Acne is one of the most common skin conditions in the world — and one of the most misunderstood. Whether you’re dealing with the occasional breakout or persistent pimples, understanding what causes acne is the first step toward clearer skin.
The Four Main Causes of Acne
- Excess Oil (Sebum) Production
Your skin naturally produces oil to protect itself, but too much can clog pores — especially during hormonal changes like puberty, menstruation, or stress. - Clogged Hair Follicles
Dead skin cells don’t always shed properly. When they mix with oil, they can plug up your pores, creating the perfect environment for acne to form. - Bacteria (Cutibacterium acnes)
This bacteria lives on your skin naturally. When trapped in clogged pores, it can multiply and trigger inflammation — leading to red, swollen pimples. - Inflammation
Once a pore is blocked and irritated, the immune system kicks in, creating swelling, redness, and sometimes pain.
Additional Factors That Can Contribute:
- Hormones: Androgens increase oil production — that’s why acne often worsens during puberty, periods, pregnancy, or with certain medications.
- Diet: High-glycemic foods, dairy (especially skim milk), and whey protein have been linked to acne in some people.
- Stress: Doesn’t cause acne directly, but can trigger hormonal shifts that make it worse.
- Cosmetics & Skincare: Heavy, pore-clogging products (look for “non-comedogenic” labels) can contribute.
- Genetics: If your parents had acne, there’s a good chance you’re more prone to it too.
What You Can Do:
- Wash gently with a mild cleanser twice daily
- Avoid picking or popping — it increases inflammation and risk of scarring
- Choose oil-free, non-comedogenic products
- Keep an eye on diet and stress levels
- Consult a dermatologist for persistent or severe cases
Acne isn’t caused by dirt or poor hygiene — it’s a complex condition involving hormones, skin biology, and sometimes lifestyle factors. The good news? With the right approach, it can be managed — and your skin can thrive.
