In the event of an injury that damages the skin's protective barrier, the body triggers a response called wound healing. After hemostasis, inflammation white blood cells, including phagocytic macrophages arrive at the injury site. Once the invading microorganisms have been brought under control, the skin proceeds to heal itself.
Heat has the opposite effect of ice, which restricts blood flow and slows the healing process. The use of heat will open up the blood vessels in the affected area. This helps speed up the healing process as well as reduce the possibility of persistent stagnation in the affected area and reduce the risk of future re-injury. [15]
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue. Some tissues such as skin, the vas deferens , and large organs including the liver can regrow quite readily, while others have been thought to have little or no capacity for regeneration following an injury.
The scars tend to spread as they heal, so final designs are usually simple, the details being lost during healing. Scarification being created. Some common scarification techniques include: Ink rubbing Tattoo ink (or similar agent) is rubbed into a fresh cut to add color or extra visibility to the scar. Most of the ink remains in the skin as ...
Scar free healing is the process by which significant injuries can heal without permanent damage to the tissue the injury has affected. In most healing, scars form due to the fibrosis and wound contraction, however in scar free healing, tissue is completely regenerated. During the 1990s, published research on the subject increased; it is a ...
A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.
Scar revision is a process of cutting the scar tissue out. After the excision, the new wound is usually closed up to heal by primary intention , instead of secondary intention . Deeper cuts need a multilayered closure to heal optimally, otherwise depressed or dented scars can result.
