Understanding Acne: From Causes to Treatment

 


Common Causes of Acne and Their Treatment

Acne is one of the most common skin conditions affecting adolescents and adults. While often considered a cosmetic concern, acne can significantly impact self-confidence and quality of life. Understanding its causes and available treatment options can help individuals seek appropriate care and prevent long-term complications such as scarring.

What is Acne?

Dr. S. Mira Tharani

Acne occurs when hair follicles become blocked with oil (sebum), dead skin cells, and bacteria. This can lead to the development of blackheads, whiteheads, pimples, nodules, or cysts.

Acne commonly affects the:

  • Face
  • Forehead
  • Chest
  • Upper back
  • Shoulders

Common Causes of Acne

Excess Oil Production

The skin naturally produces oil to maintain hydration. Excessive oil production can clog pores and contribute to acne formation.

Hormonal Changes

Hormonal fluctuations during:

  • Adolescence
  • Menstrual cycles
  • Pregnancy
  • Polycystic Ovary Syndrome (PCOS)

can increase oil production and trigger acne.

Bacterial Growth

The bacterium Cutibacterium acnes can multiply within blocked pores, leading to inflammation and acne lesions.

Family History

Individuals with a family history of acne may be more likely to develop the condition.

Certain Medications

Some medications may contribute to acne outbreaks in susceptible individuals.

Cosmetic Products

Heavy or comedogenic cosmetic products can block pores and worsen acne.

Stress

Although stress does not directly cause acne, it may aggravate existing acne in some individuals.
