This study found that using a nonablative 1927 nm wavelength laser followed by hydroquinone cream is safe and effective for treating postinflammatory hyperpigmentation in patients with dark skin types.

This study reviewed eight studies investigating transcutaneous drug delivery via fractional laser and microneedling for alopecia treatment, with six studies showing improved hair regrowth over topical therapy alone, suggesting its potential as a promising treatment strategy, although further research is needed to refine treatment parameters.

This overview highlights an increase in nonsurgical cosmetic procedures and a growing number of male patients seeking cosmetic treatments, without reporting new clinical results.

Confocal Laser Scanning Microscopy (CLSM) is a useful tool for studying how drugs interact with skin and diagnosing skin disorders, despite some limitations.

This review discusses the psychiatric and sexual comorbidities of PCOS, emphasizing the need for a multidisciplinary approach to manage sexual dysfunction due to high prevalence rates found in recent studies.

This review highlights that while lifestyle changes may help with many ovulatory disorders, oocyte donation is considered a viable option for patients who cannot undergo ovulation induction; it reports no new results.

308 nm excimer phototherapy can help some people with alopecia areata regrow hair, especially if their condition is less severe.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

This review discusses the evolution of hair restoration surgical techniques, emphasizing that gradual improvements to existing methods are safer than radical changes, and reports no new clinical results.

This study reported significant upregulation and release of S100A4 in psoriatic skin, which may actively contribute to psoriasis pathogenesis.

This study found that melanocyte progenitor cells are present in human subcutaneous adipose tissue and may differentiate into mature melanocytes, suggesting potential applications in treating skin diseases and rejuvenation.

This study found that UVB irradiation alters skin stem cell niches leading to signs of photoaging, which may be reversed by adipose-derived stem cells through BMP4 pathway modulation and niche remodeling.

This research found that ethosomes significantly enhanced finasteride delivery into the dermis of human cadaver skin compared to liposomes in an in vitro study.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This study found a significant positive correlation between hair thickness and growth rate, with a notably slower growth rate observed in men with male pattern hair loss compared to healthy controls.

This study found that new hair follicles can form in scarred skin of injured mice, challenging the long-held belief that mammalian hair follicles cannot regenerate de novo.

Environmental factors and exposure to toxins may contribute to male infertility by affecting sperm and hormone function.

In this study, researchers developed a composite electrospun dressing with fiber gradient changes that mimics skin's natural structure, demonstrating enhanced wound healing, collagen deposition, and reduced fibrosis and scarring in both in vitro and in vivo experiments.

In this study, the authors found that applying hypobaric pressure to the skin significantly increases the transdermal permeation of large molecules by enhancing diffusion, despite the associated skin stretching and hair follicle enlargement not fully explaining this effect.

This narrative systematic review reports that gel-based, cryogel, and silicone-based cooling caps offer cost-effective and environmentally sustainable alternatives to traditional machine-operated systems for preventing chemotherapy-induced hair loss, particularly benefiting low-income and low-resource settings.
