Ovagen- Summary
- Nonapeptide-1 is a synthetic 9-amino acid peptide that inhibits melanin production by blocking α-MSH (alpha-melanocyte stimulating hormone) receptor binding. Used in cosmetic formulations for skin lightening and evening skin tone, it is particularly effective for UV-induced and hormonal hyperpigmentation.
- Ovagen is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, primarily targeting liver tissue. It supports hepatocyte function, liver cell regeneration, and protection against hepatic aging and disease. Ovagen is used in protocols for chronic liver disease, hepatoprotection, and metabolic liver conditions including fatty liver disease.
