Wound healing is a complex biological process involving four overlapping stages: hemostasis, inflammation, proliferation, and maturation. Understanding these stages helps clinicians select the right dressing at the right time.
1. Hemostasis (Minutes to Hours)
The body immediately works to stop bleeding through vasoconstriction and clot formation. This is the foundation for all subsequent healing.
2. Inflammation (Days 1-4)
White blood cells clear debris and bacteria. Expect redness, warmth, and mild swelling — all normal signs the immune system is working. Antimicrobial dressings like silver alginates are often indicated here.
3. Proliferation (Days 4-21)
New tissue, collagen, and blood vessels form. Foam dressings and hydrocolloids help maintain a moist wound environment that supports granulation.
4. Maturation (21 Days to 2 Years)
Collagen remodels and the wound gains tensile strength. Thin dressings or simple protective covers are often sufficient at this stage.
Choosing dressings aligned to the healing phase — rather than a one-size-fits-all approach — significantly improves outcomes and reduces cost of care. Browse our full wound dressing catalog organized by clinical need.
