This study reports that adipose mesenchymal stem cell-derived exosomes and platelet-rich plasma both improved the condition of photoaged facial skin, with no significant difference in effectiveness between the two treatments, potentially offering a quicker and less invasive option for patients.

This study confirmed that the novel solid lipid microparticle formulation of adapalene demonstrated follicular penetration potential and targeted particle erosion in sebum in in vitro tests.

This chapter discusses the use of microneedling with PRP injection for hair growth stimulation in various types of alopecia, but it reports no new clinical outcomes.

This study developed a digital tool for quantitatively assessing hair in androgenetic alopecia, achieving an average accuracy of 79.45% for counting hairs and 68.19% for measuring hair size compared to human evaluation.

This study engineered a programmable platform using miniaturized needle arrays for drug delivery, showing improved wound healing outcomes in diabetic mice compared to standard topical treatments.

This article discusses tools for measuring hair density in donor areas to guide hair transplant surgery and reports no new clinical results; the authors emphasize the role of digital imaging in achieving consistent outcomes.

This clinical report describes a method for using tattoo marks to help align a facial prosthesis for a patient with skin flap reconstruction.

This review found that combining platelet-rich plasma with microneedling may enhance recovery and reduce toxicity in treating atrophic post-acne scars.

This study presented a case series of erosive pustular dermatosis on the scalps of elderly patients, noting unusual presentation with hypergranulation tissue and unique dermoscopic vascular patterns, diverging from typical manifestations.

In this study, researchers created a hydrogel that reduces oxidative stress and releases a pro-angiogenic drug in response to enzyme activity, which accelerated healing and improved tissue regeneration in chronic diabetic wounds during in vivo experiments.

In this study, micropigmentation was reported to be an effective method for camouflaging hair loss and scalp scars in Korean patients, with high satisfaction in 42 out of 43 cases.

This study used a novel HPLC-radiomatic flow scintillation system to measure 5α-reductase activity in dermal papillae from miniaturized hair follicles of the human occipital scalp, revealing significant variability in enzyme activity across samples.

This article discusses the development and refinement of the hair-micrografting technique in cosmetic surgery and reports no new clinical results.

Microneedling improves the appearance and feel of post-burn scars.

In this study, pneumatic injections of non-cross-linked hyaluronic acid were associated with improvements in skin texture, pores, wrinkles, and transepidermal water loss in healthy female volunteers.

This study highlights the clinical potential of microneedles as an innovative transdermal drug delivery system for treating various skin diseases with minimal pain and high patient compliance.

This study found that STAR particles, when applied to human skin, were well tolerated and highly acceptable at various pressures and with repeated daily use, suggesting they may provide a safe and effective method for enhancing drug delivery through the skin.

This study found that both intradermal injection and derma roller techniques for QR678Neo® hair regrowth therapy improved androgenetic alopecia symptoms, with intradermal injections showing non-significantly better video-microscopic outcomes but more pain and erythema associated with derma rollers.

This chapter discusses photodynamic therapy and its potential applications beyond cancer treatment, including conditions like alopecia and angina, but reports no new clinical findings.

Infliximab was effective in treating a scalp condition that did not respond to other treatments.

In this review, microneedling and platelet-rich plasma were identified as safe and effective cosmetic procedures for diverse skin types, especially among individuals with skin of color, due to their lower risk of postinflammatory hyperpigmentation and faster recovery compared to laser treatments.

This study found that dense-packing megasession follicular unit extraction is a safe and effective method for treating extensive scarring alopecia, with a graft survival rate of 85% and high patient satisfaction.

This study observed nestin-GFP expressing stem cells in the hair follicle bulge of living mice using high-resolution in-vivo multiphoton tomography, allowing migration tracking within their natural skin environment.

This study reports that using stamps to mark scalp incisions with gentian violet ink and a barrier film improved incision symmetry and maintained slot visibility for hair graft insertion in the frontal region.

This case report describes a successful treatment of sarcoidal foreign body reactions caused by permanent makeup ink with local steroid injections, while also identifying the involvement of M2 macrophages in the reaction.

This study shows that multiphoton microscopy can non-invasively distinguish scarring from non-scarring alopecia by identifying specific morphological features in hair follicle structures.

Lichen Planopilaris causes irreversible hair loss due to immune attacks on hair stem cells, but modulating PPAR-γ might help treat it.

This study demonstrated that intradermal treatment with a medical device using Polynucleotides High Purification Technology (PN HPT) significantly improved skin surface, firmness, pigmentation, and radiance in 30 Asian subjects, with benefits lasting up to six months and no adverse events reported.

In this study, AMP-303 injections demonstrated a trend toward increasing non-vellus hair count in men with mild to moderate androgenetic alopecia, notably showing a 14.5% peak increase at 60 days compared to saline, with effects lasting up to five months.
