Acne Treatment Guidelines for Teens

Introduction to Acne Treatment

The American Academy of Dermatology recommends starting a topical retinoid (adapalene 0.1% or tretinoin) combined with benzoyl peroxide for acne that has not responded to over-the-counter therapy, as this represents the evidence-based standard 1, 2, 3

Topical retinoids are the cornerstone of acne therapy because they resolve the precursor microcomedone lesion that causes all acne, provide anti-inflammatory effects, and work for both comedonal and inflammatory acne 1, 2
The American Academy of Dermatology guidelines note that salicylic acid has limited clinical trial evidence demonstrating efficacy in acne, and give it only a "conditional" recommendation with "low" certainty of evidence 1, 3
Adapalene 0.1% gel is available over-the-counter, well-tolerated, and has strong evidence in adolescents 1, 3

Benzoyl peroxide provides antibacterial activity against P. acnes, prevents antibiotic resistance if antibiotics are later needed, and receives "strong" recommendations with "moderate" certainty when used in fixed-dose combination products with retinoids 1, 2, 3

If inflammatory lesions are prominent, the American Academy of Dermatology recommends adding a topical antibiotic, such as clindamycin or erythromycin, combined with benzoyl peroxide, to prevent resistance 1, 2, 3

The American Academy of Dermatology recommends considering oral antibiotics, such as doxycycline, if moderate to severe inflammatory acne persists after 8-12 weeks of topical therapy, with a limit of 3-4 months to minimize resistance 1, 3
Patients must continue topical benzoyl peroxide during and after oral antibiotic use to prevent resistance 1, 2, 3

Benzoyl peroxide remains safe in pregnancy, according to the American Academy of Dermatology 2

The American Academy of Dermatology recommends assessing response at 8-12 weeks of topical therapy, and escalating to oral antibiotics or considering hormonal therapy if inadequate improvement is seen 1, 3
