New Insights on Acne Rosacea and Hidradenitis Suppurativa

<p>This Special Issue focuses on the coping strategies of patients with hidradenitis suppurativa which is of paramount importance but at the same time often overlooked. Biologics have been introduced for the disease and may be a viable option in those with severe hidradenitis suppurativa. Skin care is extremely important in managing patients with acne and rosacea who often have sensitive skin due to skin inflammation and vigorous treatment. Optimal cosmetic products for acne and rosacea and novel treatment options such as oxybrasion and cryotherapy in managing acne are presented. Truncal acne is common but less interest has been taken in this subtype as it is not openly seen. Unlike facial acne truncal acne can develop into hypertrophic scars and needs early intervention. In addition to C. acnes fungi such as Malassezia are thought to be involved in the pathogenesis of truncal acne. An overview of truncal acne and new methods of improvement for acne scars are also discussed in this reprint. Last but not least the immunologic background in acne pathogenesis is reviewed which will help readers better understand the complex mechanism of acne development.</p>
