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 ...
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.
In 1997, it was proven that wounds created with an instrument that are under 2mm can heal scar free, [8] but larger wounds that are larger than 2mm healed with a scar. [ 8 ] In 2013, it was proven in pig tissue that full thickness micro columns of tissue, less than 0.5mm in diameter could be removed and that the replacement tissue, was ...
The repaired region contains an abnormally large number of collagenous fibers, and relatively few blood vessels. Damaged sweat and sebaceous glands, hair follicles, muscle cells, and nerves are seldom repaired. They are usually replaced by the fibrous tissue. The result is the formation of an inflexible, fibrous scar tissue.
Granulation tissue is composed of tissue matrix supporting a variety of cell types, [3] most of which can be associated with one of the following functions: formation of extracellular matrix; operation of the immune system; vascularisation; An excess of granulation tissue (caro luxurians) is informally referred to as "proud flesh".

While this idea might sound a bit abstract, past research has shown that aging faster than normal can increase the chances of serious health issues, like a higher risk of dying or developing cancers.
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 the cut heals. This was how tattoos were initially done before the use of needles to inject ink. [17] Skin removal/skinning Skin removal allows for larger markings than simple cutting.
The average American woman will reach menopause at age 52, but onset age can range from about 45 to 58, per the Office on Women’s Health in the U.S. Department of Health and Human Services.
