Overview of Acne

Acne is a common skin condition that affects millions of people worldwide. It occurs when hair follicles become clogged with oil (sebum) and dead skin cells, leading to the formation of pimples, blackheads or whiteheads. Acne can range from mild to severe, with forms like cystic acne and nodular acne being more painful and challenging to treat. While acne is most prevalent during adolescence due to hormonal changes it can affect people of all ages. Understanding the root causes and available treatments can significantly improve skin health and prevent complications.

Types of Acne

1. Comedonal Acne: Characterised by blackheads and whiteheads caused by clogged pores.

Often found on the forehead, nose, and chin.

2. Inflammatory Acne: Includes papules (small red bumps) and pustules (bumps with pus).

Caused by bacterial infections and inflammation.

3. Cystic Acne: A severe form of acne with deep, painful cysts filled with pus.

Commonly leads to scarring if not treated effectively.

4. Hormonal Acne: Triggered by hormonal changes, especially during puberty, menstruation, or pregnancy.

Typically appears on the lower face, jawline, and chin.

5. Fungal Acne: Caused by yeast overgrowth in hair follicles.

Leads to itchy, uniform bumps often mistaken for bacterial acne.

6. Back Acne: Affects the back and shoulders, often triggered by sweating, tight clothing, or poor hygiene.

Causes of Acne

• Overproduction of Oil (Sebum): Excessive sebum clogs pores and contributes to acne formation.
• Clogged Hair Follicles: Dead skin cells accumulate, blocking pores.
• Bacteria: The growth of acne causing bacteria like Propionibacterium acnes triggers inflammation.
• Hormonal Changes: Fluctuations during puberty, pregnancy or menstrual cycles lead to hormonal acne.
• Diet: High sugar or high fat diets may worsen acne.
• Stress: Increases cortisol levels, which can exacerbate breakouts.
• Certain Medications: Steroids and contraceptives may contribute to acne.

Complications in Acne

Permanent scarring, especially with cystic acne.

Emotional distress, anxiety or depression.

Persistent acne on areas like the back (back acne) or chest (chest acne).

Post-inflammatory hyperpigmentation or dark spots.

Risk Factors of Acne

• Age: Common during teenage years.
• Hormonal fluctuations: Seen in puberty, pregnancy, and menstrual cycles.
• Family history: A genetic predisposition to acne.
• Lifestyle habits: Poor hygiene, stress, and unhealthy diets.

Prevention of Acne

• Gentle Cleansing: Wash your face twice daily with a mild cleanser to remove excess oil and dirt.
• Non-Comedogenic Products: Use skincare and makeup products labeled non-comedogenic to prevent clogged pores.
• Avoid Touching Your Face: Prevent the spread of bacteria by keeping your hands away from your face.
