Synthetic peptides provide cost efficiency and scalability, while biotechnological approaches offer superior purity and sustainability

That single fractionation study is the proof point researchers still cite more than fifty years later as the origin of the entire copper-peptide research field: a compound identified almost by accident in a liver-aging comparison went on to become one of the most studied metallopeptides in dermal and regenerative research

The peptides in the formula are small, which means they are better absorbed into deeper layers of the skin for maximum efficacy, says Corey L
