Why Growth Factors for Brows?
Biomimetic growth factors are laboratory-created proteins that replicate the body's own cell-signaling molecules. When applied topically, they communicate with follicle cells to support the natural growth cycle — helping extend the Anagen phase, reduce premature shedding, and create the conditions for visibly fuller brows over time.*
