This study found that 40 nm nanoparticles can effectively penetrate into hair follicles and epidermal Langerhans cells in human skin samples, potentially enabling efficient transcutaneous vaccine delivery.

This paper reviews the development of transdermal drug delivery systems for skin diseases, from first to fourth generation, and highlights ongoing challenges and the importance of clinical trials, but provides no new clinical results.

This study found that the Transdermal Delivery System efficiently delivers testosterone systemically and showed bioequivalent hormone concentrations to a known topical gel in healthy males.

This article discusses the histologic features of psoriasis, including psoriasiform epidermal hyperplasia and neutrophilic involvement, but reports no new clinical findings.

This study found that adding platelet-rich plasma to microneedling improved outcomes for atrophic acne scars more than microneedling alone, according to both quantitative and qualitative assessments.

This review explores animal models of alopecia areata, particularly focusing on the insights they've provided into the disease's immune mechanisms and potential treatment approaches, without reporting new experimental data.

This study found that while some patients with severe alopecia areata responded to high-dose prednisolone, the response was inconsistent and the therapy's risks prevent recommending it for general use.

This review discusses the multiple layers of environmental controls on hair stem cell homeostasis and suggests that targeting these layers could offer safer regenerative medicine therapies without directly using stem cells.

This study demonstrated the expression of type 1 interferon-related proteins in inflammatory lesions of alopecia areata, showing a distinct distribution pattern compared to cicatricial alopecia.

This study found that participant self-assessments suggested greater improvement in the texture and wrinkles of facial skin treated with PRP compared to normal saline, though dermatologist ratings showed no significant difference.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

This study found that intralesional triamcinolone acetonide was most effective for hair regrowth in localized alopecia areata, with betamethasone valerate foam also being beneficial, while tacrolimus ointment showed no significant effect.

This article reviews the regulation of androgens in human skin and adrenals, highlighting their role in skin disorders, but reports no new research findings.

This review discusses the development and applications of microneedles, particularly through 3D printing, highlighting their potential in transdermal drug delivery but reporting no new results.

In this study, PRP increased hair density in areas treated for androgenetic alopecia, but there was no significant difference when compared to placebo-treated areas.

The authors concluded that dermal white adipose tissue, influenced by factors like light irradiation, plays a significant role in modulating hair follicle cycles and could be targeted for hair growth treatments.

This case study highlights that breast cancer may present as alopecia refractory to usual treatments, indicating the need for consideration of underlying malignancy in such cases.

This review discusses the role of the immune niche in hair follicle regeneration and its impact on different forms of alopecia, highlighting research gaps and potential therapeutic strategies.

In this study, iNKT10 cells were found to play a significant role in preventing and treating alopecia areata in a humanized mouse model, suggesting these cells could have potential in managing related autoimmune disorders.

In this study, the combination of SCF and ET-1 was found to significantly enhance skin pigmentation and melanin content in human skin xenografts on SCID mice compared to either treatment alone.

This review discusses the aesthetic and dermatological uses of exogenous hyaluronic acid for skin rejuvenation and highlights the need for thorough investigation to confirm its claimed benefits, but it reports no new clinical findings.

This article explains that skin microneedling promotes skin regeneration by creating microinjuries, which stimulate collagen and elastin production, making it effective for treating various skin issues with high effectiveness, limited side effects, and a short recovery time.

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.

This case report describes a 78-year-old farmer with idiopathic pulmonary fibrosis who developed cutaneous Alternaria alternata infections, which improved with reduced prednisolone and itraconazole treatment, with no recurrence after two years.

This study found that α-tocopheryl acetate is well absorbed through healthy skin, with absorption occurring through specific pathways and showing high affinity for small blood vessels.
