Acne Vulgaris Management

Assessment and Classification

The American Academy of Dermatology recommends consistently assessing acne severity using standardized scales like the Physician Global Assessment (PGA) to guide treatment selection 1, 2
Evaluation of impact on quality of life, satisfaction with appearance, and presence of scarring is crucial, as these factors may warrant more aggressive treatment 1, 2
For patients with signs of hyperandrogenism, endocrine testing is warranted, including free and total testosterone, dehydroepiandrosterone sulfate (DHEA-S), androstenedione, luteinizing hormone, and follicle-stimulating hormone 1, 3

The American Academy of Dermatology recommends a multimodal therapy combining topical retinoids with benzoyl peroxide as first-line treatment for mild acne 1, 2
For moderate acne, a fixed-dose combination of topical retinoid + benzoyl peroxide is recommended, with the addition of topical antibiotics for inflammatory lesions 1, 2, 3
For moderate-to-severe acne, oral antibiotics + topical retinoid + benzoyl peroxide are recommended, with doxycycline and minocycline as preferred oral antibiotics 1, 2
For females with hormonal acne, combined oral contraceptives or spironolactone are recommended 2, 5

Spironolactone is the first-choice oral anti-androgen therapy for hormonal acne, starting at 50-100 mg daily 5
Potassium monitoring is of low usefulness in patients without risk factors for hyperkalemia 1, 5

Using topical antibiotics as monotherapy increases the risk of bacterial resistance 2, 3
Failing to consider underlying endocrine disorders in patients with signs of hyperandrogenism 1, 3
Not using benzoyl peroxide concurrently with antibiotics to prevent resistance 2, 3

Intralesional corticosteroids may be effective for larger acne papules or nodules at risk of scarring 1
