Research Overview
Palifermin
Palifermin is clinically established for mucosal protection and has been studied for epithelial repair in other tissues. The strongest evidence is for epithelial resilience and regeneration rather than direct dermal remodeling.
FGF2
FGF2 has extensive preclinical and clinical literature for skin ulcers, burns, and postsurgical repair, largely through angiogenic and mesenchymal-cell signaling. It remains one of the most studied repair factors for improving tissue perfusion and remodeling.
