Latent period: During the haemostatic and inflammatory phase of the wound healing process, vasodilation and permeabilisation allow leukocyte extravasation and phagocytic debridement and decontamination of the wound area. Tissue swelling aids later angiogenesis by expanding and loosening the existing collagenous extracellular matrix.
A week after the injury, the edges of the wound are pulled together by contraction. Contraction is an important part of the healing process when damage has been extensive, and involves shrinking in size of underlying contractile connective tissue, which brings the wound margins toward one another.

This stage is followed by the inflammatory phase which typically lasts 1 to 3 days. Proliferation is the third stage of wound healing and lasts from a few days up to a month. The fourth and final phase of wound healing, remodeling/scar formation, typically lasts 12 months but can continue as long as 2 years after the initial injury.
Dermal macrophages are arrested at the pro-inflammatory phenotype, which increases the difficulty in the healing process due to their production of pro-inflammatory cytokines. [4] Ulcers on foot are common in a patient with severe diabetes due to the prolonged impairment of wound healing.
In diabetic wounds, the inflammatory phase of the healing process is prolonged, delaying the formation of mature granulation tissue and reducing the healing wound's tensile strength. [ 3 ] Treatment of diabetic foot ulcers includes blood sugar control, removal of dead tissue from the wound , wound dressings , and removing pressure from the ...
Yeatman reflects on a quote from the German physician, Rudolf Virchow, from over a century ago who proposed that cancer is like a chronically inflamed, poorly healing wound. “The inflammation ...
For instance, in wound healing, P21 has been found to allow mammals to heal spontaneously. It even allows some mammals (like mice) to heal wounds without scars. [5] [6] The LIN28 gene also plays a role in wound healing. It is dormant in most mammals. [7] Also, the proteins MG53 and TGF beta 1 play important roles in wound healing. [8]
Antioxidants: Antioxidants, including vitamin C and sea buckthorn extract, can protect the skin from environmental aggressors, minimize inflammation and stimulate wound healing, says Ibrahim.
