tensile strength is achieved in 3 weeks and increases up to 2 years
myofibroblasts promote wound contraction at the proliferative phase
type III collagen is gradually replaced by type I for remodeling
epithelialization is complete in 12 hrs. by bridge formation
a scab is a temporary crust of dried blood clot that forms to protect a damaged area of the skin
some scabs are disfiguring and warrant cosmetic repair
a scar is a permanent deposition of fibrous tissue to replace damaged or lost skin
scabs will fall off on their own

hypertrophic scars usually extend beyond the borders of the original wound
keloids are the result of an overgrowth of dense fibrous tissue that usually develops after healing of a skin injury
hypertrophic scars are characterized by erythematous, pruritic, raised fibrous lesions

It is the last phase of primary wound healing
composed of dense collagen, thin-wall blood vessels
seen commonly in 2nd or 3rd- degree burns
it could lead to physical deformity and functional limitations
