Acne: Causes, Myths and Skin Care Tips That Help

Byadmin November 1, 2026

Acne happens when oil, dead skin cells and bacteria clog the pores, causing pimples, blackheads and sometimes painful bumps. It is very common, it is not caused by dirty skin, and most cases improve with a gentle, consistent routine and the right treatment.

QUICK ANSWERWash gently twice a day, use non-comedogenic products, do not pick or squeeze spots, and give any new treatment several weeks to work. See a doctor or dermatologist for deep, painful or scarring acne, or if over-the-counter products do not help.

What Causes Acne?

Acne starts in the hair follicles. The skin makes extra oil (sebum), dead skin cells block the pore, and bacteria that live on the skin multiply and cause redness and swelling. Hormonal changes during puberty, the menstrual cycle or pregnancy often play a role, and acne can also run in families.

Acne Myths vs Facts

MYTHS
  • Acne is caused by dirty skin
  • Scrubbing hard clears pimples faster
  • Squeezing spots helps them heal
FACTS
  • Over-washing and harsh scrubbing irritate skin
  • Picking can cause scars and dark marks
  • Treatments need weeks of regular use

Everyday Skin Care Tips

  • Wash your face twice a day with a mild cleanser and lukewarm water
  • Choose products labelled “non-comedogenic” or “oil-free”
  • Use a light moisturiser, because dry skin can make irritation worse
  • Apply sunscreen daily, as some acne treatments make skin more sun-sensitive
  • Wash hair and pillowcases regularly, and remove make-up before bed

Treatments That May Help

Many people start with over-the-counter products containing benzoyl peroxide, salicylic acid or adapalene. These can dry or irritate the skin, so start slowly and follow the label. For moderate to severe acne a doctor may prescribe a topical or oral treatment. Some acne medicines are not safe in pregnancy, so tell your doctor if you are pregnant or planning a pregnancy. Do not start or stop prescription medicines without medical advice.

SEE A DOCTOR IF
  • Acne is deep, painful or leaves scars
  • Over-the-counter treatment has not helped after 6 to 8 weeks
  • Acne affects your mood or confidence
  • You have sudden severe acne with other symptoms

Frequently Asked Questions

Can chocolate or oily food cause acne?

Evidence is mixed. Some people notice that high-sugar foods or dairy worsen acne, but diet is not the main cause for most people.

Should I pop my pimples?

No. Squeezing can push bacteria deeper, cause infection and increase the chance of scarring.

Does acne go away on its own?

Teenage acne often improves with age, but adult acne can persist, and treatment can help prevent scars.
