This study examines the role of nanotechnology in cosmetics, highlighting its benefits in improving ingredient solubility and stability, but also noting challenges such as cost, shelf life, and safety concerns, along with regulatory complexities, particularly in harmonizing global legislation.

Tattooing guidelines focus on safety, hygiene, and following rules.

This study found that alopecia areata and asthma are linked to graft dysfunction, while primary sclerosing cholangitis presents as heterogeneous, without any pleiotropy or heterogeneity in other autoimmune diseases assessed.

This study offers genetic evidence supporting a causal relationship between thyroid dysfunction and alopecia areata, which may help in managing and treating AA patients.

This study found that adapalene-loaded solid lipid microparticles may enhance targeted drug delivery into sebum due to their similarity to sebum components, although both this formulation and a standard cream showed equivalent follicular penetration.

In this study, FITC-labeled BSA nanocarriers delivered a model drug deeper into porcine ear skin hair follicles than the carriers themselves, as shown by confocal microscopy.

This study developed multifunctional nanofiber wound dressings that significantly reduced bacteria and promoted healing in a mouse wound model by incorporating antibacterial and growth-promoting agents.

In this study, a chitosan-based minoxidil nanogel was developed and optimized for better scalp retention and targeted follicular delivery, showing sustained drug release over 48 hours and improved drug deposition compared to conventional minoxidil solutions.

This study found that biodegradable PLA particles released fluorochromes in a time-dependent manner on human skin, with BP-PLA particles releasing rapidly and DiAsp-PLA particles providing sustained release and accumulation in hair follicles.

This study found that progesterone can increase glycine release in rat brainstem neurons through its conversion to allopregnanolone, which modulates presynaptic GABA receptor activity.

This study developed a chitosan-based nanogel for minoxidil, showing in vitro sustained drug release and higher deposition compared to conventional solutions, suggesting potential as an effective topical treatment for alopecia.

In this study, researchers developed a novel delivery system using hyaluronic acid gels to encapsulate Huperzine A for Alzheimer's treatment, achieving extended release over 20 days and significantly improving pathology and behavior in mice, including enhanced memory and reduced neuroinflammation.

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This study concluded that polymeric nanoparticles effectively targeted hair follicles for drug delivery, but the organogel formulation did not enhance their penetration into the hair shaft.

This study found that using drug microplates in transdermal finasteride films enhances aqueous solubility and skin permeation compared to films with pure finasteride.

This study found that artocarpin delivered via alginate/chitosan microparticles effectively suppressed the growth of hamster flank organs compared to artocarpin in solution form, without significant systemic effects.

This review discusses the various causes of hirsutism other than PCOS, emphasizing the importance of distinguishing potentially life-threatening conditions like androgen-secreting tumors from more benign causes; it reports no new clinical findings.

This study found that dutasteride-loaded nanostructured lipid carriers coated with a stearic acid-chitosan oligomer are stable, less cytotoxic, and suitable for topical delivery to promote hair growth.

This study found that dexamethasone-loaded Eudragit® L 100 nanoparticles displayed controlled drug release depending on pH levels, with minimal toxicity to human fibroblasts.

This study found that coated microneedles promoted drug release effectively, comparable to marketed minoxidil solutions, with stable performance over 30 days at high temperatures.

This study examined different polymersome systems for topical finasteride delivery and found that chitosan-decorated C7 polymersomes may enhance skin retention and provide controlled drug release compared to non-decorated systems in laboratory settings.

This study found that biodegradable hyperbranched polyesters improved the solubility and loading capacity of hydrophobic drugs, with complete pyrene release achieved in 16 days under enzymatic conditions.

This study demonstrated that treating platelet-rich plasma with ozone or procaine in vitro led to distinct changes in platelet activity, significantly enhancing the release of platelet-derived factors without damaging the platelets, indicating potential for improved regenerative therapies.

This study reviewed the pharmacological properties of fesoterodine and found that its ability to effectively treat overactive bladder, especially in the elderly, is likely due to its specific properties, including its receptor affinity, blood-brain barrier penetration, metabolic conversion, and extended-release formulation.

This study found that both a high dose of CPA and GnRHa are effective for treating hirsutism in hyperandrogenic women, but GnRHa with add-back therapy may lead to a longer remission period.

This paper reviews the diagnostic criteria, etiological factors, and treatment approaches for PCOS, highlighting the importance of considering metabolic issues such as insulin resistance and obesity, but reports no new findings.

This review discusses the classification and regulation challenges of anti-ageing cosmetics in Europe and reports no new findings; it calls for increased transparency to help consumers make informed choices.

This study found that α-13′-carboxychromanol significantly accelerated wound healing and improved tissue quality in a mouse model, especially when delivered with bacterial nanocellulose under diabetic conditions.

This study found that mutations in the TULP3 gene are associated with progressive degeneration of the liver, kidney, and heart in adults, highlighting the importance of early detection and management.

This study found that older patients with Cushing's syndrome had fewer typical symptoms of hypercortisolism, more comorbidities, and were more often treated conservatively compared to younger patients.
