Acne is a common skin condition that occurs when hair follicles become clogged with oil, dead skin cells, and bacteria. It most often appears on the face, chest, back, and shoulders, where sebaceous (oil) glands are more active. The blocked follicles can lead to different types of blemishes, including blackheads, whiteheads, papules, pustules, nodules, and cysts. While acne is most prevalent during adolescence due to hormonal changes, it can affect people of all ages, including adults, especially women during hormonal fluctuations such as menstruation or pregnancy.
The development of acne begins when the skin’s sebaceous glands produce excess sebum, an oily substance that helps protect and lubricate the skin. When too much sebum is produced, it combines with dead skin cells and blocks hair follicles. Bacteria naturally present on the skin can then multiply within these clogged pores, causing inflammation and the formation of spots or pimples. Depending on the severity, acne can range from mild, occasional breakouts to more persistent and painful cystic lesions.
Several factors can contribute to acne, including hormonal changes, genetics, stress, and certain cosmetic products that clog pores. Diet may also play a role, with some evidence suggesting that foods with a high glycaemic index or excessive dairy intake can worsen breakouts in some individuals. Friction or pressure on the skin from clothing, helmets, or masks can also trigger a type of acne known as acne mechanica.
Acne can have psychological effects as well as physical ones. People with visible acne may experience reduced self-esteem, embarrassment, or anxiety, particularly when breakouts are severe or persistent. This emotional impact can sometimes be greater than the physical discomfort itself, especially in teenagers and young adults who are more self-conscious about their appearance.
Good skincare habits can help manage and reduce acne. Washing the face gently twice a day, avoiding harsh scrubbing, and using non-comedogenic (non-pore-clogging) skincare products can prevent worsening of the condition. Keeping hands and hair clean, avoiding picking or squeezing spots, and protecting the skin from excessive sun exposure can also support clearer skin.
In most cases, acne improves with time, especially as hormones stabilise. However, in more persistent or severe cases, professional guidance can help identify underlying causes and create a tailored treatment plan. Early management reduces the risk of scarring and helps individuals maintain healthy skin and confidence.
