What Is Acne?

A Medical Overview of a Common Skin Condition

Acne is a common skin condition that affects the hair follicles and oil-producing (sebaceous) glands of the skin. It most often appears on the face, chest, shoulders, and back areas where sebaceous glands are more active.

Although acne is commonly associated with adolescence, it can affect people of all ages, including adults.

How Acne Develops in the Skin

Healthy skin continuously sheds dead skin cells. In acne-prone skin, these dead cells may accumulate and block the opening of a hair follicle. At the same time, the sebaceous glands may produce increased amounts of sebum (skin oil).

When a follicle becomes blocked with sebum and dead skin cells, bacteria, particularly Cutibacterium acnes, can multiply within the follicle. This process may trigger inflammation, which leads to the visible skin changes associated with acne.

Common Signs and Symptoms of Acne

Acne can present in different forms, depending on severity and individual skin response. Common acne lesions include:

  • Blackheads (open comedones): Blocked pores that remain open at the skin surface.
  • Whiteheads (closed comedones): Blocked pores covered by a thin layer of skin.
  • Papules: Small, red, inflamed bumps.
  • Pustules: Inflamed lesions containing visible pus.
  • Nodules and cysts: Larger, deeper, and often painful lesions that may increase the risk of scarring.

The appearance and severity of acne can vary widely between individuals.

Who Is Commonly Affected by Acne?

Acne is most common during puberty, when hormonal changes stimulate increased sebum production. However, it may also affect:

  • Adults, particularly women.
  • People with a family history of acne.
  • Individuals using certain medications that affect hormones or skin cell turnover.

Adult acne may persist from adolescence or develop later in life.

Factors That May Influence Acne Severity

Several factors are known to influence the development or severity of acne, including:

  • Hormonal changes, such as those occurring during puberty, pregnancy, or menstrual cycles.
  • Genetic predisposition
  • Certain medications, including corticosteroids and some hormone related treatments.
  • Friction or pressure on the skin, for example from tight clothing or equipment.
  • Skincare or cosmetic products that may block pores.

Diet and stress are often discussed in relation to acne, but their role varies between individuals and continues to be studied.

When to Seek Medical Advice for Acne

Medical advice may be helpful if acne:

  • Is severe, painful, or worsening
  • Causes scarring or long-lasting dark marks
  • Does not improve over time
  • Has a significant emotional or psychological impact

A healthcare professional can assess the condition and provide appropriate guidance.

Key Points to Remember About Acne

  • Acne is a medical skin condition involving blocked hair follicles, excess oil, bacteria, and inflammation.
  • It affects both adolescents and adults.
  • Acne presents in different forms and levels of severity.
  • Persistent or severe acne may benefit from medical assessment.
