Molecular Evaluation

The formulation was evaluated in vitro by Makrolife GmbH using human macrophage gene expression analysis. Results indicated modulation of pathways associated with inflammatory balance and angiogenesis-related signalling, supporting the biological activity profile of the peptide complex.

These findings are consistent with the formulation’s intended role in supporting skin vitality and visible resilience.
