Tripeptide-29
Summary
Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
Tripeptide-29 is a pro-collagen cosmetic peptide composed of proline, hydroxyproline, and glycine — the core repeating unit of collagen. Applied topically, it signals dermal fibroblasts that collagen degradation has occurred, triggering compensatory new collagen synthesis.
