Treatment Options for Acne Vulgaris on the Face and Shoulders

For acne vulgaris on the face and shoulders, multimodal topical therapy combining multiple mechanisms of action is strongly recommended as the most effective approach to treatment. 1

Initial Assessment and Treatment Selection

Mild Acne

• First-line treatment:
  • Topical retinoid (tretinoin, adapalene, or tazarotene) 1
  • Benzoyl peroxide (2.5-5%) 1
  • Fixed-dose combination products are preferred over monotherapy:
    • Topical retinoid + benzoyl peroxide 1
    • Topical retinoid + antibiotic (with concomitant benzoyl peroxide) 1
    • Topical antibiotic + benzoyl peroxide 1

Moderate to Severe Acne

• First-line treatment:

  • Combination of topical therapy plus:
    • Oral doxycycline (strongly recommended over other antibiotics) 1
    • Or minocycline (conditional recommendation) 1
    • Or sarecycline (conditional recommendation) 1

• For females with hormonal acne component:

  • Combined oral contraceptive pills 1
  • Spironolactone (particularly effective for adult women) 1

Specific Recommendations for Face and Shoulders

Face

1. Evening application:

   • Apply a thin layer of topical retinoid (tretinoin 0.025-0.1% or adapalene 0.1-0.3%) 1, 2
   • Wait 20-30 minutes after washing face before application 2

2. Morning application:

   • Benzoyl peroxide product (2.5-5%) 1, 3
   • Non-comedogenic moisturizer with sunscreen 2

Shoulders/Trunk

1. Benzoyl peroxide wash (more practical for larger body areas) 1
2. Consider higher strength formulations as skin on trunk is typically less sensitive than facial skin
3. For extensive involvement: Add oral antibiotic (doxycycline 100mg daily) 1

Application Techniques and Precautions

• For tretinoin:

  • Apply at night to clean, dry skin
  • Use approximately a half-inch of medication for the entire face 2
  • Avoid corners of nose, mouth, eyes, and open wounds 2
  • Expect possible initial irritation or peeling during first 2-4 weeks 2

• For benzoyl peroxide:

  • Apply thin layer to affected areas
  • Be aware it may bleach clothing and bedding
  • Can be used in combination with other topicals but apply at different times 1

Important Considerations

• Avoid topical antibiotic monotherapy to prevent bacterial resistance 1
• Always use benzoyl peroxide with antibiotics (topical or oral) to reduce antibiotic resistance 1
• Consistency is crucial - results typically take 6-12 weeks to become apparent 2
• Continue treatment even after improvement to prevent recurrence 2
• For scarring or severe psychosocial impact: Consider referral for isotretinoin evaluation 1, 4

Common Pitfalls to Avoid

1. Overuse of products - more is not better and may increase irritation 2
2. Frequent washing or harsh scrubbing - may worsen acne 2
3. Stopping treatment too soon - continue until directed by physician 2
4. Using incompatible products - avoid alcohol-based products and medicated soaps that may increase irritation 2
5. Expecting immediate results - improvement typically takes 6-12 weeks 2, 4

Recent comparative studies show that both adapalene 0.1% and benzoyl peroxide 4% have similar efficacy in treating acne in skin of color populations, with adapalene showing slightly better results for total lesion count reduction (78.1% vs 75% efficacy) 3.
