Root Causes: Unravelling the Mystery Behind Acne

Acne, a skin condition that affects up to 85% of people between the ages of 12 and 24, is something many of us have experienced. However, understanding the root causes of acne can sometimes feel like unravelling a complex mystery. With several influencing factors coming into play, from hormones to diet, and even genetics, pinpointing the exact cause can be tricky. This blog post aims to demystify acne, by taking a closer look at its causes, and ultimately helping you take a proactive approach in managing it.

What Triggers Acne?

Let's start with the basics. Acne occurs when your hair follicles become clogged with oil and dead skin cells. This clogging can result in various types of spots, including blackheads, whiteheads, and the more severe forms, such as nodules and cystic lesions. But what triggers this clogging in the first place?


A significant player in the onset of acne is our hormones, specifically androgens. Androgens are a type of hormone that increases in both boys and girls during puberty, causing the sebaceous glands to enlarge and produce more sebum. This overproduction of oil can block the pores, leading to acne. Hormonal changes during menstruation or pregnancy can also result in adult acne.

Genetic Factors

Studies have shown that genetics can also play a role in acne. If your parents had acne, it increases your likelihood of dealing with it too. Though scientists have yet to identify a specific "acne gene," several genetic factors could influence your skin's sensitivity to hormonal changes and your immune system's response to inflammation, both of which can contribute to acne.


While research is still ongoing, certain foods have been linked to acne. Diets high in refined sugars and carbohydrates can increase inflammation and promote sebum production, leading to acne. Foods with a high glycaemic index, such as white bread, pasta, and sweets, can trigger this effect. Additionally, dairy products might worsen acne in some individuals.


Ever noticed how your acne seems to flare up during stressful periods? While stress doesn't directly cause acne, it can worsen the condition. Stress increases the production of hormones that stimulate oil production, leading to more clogged pores and acne breakouts.

Certain Medications

Some medications, including certain types of birth control pills and corticosteroids, can also lead to acne.

Environmental Factors

External factors can also contribute to the onset of acne:

Pressure or Friction on the Skin

Acne can also appear in areas where there is constant pressure or friction, such as where your helmet or backpack strap might rest. This type of acne, known as acne mechanica, is common in athletes and those who sweat a lot.

Pollution and Humidity

Living in a polluted area or one with high humidity can exacerbate acne, as these conditions can cause sweat and oil to stay on the skin, leading to clogged pores.

Skincare Products

Finally, the products you put on your skin matter. Some cosmetics, lotions, and sunscreens can clog pores, leading to acne. Look for products labeled as non-comedogenic, which means they are designed not to clog pores.

Understanding the Causes to Manage Acne Effectively

While the root causes of acne can be multi-faceted, understanding these contributing factors can help manage and potentially prevent breakouts. It's essential to maintain a regular skincare routine, focusing on gentle cleansing, and using products suitable for your skin type. If you struggle with persistent or severe acne, consult with a dermatologist or healthcare professional. They can help you find a treatment plan tailored to your skin's needs, taking into account the various causes discussed here.

Acne is a common condition that many individuals deal with at some point in their lives. Though it can be frustrating and even embarrassing, remember that it is not your fault. It does not reflect your hygiene or lifestyle. It is a complex skin condition with a variety of causes, many of which are out of your control. What's within your control is how you manage it. Knowledge is the first step to taking charge, and by understanding the causes of acne, you are on your way to better skin health.
