This study found that an injectable material derived from hair shows good biocompatibility and promotes dermal thickness in pigs, suggesting potential as a new soft tissue filling agent.

In this study, a flexible adhesive self-powered wound dressing promoted skin regeneration and reduced inflammation in vivo using sound wave driving, without requiring skin bending or external devices.

This study's simulations revealed the complex "onion-like" organization of a lipid nanoemulsion droplet containing vitamins A and E for skin delivery, showing distinct concentration patterns of these vitamins within different layers of the nanodroplet.

This study found that N-acetyl-glucosamine-loaded nanostructured lipid carriers showed promise for skin lightening in healthy volunteers by reducing melanin distribution.

This study explored the use of dexamethasone-loaded polymer hybrid nanoparticles in a xanthan gum hydrogel for treating alopecia areata, finding that freeze drying with sucrose influenced particle size, release, and permeation, but had no impact on cytotoxicity or anti-inflammatory efficacy in human keratinocytes.

DACC-based dressings are more effective than silver-based ones for treating chronic wounds with antimicrobial resistance.

This review discusses advancements in skin microphysiological systems, such as 3D bioprinting, skin organoids, and skin-on-a-chip, and their effectiveness in emulating human skin functions for research and preclinical applications, highlighting the potential for replacing animal testing with these innovative technologies.

This case series reports promising initial data on using microneedling with a dermaroller in trichotillomania patients, indicating potential efficacy in reducing compulsive hair-pulling behaviors and promoting hair regrowth.

In this study, researchers compared the efficacy of platelet-rich plasma with microneedling versus microneedling alone for treating androgenic alopecia in 50 patients, though results are not reported in the abstract.

This review highlighted recent advances in nanocarrier-based topical delivery systems for skincare, emphasizing their potential to enhance ingredient stability, penetration, and targeted release while addressing specific pathophysiological skin concerns.

This study found that microneedling monotherapy significantly increased hair count more than topical minoxidil in androgenetic alopecia, with combination therapy of microneedling and minoxidil being even more effective. Further research is needed to evaluate microneedling's safety and efficacy as a monotherapy.

This study found that topical valproate has minimal potential to cause skin irritation, suggesting it can be applied safely to human skin.

In a study on wound healing, researchers described injectable POEGMA‐DA hydrogels as a promising non-toxic alternative to traditional wound closure methods, showing effective tissue adhesion and enhanced regeneration of skin structures in a mouse model without significant inflammation.

This study found that estradiol transdermal patches helped many MTF patients achieve target estrogen levels, especially those who could not reach these levels with oral therapy and those at higher thrombotic risk.

This study demonstrates that transfected epidermal stem cells using a novel 3D transfection system significantly enhanced wound healing and may serve as an effective therapeutic agent and gene delivery method for wound treatment.

This study demonstrated that PRP treatment improved hair metrics in androgenetic alopecia, with the dermapen method proving more effective than the point-by-point technique for specific hair growth indicators.

In this study, 51.1% of patients with androgenetic alopecia showed more than 50% improvement after undergoing five microneedling sessions at four-week intervals.

This study found that low frequency sonophoresis may reduce percutaneous absorption of sodium fluorescein-loaded liposomes by partially blocking follicular pathways in the skin.

This review discusses the potential of electrospun gelatin-based nanofiber dressings for wound healing and skin regeneration, detailing their properties, enhanced functionalities through crosslinking and bioactive components, and their application in treating challenging wound types like burns and diabetic wounds.

Combining microneedling with drugs and stem cells shows promise for improving hair growth in androgenetic alopecia.

This study developed a hydrogel from glycol chitosan and silica nanoparticles, which showed promise in wound healing by supporting microvessel and hair follicle growth in skin defects.

This guide explores the fundamental science and practical applications of nanocrystal technologies to enhance the bioavailability of poorly water-soluble drugs, detailing synthesis methods, stability solutions, and drug delivery innovations like hydrogel composites and microneedle platforms.

In this study, researchers developed a 3D chitosan/polyvinyl alcohol-tannic acid nanofiber sponge that demonstrated effective hemostatic, antibacterial, and antioxidant properties without antibiotics, accelerated wound healing in vivo, and showed high biocompatibility with L929 cells, highlighting its potential as a wound dressing for clinical use.

In this study, the authors reported that among patients with androgenetic alopecia, treatment with minoxidil 5% lotion combined with PRP and microneedling resulted in better hair growth and higher satisfaction compared to other treatment groups.

In this study, the researchers developed a cellulose nanofiber-based scaffold containing sitagliptin and zinc sulfide nanoparticles, which promoted scarless healing and hair follicle regeneration in rats by targeting DPP4+ fibroblasts, suggesting a novel approach for improved wound healing and skin regeneration.

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.
