a BPO (benzoyl peroxide) whereas a person with melasma or age spots may have a skincare plan including skin-lightening creams such as hydroquinone.

This is why it is important for anybody with blemish concerns to be properly advised before attempting to pay for treatment or purchase products.
