Keloid it may ulcerate. Removing the scar is one treatment option; however, it may result in more severe consequences: the probability that the resulting surgery scar will also become a keloid is high, usually greater than 50%. Laser treatment has also been used with varying degrees of success. Keloids form within scar tissue. Collagen, used in wound repair, tends to overgrow in this area, sometimes producing a lump many times larger than that of the original scar. They can also range in color from pink to red. Although they usually occur at the site of an injury, keloids can also arise
Scar free healing significant clinical burden which is why the scar free healing concept is of interest. Some of the problems in scar healing lie in the physical outcome of the process: for example when collagen is abnormally organised in scar tissue. In scars the collagen is arranged in parallel bundles of the collagen fibres whilst healthy scar free tissue has a "basket weave" structure (Figure 1). The difference in collagen arrangement along with a lack of difference in the dermal tissue when healing has taken place with or without scarring is indicative of regenerative failure of normal skin.
