From the Guidelines
The best first-line treatment for mild acne vulgaris is topical retinoids, particularly adapalene 0.1% gel or tretinoin 0.025% cream, applied once daily at bedtime, as strongly recommended by the most recent guidelines 1.
Key Considerations
- Start with a pea-sized amount for the entire face, applying to clean, dry skin, and begin with application every other night for 2-3 weeks before advancing to nightly use to minimize irritation.
- Benzoyl peroxide 2.5-5% can be added in the morning as a complementary treatment to target bacteria, as it is also strongly recommended 1.
- Patients should use a gentle, non-comedogenic cleanser twice daily and apply a non-comedogenic moisturizer after treatment.
- Sun protection is essential as these medications can increase sun sensitivity.
Mechanism of Action
- Topical retinoids work by normalizing skin cell turnover, preventing clogged pores, and reducing inflammation.
- Benzoyl peroxide provides antimicrobial effects against P. acnes bacteria.
Treatment Outcomes
- Improvement typically takes 8-12 weeks to become noticeable, so consistency is key.
- If no improvement occurs after 12 weeks, or if side effects like excessive dryness or irritation develop, consultation with a healthcare provider is recommended for potential treatment adjustments.
Guideline Recommendations
- The guidelines strongly recommend topical retinoids, benzoyl peroxide, and topical antibiotics for the treatment of mild acne vulgaris 1.
- Conditional recommendations are made for other treatments, such as topical clascoterone, salicylic acid, and azelaic acid, but these are not considered first-line treatments 1.

From the Research
Treatment Options for Mild Acne Vulgaris
- Topical retinoids, such as adapalene, are considered a first-line treatment for mild acne vulgaris 4, 5, 6
- Adapalene has been shown to be effective in treating mild acne, with a rapid onset of action and a favorable tolerability profile compared to other retinoids 4, 5
- Combination therapy with topical retinoids and antimicrobials may be considered for moderate comedonal and mild to moderate papulopustular acne 7
Characteristics of Adapalene
- Adapalene is a retinoid agent indicated for the topical treatment of acne vulgaris 4, 5
- It has a rapid onset of action and a particularly favorable tolerability profile compared to other retinoids 4, 5
- Adapalene can be used alone in mild acne or in combination with antimicrobials in inflammatory acne 4, 5
Recommendations for Treatment
- For mild comedonal acne, monotherapy with topical retinoids is the treatment of choice 7
- Six to 8 weeks should be allowed for most treatments to work before altering the regimen 7
- Adapalene is a stable molecule that can be used in combination with benzoyl peroxide products, making it a convenient option for treating acne vulgaris 6
