This review found that anti-aging peptides show promise in cosmeceuticals due to their targeted actions to rejuvenate skin, but challenges like peptide stability, penetration, and limited clinical data limit their current effectiveness.

This study found that anisotropic osmolyte solutions may improve hair follicle turnover and condition in both in vitro and in silico models, as well as in human volunteers with hair disorders.

This study found that 'smart' peptide hydrogels improved wound healing in a rat model of partial thickness burns, achieving greater wound closure and faster debridement compared to a standard treatment.

This study found that a peptide treatment using Protein disulphide isomerase improved the mechanical and thermal properties of over-bleached hair by promoting deeper peptide penetration and attachment.

This study found that IMT-P8, a novel cell-penetrating peptide, effectively facilitated the dermal delivery of proteins and peptides in mouse skin and cell lines, suggesting potential for topical applications in cosmetics and skin diseases.

This study found that 1,25 dihydroxyvitamin D3 significantly increased the expression and activity of vasculoprotective natriuretic peptide receptor-A in cultured inner medullary collecting duct cells, suggesting a potential mechanistic role in cardiovascular and renal benefits.

This study isolated a bioactive peptide from Trapa japonica fruit and found that it may protect human dermal papilla cells from DHT-induced stress, suggesting potential for biomedical applications.

This study found that topical administration of the TGFβ mimetic peptide DPS-1 stimulated hair growth in mice by promoting HDP cell proliferation and enhancing hair follicle morphology.

In this study, the researchers report that a modified epimorphin-derived peptide shows potential for hair follicle regeneration, especially when used with 1% minoxidil in mice.

This study found that the ALAVAX complex, containing 5-ALA and GHK peptide, may increase hair count in male pattern hair loss patients over 6 months without adverse events.

This study suggests that a combination of blue light photobiomodulation and biomimetic peptide infiltrations may effectively increase hair density in patients with androgenetic alopecia.

This study found that low molecular weight collagen peptide from fish may promote hair growth in both human cells and mice by activating the Wnt/β-catenin signaling pathway.

This review highlights research reporting that oral collagen peptide supplements are effective in enhancing skin elasticity, hydration, and reducing wrinkles, although results vary across studies. Oral supplementation was generally well-tolerated, and further investigation is needed to optimize formulations and explore topical application challenges.

This review outlines the various processes activated by the peptide GHK-Cu in tissue remodeling and reports improvements in skin and wound healing but notes a need for further study to fully understand these mechanisms.

This article discusses the challenges and possible solutions in hair restoration surgery, focusing on donor hair availability, hair survival, and concealing surgical evidence, and reports no new clinical results.

This study demonstrated that water-soluble peptides from egg yolk, termed "hair growth peptide," stimulated human hair follicle cell growth and improved hair growth in female pattern hair loss.

This study found that a specific fragment of AIMP1, secreted by hair follicle stem cells, activated dermal papilla cells, leading to enhanced hair regrowth and maintenance in mice.

This study found that Guasha therapy did not significantly alter nerve fiber morphology or the expression of CGRP and SP in rat skin, with parameters generally returning to normal within five days.

This study reports that the peptide GPIGS, found in Bacillus sp. M18 conditioned medium, may promote hair growth through the PI-3K/Akt pathway and accelerate hair regrowth in mice.

This study reports the crystallization of the human androgen receptor's ligand-binding domain with nonsteroidal ligands, which may aid in understanding the differences in binding compared to steroidal ligands.

This study introduced ElixirSeeker2, a computational framework for designing anti-aging peptides, and found that some newly identified peptides significantly delayed cellular senescence and enhanced cellular and locomotor functions in aged Caenorhabditis elegans.

This study found that Plant Elicitor Peptides enhance root hair growth through a mechanism independent of their known receptors, with PROPEP2 playing a key role in this process by influencing gene expression related to root hair formation.

In this study, FOL-026, a peptide based on osteopontin, was shown to promote angiogenesis and stimulate vascular cell proliferation and migration through neuropilin-1, similar to VEGF, suggesting potential therapeutic applications in vascular repair and angiogenesis-related conditions.

This study found that microspicule cosmetics with low-molecular-weight peptide complexes significantly improved skin whitening, pore condition, and skin barrier function over four weeks compared to a non-microspicule formulation.

This review discusses the challenges and potential solutions in studying Demodex mites and their possible pathogenic role in human skin disorders but reports no new findings.

This study introduced Cadd4, a peptide-based degrader developed using computer-aided drug design, which effectively reduced PCSK9 levels and increased LDL receptor expression, resulting in decreased plasma cholesterol and LDL-C levels in hypercholesterolemic mice, without liver toxicity.

In this study, peptide-based nanoparticles were successfully used to deliver the CRISPR-Cas9 system into cancer cells, effectively targeting and editing KRAS mutations, suggesting promising therapeutic potential for cancer treatment.

This review article highlights that mesotherapy, a popular non-surgical procedure in aesthetic dermatology, involves injecting a mixture of compounds into the skin for purposes like skin rejuvenation and hair loss treatment, but lacks large-scale studies on its efficacy and safety.

In this study, peptide nanofiber gels RG and RJ significantly accelerated the healing of deep second-degree burn wounds in vivo, with greater wound closure rates and enhanced tissue regeneration compared to controls, attributed to increased angiogenesis and reduced systemic inflammation.

This analytical review of alopecia treatments in the US found that drugs like minoxidil and finasteride are most affordable and effective, while newer JAK inhibitors show significant clinical results but are cost-prohibitive; the study stresses individualizing treatment based on financial capability and alopecia type.
