Use this checklist to track trial results, ask about drug type, and verify the FDA label before starting treatment. An FDA-approved acne drug is a prescription product with FDA-reviewed labeling for use, age group, and safety rules. Track efficacy, mechanism, combination ingredients, eligibility, approval pathway, and tolerability. Verify each point in the official label, not a product summary.

What did the trial measure at week 12?
Prescription acne trials often use three co-primary endpoints at week 12. Those are absolute change in inflammatory lesions, absolute change in non-inflammatory lesions, and treatment success on the Investigator's Global Assessment. IGA success usually means skin rated clear or almost clear with at least a two-grade improvement from baseline.
As reported by Practical Dermatology in its trifarotene Phase 3 report, meeting all efficacy endpoints meant hitting all three measures together (trifarotene Phase 3 results). Ask for all three results, not one lesion count alone. A drug can lower counts without producing clear or almost-clear skin.
Is it a new mechanism or a fixed combination?
Ask how the drug works and what ingredients it contains. Clascoterone 1% cream, sold as Winlevi, was approved for acne vulgaris in patients 12 years and older on August 26, 2020. According to JAMA Network Open via PMC, it was the first topical androgen-receptor inhibitor for acne (JAMA Network Open summary).
Fixed combinations need label verification for every active ingredient. Cabtreo gel contains clindamycin phosphate 1.2%, adapalene 0.15%, and benzoyl peroxide 3.1%. Bausch Health and Ortho Dermatologics announced FDA approval of Cabtreo for acne vulgaris in patients 12 and older on October 20, 2023. Check that age limit and each strength match the prescription label.
Who can use isotretinoin?
Isotretinoin is not a first option for common acne. The National Library of Medicine DailyMed label reserves it for severe recalcitrant nodular acne in non-pregnant patients 12 and older.
Eligibility has narrow clinical limits: Confirm diagnosis, prior treatment history, age, and pregnancy status before accepting it as an option. Ask what "conventional therapy" meant in your record.
- multiple nodules 5 mm or greater in diameter
- failure of conventional therapy, including systemic antibiotics
- non-pregnant status with pregnancy prevention safeguards
What must you verify before use?
Check approval pathway, pregnancy rules, tolerability, and the official label. Over-the-counter acne products using GRASE ingredients such as benzoyl peroxide can be marketed under 21 CFR Part 333 Subpart D without prior FDA new-drug approval. Other acne drugs need an approved New Drug Application.
Pregnancy safeguards are strict for isotretinoin. FDA states that isotretinoin can cause birth defects, spontaneous abortion, and premature birth and is available only through the restricted iPLEDGE REMS program (FDA iPLEDGE questions and answers). Topical drugs commonly cause early local irritation that improves after the first weeks. Confirm tolerability data, exact age indication, and directions in Drugs@FDA or DailyMed rather than relying on company summaries alone.
