The October 2026 acne update brings easier access to proven treatments and clearer safety guidance. Prescription-strength combination gel is moving over the counter, benzoyl peroxide remains effective with proper storage, and isotretinoin rules and new pills are advancing. Acne is clogged pores and inflammation that cause blackheads, pimples, and cysts. A retinoid is a vitamin-A-based treatment that unclogs pores, while benzoyl peroxide kills acne bacteria and calms inflammation.

What changed at the drugstore?
Galderma received FDA approval on May 22, 2026, to sell Differin Epiduo Gel with adapalene 0.1% and benzoyl peroxide 2.5% without prescription for ages 12 and older, as reported by Galderma's approval announcement. It is the first prescription-strength retinoid plus benzoyl peroxide combination available over the counter. Shoppers should watch store rollout and pricing this fall.
Safety testing also clarified the benzoyl peroxide supply. The U.S. FDA found over 90% of 95 tested products had undetectable or very low benzene, with voluntary recalls limited to six lots, according to the FDA testing update. Affected lots included La Roche-Posay Effaclar Duo, Proactiv, Walgreens, and Zapzyt gels expiring March 2025 to March 2026.
Should you still use benzoyl peroxide?
Yes, for most users with pimples and inflamed breakouts. The ingredient retains strong efficacy support from dermatology guidelines. The issue is breakdown, not the treatment itself.
Benzene can form when benzoyl peroxide degrades in heat. Store tubes in a cool, dry place, avoid hot cars and steamy shelves, and throw away expired tubes. Do not stockpile extra gels through summer.
- Check the expiration date before each new tube
- Store cool and capped, away from heat
- Replace discolored, separated, or expired product
- Keep using daily as directed if the tube is fresh and stored well
What is changing for isotretinoin?
Isotretinoin is an oral treatment reserved for severe or resistant acne. Its iPLEDGE safety program requires pregnancy prevention because the drug can cause birth defects. FDA approved changes on Feb. 9, 2026, to permit at-home pregnancy tests during treatment and remove the 19-day lockout. Pre-treatment testing must still occur in clinic.
Rollout was delayed to Nov. 15, 2026, for system testing. Patients should confirm test rules with their prescriber before that date. Maintenance after isotretinoin remains inconsistent. A practitioner survey presented at the AAD Annual Meeting in March 2026 found highly variable care, with over three-quarters retreating severe relapse with a second course. The finding is survey opinion, not a new guideline, but it signals a need for relapse plans.
Which new pills matter?
Once-daily oral denifanstat showed progressive benefit to 52 weeks in the Phase 3 open-label extension ASC40-304 for moderate-to-severe acne. Reported results included about 57% investigator success and large lesion reductions, as summarized by Sagimet's trial announcement. The design was open-label without placebo and enrolled patients in China.
China's NMPA approved sarecycline, sold as Seysara, on Jan. 29, 2026, for inflammatory lesions of non-nodular moderate-to-severe acne in patients 9 and older. It was developed specifically for acne, unlike broad-spectrum tetracyclines. That distinction may matter for patients needing longer antibiotic courses.
What should you watch next?
Three near-term events will shape choices. The U.S. Phase 3 AURORA trial will test denifanstat in an American population.
The iPLEDGE system go-live in November 2026 should preserve uninterrupted access if clinics update workflows. Store availability and price will decide how fast OTC Epiduo Gel helps teens and adults. Ask your pharmacist when OTC Epiduo Gel arrives locally and whether it fits your current routine. Bring your benzoyl peroxide products, isotretinoin test plan, and relapse history to your next visit.
