Bronchogen- Summary
- Matrixyl is the most widely used collagen-stimulating cosmetic peptide. As a matrikine — a fragment of type I procollagen — it signals skin cells to synthesize new collagen, elastin, and fibronectin, reducing wrinkle depth and improving skin firmness and elasticity.
- Bronchogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Leu) developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It is a tissue-specific bioregulator designed for the bronchi and lungs, promoting normalization of bronchial epithelial cell function. Research suggests benefits for respiratory health, protection against pulmonary aging, and support for bronchopulmonary conditions.
- Half-Life
- N/A — topical; sustained signaling effects on fibroblasts persist beyond single application
- Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
