Normal Scars formation develops according to a rough schedule. During the first few weeks, the scar develops some streght. It usually looks a little pink when the stiches are removed, but is flat. From 3 to 6 weeks, it becomes thicker and often redder, as it gains collagen protein, and it looks it worst during this phase. Then maturation begins that will take about 6 to 18 months, or even longer. During this phase, the scar continues to get stronger but gradually flattens, softens and become pale.
