This review concluded that the efficacy of cosmeceutical hair serums for addressing hair loss lies in their use of bioactive peptides and plant compounds, like flavonoids and sterols, that target eight key contributing factors identified in hair loss conditions.

This study found that D-peptide crosslinked MAP hydrogel accelerated material degradation in vivo but significantly enhanced skin regeneration, suggesting an adaptive immune response can drive regenerative healing even with rapid scaffold breakdown.

This study found that inhibiting TGF-β receptors in adult dermal fibroblasts restored their function and increased resistance to Staphylococcus aureus infection by enhancing their adipogenic and antimicrobial capabilities.

This study found that Pomiferin may effectively stimulate extracellular matrix protein expression in skin and scalp models, with results comparable to retinol, suggesting potential as a topical treatment ingredient.

This review reports no new results but highlights the secretory function of keratinocytes, focusing on how various secretions, notably growth factors, impact stem cell differentiation into keratinocytes.

This review highlights the potential of ellagic acid for treating various skin conditions due to its antioxidant, anti-inflammatory, and depigmenting properties, but notes that novel formulations are needed to overcome its poor solubility and skin permeability to enhance clinical efficacy.

This study suggests that the synthetic peptide SPIKENET (SPK) may protect against long-term skin alterations in mice following coronavirus infection, offering potential therapeutic intervention for similar effects in humans post-COVID-19.

This study reported that newly developed RADA16-I peptide hybrids, with active motifs like GHK and KGHK, demonstrated improved wound healing in a mouse skin injury model without cytotoxicity, suggesting they might be effective scaffolds for tissue engineering and regeneration.

This study identified key proteins, FKBP10 and FBN2, that promote the growth cycle of secondary hair follicles in cashmere goats, with higher expression in the anagen phase, offering insights into mechanisms potentially enhancing cashmere yield and quality.

This ex vivo study reported that melatonin significantly improved certain aging biomarkers in aged human skin, including reduced mTORC1 activity, increased fibrillin-1, and enhanced collagen and elastic fiber organization, though other key biomarkers remained unchanged.

The study concluded that local administration of in-vitro-expanded bone marrow-derived mesenchymal stem cells accelerates and promotes healing in full-thickness excisional wounds in adult male albino rats.

This review examines integrins as pharmacological targets, discussing current integrin-based therapies and emphasizing the need to understand integrin mechanisms for successful drug development, without reporting new clinical results.

This symposium reviewed various advances in understanding and potentially reversing skin aging, with no new experimental results reported.

This review paper highlights the development and application of organic and biogenic nanocarriers for delivering bioactives, focusing on eco-friendly and sustainable nanotechnology strategies while addressing challenges like toxicity and paving the way for future innovations in green solution approaches.

This source reviews popular cosmeceutical ingredients for skin care, noting that while they are popular among consumers for anti-aging benefits, many lack robust clinical evidence for their efficacy and safety, as they are not regulated by the FDA.

This review discusses the mechanisms involved in wound healing and explores the potential of nanomaterials as a promising approach to managing chronic wounds, but reports no new clinical findings.

In this study, patient-reported outcomes indicated that greater weight loss with GLP-1RA treatments was associated with increased reports of adverse cosmetic effects such as skin laxity, facial volume loss, and hair shedding, despite improvements in some preexisting inflammatory skin conditions.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

This review discusses the role of defensin peptides in stem cell activation for potential skin rejuvenation therapies and reports no new clinical findings, emphasizing the need for further studies.

This study evaluated the effects of topical glucocorticoids on human skin using non-invasive imaging methods and observed changes such as alterations in skin layer thickness, keratinocyte size, and collagen and elastin signal intensity.

This chapter reviews the use of liposomes and cyclodextrins to improve the delivery and effectiveness of the peptide angiotensin-(1-7) in various therapeutic applications and reports no new experimental results.

This study in diabetic db/db mice found that treatment with the antihypertensive agents minoxidil or nebivolol stimulated elastogenesis and inhibited elastolysis, leading to restored elastic fibers, reduced aortic stiffening, and normalized blood pressure.

This review examines ethosomal structures and their mechanisms as skin delivery systems, outlining preparation methods and applications but presents no new experimental findings.
