What causes clogged pores and pimples?
NIH NIAMS explains acne forms when oil, dead skin cells and bacteria clog pores. Rising androgens in puberty, menstrual cycles and cosmetics can trigger it. Androgens are hormones that raise oil output.
Clogged pores then cause pimples, redness and swelling in teens and adults. Most teen cases are routine. Adult, hormonal and severe scarring cases still need dermatologist evaluation.
Which treatments do guidelines recommend?
The American Academy of Dermatology guidelines reported in January 2024 strongly recommend several proven options evidence summary from Dermatology Times. They list topical benzoyl peroxide, topical retinoids and antibiotics in fixed combinations, oral doxycycline, and oral isotretinoin for severe acne or scarring. A 2019 systematic review finds topical retinoids are first-line for mild-to-moderate and maintenance therapy. Retinoids are vitamin A-based creams that keep pores clear.
Adapalene shows similar efficacy but better tolerability than tretinoin or tazarotene, often combined with benzoyl peroxide. The FDA keeps all oral isotretinoin for severe recalcitrant nodular acne under iPLEDGE REMS. Nodular means large, painful lumps. The program requires prescriber, pharmacy and patient registration plus pregnancy testing and monitoring because of embryo-fetal toxicity.
Are benzoyl peroxide products safe now?
The FDA announced March 11, 2025 testing of 95 benzoyl peroxide acne products FDA benzene testing statement. More than 90% had undetectable or extremely low benzene. Six lots with elevated benzene were voluntarily recalled at retail.
That result means most tested products showed little benzene risk. A recall affects only the listed lots, not the whole ingredient. If your tube matches a recalled lot, stop use and ask a pharmacist for a replacement.
What daily routine helps treatment work?
The American Academy of Dermatology advises gentle fingertip cleansing without scrubbing or picking and popping AAD acne care page. It also recommends alcohol-free and non-comedogenic products. Non-comedogenic means made to avoid clogging pores.
You can follow three quick steps: Do not scrub, pick, or pop spots. Scrubbing and picking raise irritation and scarring risk. Tell a dermatologist about painful lumps, spreading redness, or scars that worsen.
- Wash gently with fingertips, then rinse and pat dry.
- Use lightweight non-comedogenic moisturizer daily.
- Apply sunscreen daily because retinoids and acids raise sun sensitivity.
Does diet cause acne?
A JAMA Dermatology systematic review summarized February 20, 2013 links high glycemic-index diets and frequent dairy intake to greater acne prevalence or severity. Glycemic index ranks how fast foods raise blood sugar. The studies show association, not causation, so diet may aggravate rather than cause acne.
Sugary drinks, white bread, and frequent milk are common examples readers ask about. Steady gentle care and prescribed treatment matter more for control. Track breakouts for two weeks after one steady diet change, then bring notes to a dermatologist visit.
