This review examines how male facial anatomy and behavior contribute to sexual dimorphism in facial aging, pointing to factors that accelerate aging in men but presents no new clinical results.

This study found that women with acne resistant to conventional treatments had significantly higher levels of testosterone, DHEA‑S, prolactin, and LH, suggesting potential underlying hormonal disorders.

This study reported that treating wounds with a hydrogel from acellular porcine adipose tissue and adipose-derived stem cells may significantly enhance wound healing and regeneration by promoting new adipocyte formation.

This consensus concluded that oral isotretinoin is highly effective for treating acne and some off-label conditions, with common adverse events being manageable and rare serious risks not contraindicating use.

New acne treatments show promise as alternatives to traditional therapies.

This article reviews insights into the pathogenesis of primary cicatricial alopecias, such as lichen planopilaris, provided by emerging technologies, but it does not report new clinical results.

This review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

This review explores the current understanding of leptin's role in psoriasis and other skin diseases but reports no new clinical findings, emphasizing that the exact mechanisms of its impact are still being investigated.

This article discusses the clinical presentation and management challenges of menopausal acne, noting its multifactorial etiology and recommending tailored treatment approaches based on acne severity and associated features, without reporting new clinical results.

This study identified differences in adverse symptoms among patients with post-finasteride syndrome based on short and long androgen receptor gene polymorphisms.

In this study, researchers found that non-invasive analysis of skin surface lipid RNAs revealed alterations in gene expression patterns associated with atopic dermatitis, suggesting its potential for understanding skin disease pathophysiology.

This study reported higher levels of certain proteins, such as DAX-1, SRY, and WT-1, in the bald scalp of patients with androgenetic alopecia.

This study found that polymeric micelle nanocarriers delivered pharmacologically relevant amounts of spironolactone to the epidermis and upper dermis, with higher delivery to pilosebaceous units, suggesting potential for treating glucocorticoid-induced impaired wound healing and pilosebaceous androgen-related skin diseases.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

The researchers observed that normal murine hair follicles are direct targets for melatonin, with receptor expression varying throughout the hair cycle, suggesting melatonin's role in hair cycle control.

In this study, researchers observed that Malassezia species show different lipid metabolism and growth patterns depending on pH, with slightly acidic conditions promoting beneficial lipid bio-conversion for skin health, while neutral pH resulted in lower growth and lipid content, potentially negatively impacting the skin.

This commentary reviews potential dietary and mineral influences on androgenetic alopecia and suggests considering a diet low in cholesterol and glycaemic index with improved glucose control and magnesium fortification, without new clinical results.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This review highlights Stephen Rothman's influential role in transforming dermatology into a rigorous scientific discipline but does not report new clinical research outcomes.

Nutrition is important for skin health, and changing diet can help prevent and treat skin diseases.

This study found that hidradenitis suppurativa is associated with increased serum levels of hypoxia-inducible factor-1α, suggesting its role in the disease's pathogenesis and as a treatment target.

Nanoparticles can be used to deliver drugs to hair follicles, potentially improving treatments for conditions like acne and alopecia, and could also be used for vaccine delivery and gene therapy.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

This study demonstrates that Puerariae Lobatae Radix may regulate skin lipid metabolism by inhibiting sebaceous gland growth and reducing triglyceride secretion, highlighting its therapeutic potential for sebaceous gland-related conditions.

This review discusses the role of the mTORC1 pathway in acne pathogenesis in relation to diet and reports no new results.

This study found that skin surface lipids contain measurable mRNAs, providing a non-invasive way to study skin diseases, with specific gene expression changes observed in atopic dermatitis patients.

This study found that SM-215 applied to mice increased hair follicle activity and capillary presence, promoting hair growth compared to non-treatment.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

This review article examines the current understanding of frontal fibrosing alopecia, noting its prevalence in different demographics and the roles of genetic and environmental factors in its pathogenesis, while highlighting that treatment approaches remain varied and lack standardization.
