dermis
dur muhs
- n the deep vascular inner layer of the skin
- The idea is to heat up the underlying dermis, stimulating fibroblast cells to produce collagen, which pushes out fine wrinkles and scars.
- But if the burn is third degree and destroys the dermis down to fat and muscle, skin grafts are needed for effective healing.
- At the same time, the dermis begins to lose much of the moisture it once retained, and it becomes parched, withered and incapable of keeping the outer skin taut.
