Acne condition guide: symptoms, causes, prevention, and when to seek care. Educational only — not a diagnosis.
Overview
Acne develops when pores clog with oil, dead skin cells, and bacteria. It is common in teenagers and can continue into adulthood. It is not simply a dirt problem, though gentle face care helps.
Symptoms
- Whiteheads or blackheads
- Red pimples
- Pus-filled bumps
- Tenderness when touched
- Scars after spots heal
- Oily-looking skin
Causes
Hormone changes, excess oil, skin bacteria, and some medicines or cosmetics can contribute. Squeezing spots often worsens inflammation.
Treatment (general information)
Wash gently twice daily and avoid harsh scrubbing. Topical or oral medicines may be prescribed by a clinician. Avoid strong over-the-counter products without advice.
Prevention
Choose non-comedogenic cosmetics, keep hands off your face, and avoid constantly switching products. A balanced diet may help some people.
When to see a doctor
Seek care if acne is severe, painful, scarring, or not improving with simple care after several weeks.
Frequently asked questions
- Does food cause acne?
- Not every food, but some people notice flares with sugary drinks or lots of dairy. Track your own pattern with clinical advice.
- Does sun heal acne?
- Sun may hide redness briefly, but it damages skin and can worsen problems later.
