Treatment of Acne in Children

Assessment and Classification

The American Academy of Dermatology recommends assessing acne severity using the Physician Global Assessment (PGA) or other standardized scales to determine appropriate treatment 1
Acne can affect psychological well-being even in young patients, and evaluation for potential impact on quality of life is necessary 1

The American Academy of Dermatology recommends benzoyl peroxide as the primary treatment for children under 12 with acne, starting with a low concentration of 2.5% 1, 2
Benzoyl peroxide should be applied as a thin film to affected areas once daily after washing, using a pea-sized amount for each area of the face (forehead, chin, each cheek) 3
Gentle cleansers should be used to avoid skin irritation 2

For mild acne, benzoyl peroxide monotherapy is effective, according to the American Academy of Dermatology 1, 2
For children ≥9 years with predominantly comedonal acne, adapalene 0.1% gel may be considered, with established safety and effectiveness for patients ≥9 years 1, 3
For moderate acne, combination therapy with benzoyl peroxide plus a topical antibiotic (erythromycin or clindamycin) is recommended to prevent development of antibiotic resistance 1, 2, 4
Fixed-dose combination products of benzoyl peroxide with topical antibiotics are strongly recommended by the American Academy of Dermatology 1

Tetracycline antibiotics (including doxycycline and minocycline) are contraindicated in children under 8 years due to risk of permanent tooth discoloration, according to the American Academy of Dermatology 5, 2
Most topical retinoids (except adapalene) are not FDA-approved for children under 12 years 2
Azelaic acid safety and effectiveness have not been established in children <12 years, and tazarotene safety and efficacy have not been established in patients <12 years 5

Common side effects of topical treatments include erythema, scaling, dryness, stinging/burning, and should be monitored 3, 5
Minimize exposure to sunlight and weather extremes to reduce irritation 3
Start with lower concentrations and less frequent application, then gradually increase as tolerated 2

Assess treatment response after 4-6 weeks, and monitor for potential scarring, which would indicate need for more aggressive therapy 2
If no improvement after 8-12 weeks, consider referral to a dermatologist, as recommended by the American Academy of Dermatology 1

Referral to a dermatologist is recommended for severe, nodular, or cystic acne, or if there is significant scarring or psychological distress, according to the American Academy of Dermatology 1
