Skin repair slows with age across several connected systems: collagen genes fire less, capillary supply thins, and repair cells lose coordination
However, some online clinics are beginning to offer prescriptions for pharmaceutical-grade peptides, which are available through compounding pharmacies that create custom medications for individual patients
With its distributed expression the H 1 R participates in ileum contraction, modulates circadian cycle, systemic vasodilatation, bronchoconstriction (allergy-induced asthma), and mediates pruritus (sensation of itchy skin)
It stimulates collagen and glycosaminoglycan synthesis in fibroblasts, foundational to skin repair and wound healing research
Both accelerate cell turnover, and using them together can overwhelm the skin
