In this study, microneedling with a depth of 0.6 mm, alongside minoxidil, significantly improved hair count and thickness in patients with androgenetic alopecia compared to minoxidil alone, and was more beneficial than a 1.2 mm depth.

This study developed and tested continuous implanters for dermal papilla cell aggregates, finding that the bar-cartridge type implanter is the most effective design for continuous cell implantation in androgenetic alopecia research.

This review examined three studies on dermaroller monotherapy for hair loss, finding inconsistent efficacy and diverse methods, with risks of follicular damage and infection noted; standardized protocols are urgently needed for safe practice.

This case study describes a 34-year-old male developing painful inflammatory scalp nodules post-scalp microinfusion of medication. The findings suggest that repeated microtrauma or bacterial colonization might trigger dissecting cellulitis in susceptible individuals, with exogenous testosterone as a potential modifier, not a direct cause.

This review discusses microneedling radiofrequency in cosmetic dermatology, particularly for skin texture improvement and various conditions, and reports no new clinical results.

This article reviews the indications for micropigmentation in dermatological conditions like stable vitiligo and alopecia, but presents no new clinical results.

This literature review conducted a comprehensive analysis of existing studies on micro-needling mesotherapy in dermatology and aims to offer a practical guide for its clinical application, though it provides no new experimental findings.

This study found that micro-needling with cosmeceuticals or platelet-rich plasma significantly improved wrinkles, skin laxity, scar softening, and hair growth over 12 months, with minimal side effects, and that the best results occur with pigment and platelet massaging between 5 to 30 minutes post-treatment.

In this study, researchers measured that the MMP drug delivery technique administered approximately 1,175 μg/cm² of medication into the dermis of human skin, but these findings are specific to the experimental protocol used.

Pulsed dye laser and hydrogel dressings effectively treat hypertrophic scars.

This case study describes the successful treatment of facial pigmentation using microneedling combined with platelet-rich plasma, suggesting high effectiveness with minimal side effects in this application.

This source reviews advancements in microneedle-based cosmeceutical delivery, discussing new technologies and highlighting a burgeoning area of research involving microneedling combined with stem cell delivery for anti-aging, without finding measurable changes in skin barrier function or appearance during the study period.

The letters discussed medical tools, costs, treatment efficacy, and patient care complexities.

This review discusses the use of derma rollers for cosmetic purposes and their potential in transdermal drug delivery by summarizing evidence on their design, efficacy, safety, and concerns from preclinical and clinical reports.

Combining topical dutasteride with microneedling is more effective for hair growth than microneedling alone.

This review detailed the types and mechanisms of injectable "skin boosters" and evaluated their effectiveness and safety for mitigating age-related skin changes, providing insight into their use in contemporary dermatological practice.

The study found that a single autologous micrografting treatment using Rigenera® technology significantly improved the appearance of stretch marks in healthy women after three months, showing greater enhancements in skin properties compared to microneedling alone.

This case report observed that microneedling combined with topical minoxidil significantly increased hair growth in an elderly man with severe androgenetic alopecia compared to minoxidil alone.

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

This study found that in men with benign prostatic hyperplasia, a 3-month treatment with a long-acting GnRH agonist significantly reduced intraprostatic DHT and 3α-diol levels by about 90% and testosterone by about 75%.

This study reports that men with androgenic alopecia experience altered neuroactive steroid levels associated with persistent depression symptoms even after stopping finasteride treatment.

The researchers found that inhibiting soluble epoxide hydrolase, either genetically or pharmacologically, delayed the onset of chemically induced seizures related to GABA antagonism in experimental models.

This study found that patients with post-finasteride syndrome exhibited major depressive disorder, severe erectile dysfunction, and neuropathy, alongside altered neuroactive steroid levels in cerebrospinal fluid.

This study found that inhibiting the enzyme 5α-reductase with finasteride counteracted stress-induced prepulse inhibition deficits in socially isolated rats by altering neuroactive steroid concentrations in the brain.

This study found that drying finasteride solvates at 85 °C for one day produced a metastable anhydrous form.

This study concluded that the best approach for detecting Androsta-1,4,6-triene-3,17-dione administration in horses is monitoring the metabolites M1b or M4 in urine, detectable up to 77 hours post-administration.

In this pilot study, the Rapid Fire Hair Implanter Carousel facilitated graft placement in hair transplantation by reducing bleeding and operative time compared to the traditional manual method.

This study developed a new proteomic method to identify and assess ancient hair proteins using only small amounts of sample, providing insights into hair protein alteration processes over time.

Innovative methods are reducing animal testing and improving biomedical research.

Laser technologies improve medical treatments and outcomes.
