Management of Worsening Acne

Assessment and Treatment Approach

The American Academy of Dermatology recommends a combination therapy with a topical retinoid and benzoyl peroxide for a 23-year-old female with worsening acne on her cheeks, while continuing her oral contraceptive, due to the possible hormonal component or environmental trigger 1, 2
The patient's current birth control provides some benefit for hormonal acne control, but is now insufficient, suggesting the need for additional treatment 2, 3
Topical retinoid (adapalene 0.1% or tretinoin 0.025%) is recommended as the cornerstone of therapy to address comedone formation and inflammation, with a strength of evidence supporting its effectiveness 5, 2
Benzoyl peroxide (2.5-5%) is recommended to be combined with topical retinoid to reduce bacterial colonization and prevent antibiotic resistance, with a moderate strength of evidence supporting its use 1, 2
The American Academy of Dermatology suggests applying topical combination therapy once daily in the evening, starting every other day to minimize irritation, with a low strength of evidence for this specific application schedule 5, 2

For moderate inflammatory acne that doesn't respond to topical therapy, the American Academy of Dermatology recommends adding oral doxycycline 100mg daily for no more than 3-4 months, with a moderate strength of evidence supporting its effectiveness 1, 6
If primarily on cheeks with hormonal pattern, consider switching to a different combined oral contraceptive with proven efficacy for acne, such as those recommended by the American College of Obstetricians and Gynecologists, with a low strength of evidence for this specific approach 3

Emerging evidence suggests high glycemic index diets may be associated with acne exacerbations, with a low strength of evidence supporting this association 3
Limited evidence suggests some dairy products, particularly skim milk, may influence acne, with a very low strength of evidence supporting this association 3
Consider dietary modifications as an adjunctive approach if standard treatments provide insufficient improvement, with a low strength of evidence supporting the effectiveness of dietary changes 3

Using topical antibiotics as monotherapy increases the risk of bacterial resistance, with a high strength of evidence supporting this association 1, 6
Failing to combine benzoyl peroxide with antibiotics (topical or oral) may reduce treatment effectiveness, with a moderate strength of evidence supporting the importance of combination therapy 1, 2
