Acne. An overview of clinical research findings

Although acne represents the most common chronic skin condition seen by dermatologists, there are still many unanswered questions regarding its pathophysiology, and patients are still in need of more effective therapies, particularly those aimed at the hormonal aspects of acne. Recent clinical research has led to advances in our understanding of factors such as cytokines in follicular hyperkeratinization and the role of androgens in acne, the emergence and significance of antibiotic resistance of P. acnes, the long-term safety and efficacy of isotretinoin, and the safety and efficacy of new topical retinoids, such as tazarotene and adapalene. Fruitful interactions between basic scientists and clinical researchers within medicine and the pharmaceutical industry will, it is hoped, provide for future advances in this area.
