How long can the proliferation phase of wound healing last?

The proliferation phase of wound healing can last up to 42 days, making it a critical period for tissue repair and regeneration. During this phase, various cellular processes occur, including the migration and proliferation of fibroblasts, which are essential for collagen synthesis. Angiogenesis, or the formation of new blood vessels, also takes place, ensuring the wound gets adequate oxygen and nutrients to support healing.

The duration of the proliferation phase can be influenced by several factors, such as the type and severity of the wound, the individual's overall health, and any underlying medical conditions. Understanding this timeframe is vital for estheticians and healthcare providers, as it helps guide expectations for recovery and informs the appropriate timing for interventions, such as advanced skincare treatments, to promote optimal healing.
