Wound Healing Phase 4 - Remodeling

Welcome to Phase Four of wound healing — the remodeling (or maturation) phase — where the body transitions from repair to refinement. In this final stage, fibroblasts replace collagen type III with stronger type I collagen, reorganizing fibers to align with tension lines. The result? A scar that regains up to 80% of the original skin’s tensile strength. This phase can last weeks to months, even up to a year, depending on the patient, wound type, and systemic factors like diabetes, nutrition, and oxygenation. We'll break down the cellular players, biomechanical changes, and clinical significance of this phase for surgical wounds, pressure ulcers, and chronic wounds. Whether you're a clinician, student, or just curious about the body’s healing magic, this is the science of scar formation — demystified.
