These mites are largely parasitic and consume blood, skin and keratin. Dust mites, which feed mostly on dead skin and hair shed from humans instead of consuming them from the organism directly, evolved from these parasitic ancestors.
Hypertrophic scar (4 months after incident) 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. Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.
Hypertrophic scars are another type of raised scar that can also restrict movement. Unlike keloid scars, they are within the size of the original wound. Hypertrophic scars can last for several years. Collagen gathers around the damage and builds up to help the wound seal over.The resulting scar usually fades over time, becoming smoother and less noticeable.eloid scars are shiny and hairless, they're raised above the surrounding skin, and can feel hard and rubbery.. Keloids affect around 10-15% of all wounds. They can appear anywhere on the body, but usually form on the shoulders, head and neck.
