Summary
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.
Vesilute is a tetrapeptide bioregulator (Lys-Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific for the retina and visual system. It supports retinal cell function, promotes normalization of photoreceptor protein synthesis, and is studied for age-related macular degeneration (AMD), retinal aging, and vision preservation in the elderly.
