Science
Mechanism of Action
NEI-L1®'s core mechanism lies in its ability to selectively suppress Neutrophil elastase, an enzyme recognized for its detrimental role in breaking down dermal collagen. By mitigating this enzymatic activity, the peptide effectively protects the skin's essential support structures from degradation. This protective action fosters the maintenance and regulation of collagen fibers, which, in turn, translates to enhanced skin firmness, improved elasticity, and a reduction in the appearance of established wrinkles.
