Abstract: Adapalene, a third-generation topical retinoid, has become a cornerstone in the treatment of acne vulgaris due to its proven efficacy and favorable tolerability profile. This review aims to evaluate the clinical effectiveness of adapalene, explore its mechanisms of action, and assess its role in modern acne management strategies. Adapalene primarily targets the microcomedo formation, a key factor in acne pathogenesis, through its modulation of keratinocyte differentiation and anti-inflammatory properties. Clinical studies consistently demonstrate its ability to reduce both inflammatory and non-inflammatory lesions with minimal irritation compared to older retinoids. Moreover, adapalene’s compatibility with other therapeutic agents, such as benzoyl peroxide and clindamycin, enhances its versatility in combination therapies, yielding improved patient outcomes. Emerging evidence also suggests that adapalene may play a role in addressing post-inflammatory hyperpigmentation and reducing acne-related scarring, further broadening its utility. In conclusion, adapalene remains a highly effective, well-tolerated option for the treatment of acne vulgaris across diverse patient populations. Its dual anti-inflammatory and comedolytic properties, combined with its potential for synergy with other therapies, ensure its continued relevance in dermatological practice. This review underscores the importance of individualized treatment approaches and future research to optimize adapalene’s application in acne care.
