What are 5 Causes of Acne?

Acne, the bane of many teenagers and adults alike, is a common skin condition that can affect people of all ages and backgrounds. It often appears as pimples, blackheads, whiteheads, and sometimes even painful cysts on the face, neck, chest, back, and shoulders.

While it's a widespread issue, the exact causes of acne can vary from person to person. In this blog post, we'll explore five common causes of acne to help you better understand and manage this skin condition.

Excess Sebum Production

One of the primary causes of acne is the overproduction of sebum, an oily substance produced by sebaceous glands in the skin. Sebum plays a crucial role in keeping your skin moisturized and protected. However, when your body produces too much sebum, it can mix with dead skin cells and clog hair follicles.

This can lead to the formation of pimples and other acne lesions. Hormonal changes, particularly during puberty, can trigger an increase in sebum production, making teenagers more prone to acne.

Clogged Pores

Clogged pores are a breeding ground for acne. When hair follicles become blocked by a combination of excess sebum, dead skin cells, and bacteria, it creates an environment where acne-causing bacteria (Propionibacterium acnes) can thrive. The result is the formation of blackheads and whiteheads, which can progress into more severe forms of acne if left untreated.

Bacterial Infection

Bacteria play a significant role in the development of acne. As mentioned earlier, Propionibacterium acnes, a type of bacteria that naturally resides on your skin, can multiply in clogged hair follicles. These bacteria release inflammatory substances that irritate the skin, leading to redness, swelling, and the formation of painful, pus-filled pimples.

Hormonal Fluctuations

Hormonal fluctuations can trigger or worsen acne. Changes in hormone levels, such as those that occur during puberty, menstruation, pregnancy, and menopause, can influence the production of sebum and increase the likelihood of developing acne. Androgens, a type of male hormone present in both males and females, are particularly linked to acne development. High androgen levels can lead to increased sebum production and, subsequently, more acne.

Diet and Lifestyle Factors

Your diet and lifestyle can also impact the health of your skin. While the relationship between specific foods and acne isn't entirely clear, some studies suggest that a high-glycemic diet (rich in sugary and processed foods) may exacerbate acne. Additionally, dairy products and foods with a high dairy content have been associated with an increased risk of acne in some individuals.

Stress is another lifestyle factor that can contribute to acne. High levels of stress can lead to hormonal changes in the body, which may increase sebum production and inflammation, worsening acne.


Understanding the causes of acne is essential for effective prevention and management. While genetics can also play a role in acne development, addressing factors like excess sebum production, clogged pores, bacterial infection, hormonal fluctuations, diet, and stress can significantly reduce the likelihood and severity of acne breakouts.

If you struggle with acne, consider consulting a dermatologist for personalised guidance and treatment options tailored to your specific skin type and needs. With the right care and knowledge, you can achieve clearer, healthier skin.
