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.
Some scars may be depressed while others may be raised. Hypertrophic scar is one of the kinds that are raised. This scar is often confused with a keloid, which is also a raised scar. In this article, I will provide a definition for a hypertrophic scar so that you can be able to differentiate between it and a keloid.
