As with other parts of the skin scar healing, the forehead skin scar recovery process after removing stitches includes: granulation tissue differentiation and fibrous connective tissue maturation two processes. 1. Granulation tissue differentiation: after the removal of stitches, the granulation tissue has gradually matured, the interstitial water gradually reduced, the surrounding inflammatory cells gradually disappeared, the surrounding capillaries occluded, and gradually produce a large number of collagen fibers, collagen fibers gradually glass-like degeneration, transformed into fibrous connective tissue, making the healed epidermis more solid. 2. Fibrous connective tissue maturation: as the scar becomes more and more solid, the newly born fibrous connective tissue is gradually transformed into aged scar tissue, completely sealing the original wound. After removing the stitches in the forehead area, the wound heals faster because it is small and rich in blood flow. Recovery of traumatic scarring is a complex process and has many influencing factors, and should be directed by a medical professional for recovery.
