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 review highlights the positive effects of platelet-rich plasma in aesthetic and regenerative medicine, particularly for skin rejuvenation, anti-aging, hair reconstruction, and wound healing, but it reports no new clinical results.

This study found that three-layer dissolving microneedles for delivering Minoxidil showed improved skin drug penetration and reduced irritation risk compared to traditional Minoxidil cream, suggesting a promising alternative for alopecia areata treatment.

This review discusses the potential applications of injectable platelet‐rich fibrin in various conditions and reports no new clinical results; the authors highlight its favorable use in comparison to existing treatments.

This randomized prospective study found that microneedling combined with autologous platelet-rich plasma resulted in significant hair regrowth and reduction in SALT score after 12 weeks in patients with chronic and stable alopecia areata, suggesting it as a safe and efficient treatment option.

This study reports that PDRN, commonly used for wound healing, may also have anti-melanogenesis and potential skin whitening effects in both experimental models and clinical settings.

In this summary of needle mesotherapy's role in treating alopecia, the researchers highlight its use in delivering beneficial substances directly to the skin or hair follicles, showing hair loss reduction after one treatment and hair regrowth after several sessions, although contraindications exist for certain populations.

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.

This study observed that while PRP therapy increased inflammation and fibrosis in photoaged skin, ADSCs therapy showed promising antiaging effects by promoting elastin and fibrillin formation and remodeling the dermis.

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 study reports that a single intradermal injection of autologous adipose-derived stem cells improved visible aging signs such as wrinkles and pore size on facial skin for over a year in eight patients, with in vitro data suggesting muscle involvement in the rejuvenation process.

In this case study, the combination of microneedling and intradermal therapy was observed to effectively stimulate hair growth and improve hair density in a menopausal woman with androgenetic alopecia, resulting in enhanced self-esteem and cosmetic satisfaction.

This study describes a novel method using force-triggered density gradient sedimentation for efficiently isolating dermal papilla cells from neonatal mouse skin, showing promise for hair follicle regeneration research.

This review discusses the potential applications of platelet rich plasma in dermatology and cosmetology for conditions like alopecia and skin rejuvenation and reports no new clinical findings.

This narrative review discusses the historical and current use of platelet-rich plasma in dermatology and reports no new clinical results; the authors suggest it may reduce the need for invasive procedures.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This study found that in dogs with post-clipping alopecia, microneedling with platelet-rich plasma may induce more rapid hair regrowth compared to microneedling alone, though results were similar by six months.

This study found that biomimetic dermal papilla spheres cultured in a specific microenvironment can partially restore hair-inducing ability in high-passage dermal papilla cells in nude mice, resembling the characteristics of primary cells.

This review discusses PRP combination therapies for androgenetic alopecia, acne scarring, and cutaneous rejuvenation, and reports increased effectiveness with combination treatments but highlights the need for more research with standardized protocols.

This study found that multiphoton microscopy effectively visualizes the microstructure of in vivo mouse skin, offering a clear view of various skin layers and components like corneocytes and collagen fibers.

This commentary discusses a study reporting that platelet-rich plasma (PRP) treatment led to increased hair growth in androgenetic alopecia patients, while critiquing its conclusion on the ineffectiveness of microneedling.

This study suggests that cold atmospheric microwave plasma treatment may promote hair renewal by activating β-catenin and YAP/TAZ signaling in human dermal papilla cells.

This study found that the cross-section trichometer (HairCheck device) can accurately and sensitively measure hair mass index changes, offering a convenient tool for assessing hair density and diameter in patients with alopecia.

This study found that implanting microencapsulated dermal papilla cells in rat ears led to hair follicle regeneration, suggesting a potential alternative to fresh isolated dermal papillae for inducing hair growth.

In this study, pantothenic acid at 20 μg/ml was observed to promote dermal papilla cell proliferation and migration, likely through up-regulation of ID3 and inhibition of Notch signaling.

This study found that combining pulsed dye laser with pingyangmycin improved treatment efficacy, scar repair, skin condition, and patient satisfaction in treating post-acne hyperplastic scars, compared to laser alone, without increasing adverse reactions.

This article discusses the potential role of telocytes in skin regeneration and the need to understand their interaction with platelet-rich plasma, reporting no new experimental results.

This study found that ring block anesthesia was the most acceptable method for reducing pain during platelet-rich plasma injections for hair loss.
