This study found that Finasteride microemulsion gel significantly reduced acne lesions in men compared to a control treatment over three months.

The study concluded that serum AMH is a useful tool for diagnosing polycystic ovarian morphology in women with persistent acne, potentially replacing transvaginal ultrasound, though it does not correlate with hyperandrogenemia.

This review highlights the potential of combining microneedling with exosome therapy in treating various dermatological conditions, but emphasizes the need for more evidence regarding its safety and effectiveness.

This study found that miRNA expression profiles in follicular fluid are altered in women with PCOS, with certain miRNAs potentially useful for distinguishing patient subtypes and contributing to understanding PCOS heterogeneity.

This genome-wide association study identified 20 genetic signals at 15 risk loci related to severe acne, revealing new insights into its genetic predisposition, particularly affecting skin structure and maintenance.

This study observed that a topical liposome formulation of a 5‐α‐reductase inhibitor effectively reduced the size of treated sebaceous glands and induced apoptosis in a hamster model, suggesting potential benefits for acne treatment.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

In this case report, the authors found that pigmented demodicosis, caused by Demodex mites, led to facial hyperpigmentation in a 16-year-old male and showed significant improvement with oral isotretinoin and topical ivermectin treatment.

This article discusses eruptive vellus hair cysts, describing their clinical characteristics, and reports no new research findings.

In this study, mice lacking the Mcpip1 gene in their myeloid cells did not develop SCC-like tumors but instead showed increased melanocyte activity and hair loss, indicating a distinct role for myeloid Mcpip1 in skin cancer development compared to keratinocyte Mcpip1.

This article outlines the clinical and histological features of milia grouped in plaques on a 59-year-old woman's face but reports no new research findings.
