This FAQ gives source-checked answers to common acne questions for October 2026. Acne is a hair-follicle condition in which oil, dead skin cells and bacteria clog pores and form blackheads, whiteheads, pimples or deeper nodules.
Treatment aims to heal lesions, stop new breakouts and prevent scarring. The National Institute of Arthritis and Musculoskeletal and Skin Diseases lists these goals in its acne diagnosis and treatment guide. The sections below explain options, safety findings and daily care.

What happens in acne-prone skin?
Acne starts when a hair follicle traps excess oil and dead cells. Bacteria can grow in the clogged follicle and trigger inflammation. That process produces surface blackheads and whiteheads, red pimples or painful deeper nodules.
Healing focuses on clearing active spots and blocking new clogs. Scar prevention matters because inflamed lesions and picking can damage skin. Early, steady care works better than aggressive scrubbing or spot squeezing.
Which treatments do dermatology guidelines recommend?
The American Academy of Dermatology strongly recommends benzoyl peroxide, topical retinoids, topical antibiotics and oral doxycycline in its 2024 acne guidelines, described in this report on the updated guidelines. The update replaced the 2016 guidelines. Oral isotretinoin is reserved for severe acne.
Isotretinoin treats severe recalcitrant nodular acne but carries a high risk of severe birth defects. The FDA therefore requires the iPLEDGE safety program, with prescriber, patient and pharmacy registration. It also requires pregnancy testing and contraception to prevent fetal exposure.
What is new for treatment without a prescription?
In May 2026, the FDA approved Galderma's Differin Epiduo gel for over-the-counter use in people ages 12 and older. Galderma announced the prescription-to-OTC switch in its FDA approval notice. The product combines adapalene 0.1% with benzoyl peroxide 2.5%.
Adapalene is a topical retinoid, so the switch makes a retinoid-benzoyl peroxide combination available without a prescription in the U.S. It suits families seeking a guideline-based OTC option for teens and adults. Age 12 is the lower eligibility limit.
Should you worry about benzene in benzoyl peroxide?
FDA testing reported March 11, 2025, examined 95 benzoyl-peroxide acne products. The agency found over 90% had undetectable or very low benzene, as summarized by LiVDerm in its summary of the FDA benzene findings. Six products with elevated benzene were voluntarily recalled.
Benzene can form as benzoyl peroxide degrades, especially with heat. Keep products at the labeled temperature and away from hot cars or radiators. Discard discolored, expired or heat-exposed tubes and buy fresh stock when needed.
Which habits and diet links actually matter?
Dermatologists advise gentle twice-daily cleansing with mild, oil-free or noncomedogenic products. Add daily sunscreen, avoid scrubbing, and do not pick or pop lesions. The American Medical Association, quoting board-certified dermatologists, links irritation and picking to longer-lasting pimples and higher scarring risk.
Diet plays a smaller role. Evidence reviews link high-glycemic-load diets to worse acne and report a weak possible link with milk, especially skim milk. Chocolate, salt and iodine lack demonstrated causation, according to an International Journal of Dermatology review and dermatology expert summaries. Useful daily steps are simple:.
- Wash gently morning and evening, then pat dry.
- Apply OTC medication after washing, as directed.
- Use oil-free, noncomedogenic moisturizer and sunscreen when needed.
- Keep hands off breakouts to reduce scarring risk.
