what it does
A protein that binds to skin cell receptors to stimulate proliferation, differentiation, and repair. Used in post-procedure recovery products and advanced anti-aging formulations.
Sounds like sci-fi but EGF is your skin's actual repair signal protein. Gets interesting after procedures (lasers, microneedling) where healing speed matters. Large molecules have debated penetration — but post-treatment recovery data is decent.
