What Is Acne & Why Does It Happen? (Especially in Kenya)

February 23, 2026 • 5 min read

Acne is one of the most common skin issues worldwide — and in Kenya, it feels even more frustrating because of our climate, lifestyle, and skin tones. But understanding what acne actually is can take away a lot of the confusion and shame around it.

What Exactly Is Acne?

Acne (acne vulgaris) is a chronic condition that affects the hair follicles and oil glands (sebaceous glands) in your skin. It happens when pores get blocked, oil builds up, bacteria multiply, and inflammation kicks in. It’s not caused by being “dirty” — it’s a mix of internal and external factors.

Main Causes & Triggers (Why Kenya Makes It Tougher)

• Hormones: Androgens (male hormones present in everyone) increase oil production — puberty, periods, PCOS, stress, and some contraceptives flare it up. Very common in Kenyan women in their 20s–30s.
• Humidity & Heat: Nairobi, Mombasa, and coastal areas have high humidity that makes skin oilier and clogs pores faster. Sweat + pollution = perfect storm for breakouts.
• Diet: High-glycemic foods (sugary drinks, white bread, chapati-heavy meals) and dairy (milk, ice cream) can worsen acne for many people.
• Bacteria & Clogged Pores: Dead skin cells + excess oil trap Cutibacterium acnes bacteria, leading to inflammation.
• Other Triggers: Oily hair products, heavy makeup, helmets, face masks, or steroid creams (sometimes prescribed for other issues).

Types of Acne You’ll See

• Blackheads & Whiteheads (comedones): Non-inflamed clogged pores.
• Papules & Pustules: Red, inflamed bumps and pus-filled spots.
• Nodules & Cysts: Deep, painful lumps — these can scar and need a dermatologist.

Why Dark Marks & Scars Are a Big Deal in Kenya

After acne heals, many of us get post-inflammatory hyperpigmentation (PIH) — dark brown or purple spots. On melanin-rich skin, these marks can last months or even years without treatment. Daily broad-spectrum SPF 30+ (mattifying if oily) is non-negotiable to prevent them from getting darker.

Quick Starting Tips

• Gentle cleansing twice a day (avoid harsh scrubbing)
• Use non-comedogenic (won’t block pores) moisturizer and sunscreen
• Start with one active ingredient (benzoyl peroxide, salicylic acid, or adapalene)
• Be patient — most see improvement in 8–12 weeks
