In supplier ex-vivo testing, RG PDRN 1000 at the tested 1% concentration increased filaggrin expression by 206.55% and claudin-1 expression by 154.47% versus untreated tissue.
Filaggrin contributes to formation of the outer skin layer and natural moisturizing factors. Claudin-1 helps maintain tight junctions between epidermal cells.
