In this study, it was observed that NIPAL4 mutations linked to autosomal recessive congenital ichthyosis lead to abnormal skin barrier function due to cytotoxic effects disrupting lipid structure and organization, which topical treatments only partially ameliorated.

This review explores how metabolic changes drive cellular quiescence and considers potential applications in cancer treatment by manipulating these processes.

This study found that alopecia in VDR-null mice persists despite undetectable vitamin D levels, indicating a defect in epithelial-mesenchymal communication due to the absence of ligand-independent receptor function.

Androgen effects on hair follicles vary by skin area.

This review examines physical methods like electron paramagnetic resonance spectroscopy, Raman spectroscopy, and differential scanning calorimetry, highlighting their complementary capabilities in analyzing biomolecular structures and mycobacterial interactions with reactive oxygen species and antioxidants.

This study reviews iron metabolism in the skin, highlighting how differentially expressed genes regulate iron recycling in the epidermis, and discusses changes in iron metabolism related to skin diseases.

This narrative review summarizes evidence on NAD⁺ biosynthesis and turnover, highlighting that while NAD⁺ precursors like NR and NMN consistently boost NAD⁺ levels in preclinical and human studies, clinical outcome results remain varied, indicating a need for more standardized human trials.

This article reviews the therapeutic use of carnitine derivatives for re-establishing mitochondrial functionality in aging and reports no new clinical results.

Staphylococcus epidermidis affects hair growth and metabolism, suggesting it could help manage hair growth issues.

This review discusses low-level light therapy for androgenetic alopecia and female pattern hair loss, noting minimal clinical evidence on its efficacy and the need for more controlled studies.

This review covers the use of photobiomodulation devices for hair regrowth in various types of alopecia and reports no new clinical results.

This review evaluates biotin's popularity and its purported benefits for hair improvement but finds no clinical evidence supporting its efficacy.

This study found that most participants were unaware that their symptoms could be related to zinc deficiency, highlighting a lack of awareness about zinc's importance in health.

This study discusses how polynucleotide-based cosmetic products can improve aging skin in patients with particular morphotypes by restoring cellular metabolism, enhancing microcirculation, and promoting intracellular matrix remodeling, offering potential benefits for reversing chrono- and photo-aging and aiding tissue recovery after cosmetic or surgical procedures.

In this study, the novel topical agent PP405 showed favorable tolerability and increased hair density by over 20% in men with advanced androgenetic alopecia after eight weeks, suggesting a promising potential treatment pending further trials.

Photobiomodulation effectively stimulates hair growth and reduces hair loss.

This article discusses the role of the hair follicle as a miniorgan involved in bioelectricity and energy transfer in living organisms, but it reports no new research findings.

This study suggests that the exercise-induced cytokine IL-15 can improve wound healing in aged skin, along with previously reported benefits on skin structure and mitochondrial function.

In this study, researchers reviewed the roles of autophagy and mitophagy in hair follicle cycles, exploring their potential links to hair loss and investigating how manipulating these pathways might offer new therapeutic strategies.

The authors report that topical skincare products containing Coenzyme Q10 can replenish CoQ10 levels, enhance skin's energy metabolism, and reduce the depth of wrinkles by providing antioxidant effects, which may help reverse signs of aging related to oxidative stress.

This study reports that retinol acetate inhibited the pro-oxidant effects of benoxaprofen on polymorphonuclear leucocytes in vitro.
