40
When the barrier of the skin is breached, the body responds to the injury in these three phases
1. Inflammatory phase (fight infection)
2. Proliferative phase (cover the injured area)
3. Maturation phase (permanently patch the damage)
41
Describe the inflammatory phase
Begins immediately after injury. Area becomes inflamed. Clear lymph flows, carrying infection-fighting lymphocytes. Blood vessels constrict to limit blood loss. Vessels then dilate to flood the area with plasma. Monocytes arrive to remove foreign objects, engulfing pigment molecules. Fibrinogen converts to sticky fibrin to form clots and scabs, restoring the barrier. Tissue remains inflamed as healing begins.
42
Describe the inflammatory phase as it relates to micropigmentation
Pigment appears most intense because it is wet and seen through inflamed tissue. Keep the area clean and blot to remove fluids and try to prevent scabbing. A crust/scab may form, but it is important not to pick it as that may remove pigment molecules.
43
Describe the proliferative phase
Begins 2-3 days after injury. New capillaries grow to provide oxygen and nutrients for healing. Monocytes continue to surround pigment molecules and become macrophages when they cannot remove the pigment. Pigment remains encapsulated in the skin. Fibroblasts secrete collagen. Collagen fibers are laid across the wound creating a framework for scar tissue.
44
Describe the maturation phase
Begins 3-5 weeks after injury, can last several weeks and even years. Crust has sloughed off. Dermis has been repaired with or without scar tissue. No signs of inflammation. Pigment molecules placed at the correct depth remain in place.
45
Inflammation of the skin
dermatitis
