Science
Mechanism of Action
This peptide functions by targeting key protein structures within the dermal-epidermal junction (DEJ), including laminin, integrin, and various collagens. It actively stimulates the synthesis of critical hemidesmosomal proteins such as Laminin V, Collagens IV, VII, and XVII, along with Integrin β4. This multifaceted action enhances molecular communication and strengthens the DEJ, which is vital for skin cohesion and elasticity.
