The most influential factor is the wound bed condition—whether the bed is clean, well perfused, and capable of forming granulation tissue, with no infection. A healthy wound bed provides the environment in which healing processes can proceed: fibroblasts lay down collagen, new capillaries grow into granulation tissue, and epithelial cells can migrate to seal the wound. When infection is present or necrotic tissue dominates, inflammatory mediators and proteases damage new tissue and impede repair, slowing or halting progression toward closure regardless of wound size.

Wound size matters, but it doesn’t override the bed’s health. The color of surrounding skin isn’t a driving factor in healing rate, and while ambient temperature can affect cellular metabolism, it cannot compensate for a poorly prepared or infected wound bed.
