Summary
Topical retinoids, antimicrobials, and benzoyl peroxide (BPO) are key acne vulgaris treatments. Newer formulations improve tolerability, while combining agents enhances efficacy and prevents resistance.
Area of Science:
- Dermatology
- Pharmacology
- Cosmetic Science
Background:
- Acne vulgaris treatment has evolved significantly over the past two decades.
- Topical and systemic drug options have expanded, with advancements in retinoids and galenic formulations improving efficacy and tolerability.
Purpose of the Study:
- To review the current landscape of acne vulgaris treatments.
- To highlight the efficacy and tolerability of various topical agents, including retinoids, antimicrobials, and azelaic acid.
- To discuss the role of physical removal methods and light therapies in acne management.
Main Methods:
- Review of existing literature on topical and systemic acne treatments.
- Analysis of drug mechanisms of action, clinical efficacy, and tolerability profiles.
- Evaluation of combination therapies and adjunctive treatments.
Main Results:
- Topical retinoids (e.g., tretinoin, isotretinoin, adapalene) are effective for inflammatory and non-inflammatory acne, with newer formulations offering better tolerability.
- Topical antimicrobials should be used judiciously and in combination with agents like retinoids or benzoyl peroxide (BPO) to prevent resistance.
- BPO (2-5%) remains a gold standard for papular-pustular acne, while azelaic acid is effective for comedonal acne and possesses antibacterial properties without resistance development.
- Physical removal of comedones and adjunctive light therapies show potential but require further controlled studies.
Conclusions:
- Modern acne vulgaris treatment emphasizes optimized use of topical retinoids, judicious antimicrobial use, and combination therapies.
- Advancements in formulation technology have significantly improved the tolerability of topical acne medications.
- Physical interventions and emerging light-based therapies may offer additional benefits in acne management.
