Understanding Facial Acne: Causes and Prevention

Acne vulgaris (pimples) commonly appears on the face due to multiple factors:

Primary Causes

1. Overactive sebaceous glands: Face has high density; excess sebum clogs pores.
2. Bacterial proliferation: Cutibacterium acnes (formerly P. acnes) feeds on sebum, triggering inflammation.
3. Hormonal fluctuations: Puberty, menstrual cycle, PCOS increase sebum production.
4. Follicular hyperkeratinization: Dead skin cells block pore openings.
5. Inflammation: Immune response to bacteria causes redness, swelling, pus.

Contributing Factors

• Genetics: Influences sebum production, skin sensitivity, immune response.
• Diet: High-glycemic foods, dairy may worsen acne in some.
• Stress & sleep deprivation: Increase cortisol, exacerbating inflammation.
• Medications: Corticosteroids, hormonal contraceptives, antidepressants can trigger flares.
• Cosmetics: Comedogenic products clog pores.

Management

• Gentle cleansing, non-comedogenic moisturizers.
• Topical retinoids, benzoyl peroxide, salicylic acid.
• For persistent/severe cases: see a dermatologist for prescription options (oral antibiotics, isotretinoin, hormonal therapy).

Acne can also affect chest, back, shoulders. Early treatment prevents scarring.
