From the Guidelines
The first line treatment for acne typically involves a combination of topical retinoids and benzoyl peroxide. For mild to moderate acne, start with adapalene 0.1% gel (available over-the-counter as Differin) applied once daily at bedtime, along with benzoyl peroxide 2.5-5% wash or leave-on formulation in the morning, as recommended by the guidelines of care for the management of acne vulgaris 1. This regimen should be continued for at least 8-12 weeks to see optimal results. When applying retinoids, use a pea-sized amount for the entire face after gentle cleansing and complete drying of the skin. Expect some initial dryness, redness, or mild peeling as your skin adjusts to the retinoid—this typically improves within 2-4 weeks. A gentle, non-comedogenic moisturizer can help manage these side effects. For inflammatory acne, topical clindamycin 1% may be added to the regimen. This combination therapy works by addressing multiple factors that cause acne: retinoids normalize skin cell turnover and prevent clogged pores, benzoyl peroxide kills acne-causing bacteria and reduces inflammation, while also preventing antibiotic resistance when used with antibiotics like clindamycin.
Some key points to consider when treating acne include:
- Using multiple topical agents that affect different aspects of acne pathogenesis can be useful, as recommended by the guidelines 1.
- Combination therapy should be used in the majority of patients with acne, as it allows for a more comprehensive approach to treating the condition 1.
- Topical retinoids are the core of topical therapy for acne because they are comedolytic, resolve the precursor microcomedone lesion, and are anti-inflammatory, as noted in the guidelines 1.
- Benzoyl peroxide is effective in the prevention of bacterial resistance and is recommended for patients on topical or systemic antibiotic therapy, as stated in the guidelines 1.
It's also important to note that the guidelines recommend limiting the use of systemic antibiotics when possible to reduce the development of antibiotic resistance and other antibiotic-associated complications, and that systemic antibiotics should be used concomitantly with benzoyl peroxide and other topical therapy 1. Additionally, the guidelines suggest that intralesional corticosteroid injections can be used as an adjuvant therapy for larger acne papules or nodules, and that combined oral contraceptive pills and spironolactone can be used in certain cases of acne, as noted in the guidelines 1.
Overall, the treatment of acne should be individualized and based on the severity and type of acne, as well as the patient's medical history and other factors, as recommended by the guidelines 1.

From the Research
First-Line Treatment for Acne
The first-line treatment for acne includes:
- Topical retinoids, such as tretinoin or adapalene, which are recommended for mild to moderate acne 2, 3
- Benzoyl peroxide, which is often used in combination with topical retinoids 2, 3, 4
- Azelaic acid, which is also used as a first-line treatment for acne 3, 5
- Combination therapies, such as adapalene and benzoyl peroxide, which are effective for moderate to severe acne 6, 2, 4
Treatment Considerations
When considering treatment for acne, it's essential to:
- Assess the severity of the acne, as mild cases may be treated with topical therapies, while more severe cases may require oral antibiotics or isotretinoin 6, 3, 5
- Consider the patient's age, skin type, and medical history, as these factors can influence treatment choices 2, 4
- Educate patients on how to use topical treatments effectively and minimize potential side effects, such as irritation 4
Combination Therapies
Combination therapies, such as topical retinoids and antimicrobials, are often recommended for:
