The scar, in fact, is the product of wound healing, and it is a medal left by the best efforts to repair the wound. In the long process of evolution, many tissues of the human body have lost the ability to regenerate, and they cannot be reborn like geckos. As long as the wound is deep and hurts the dermis, it is inevitable to leave a scar.
If left unchecked, the scar may grow bigger and bigger
Because ** is like a mille-feuille cake, only a slight abrasion that hurts the epidermis only needs inflammatory cells to start an inflammatory response to prevent bacteria from invading, plus a hemostatic team - platelets and coagulation factors, which can quickly stop bleeding and coagulation, and can slowly recover. However, once the wound is deep and the dermis is injured, it is a huge project to repair it, and it is necessary to urgently dispatch the epithelial cells and fibroblasts to join and go together before it can be solved.
Light scar, it's not as hard as you think
The wound repair process can be roughly divided into 2 stages.
01 The stage of healing outside the wound: At this time, the focus is on hemostasis and healing. **It will quickly discharge a large number of platelets and immune cells to stop bleeding, clear the battlefield, and allow wounds to heal better and faster.
02 The critical period for the internal healing of the wound to prevent scarring: At this time, the wound seems to have healed on the surface, and the scab has basically fallen off, but the inside has not been repaired. Moreover! This internal repair period is much longer than we think - it may have been half a year since the outer surface of the wound healed, but the internal repair continues.
But many people are confused by the appearance of the outside, thinking that there is nothing serious, so they choose to let it go. In fact, this is the key to whether there will be a scar! Because the internal fibroblasts are still working at high intensity. Day and night, the dermis layer is sewn to form new collagen fibers to fill the interior and support this newly grown **.
Once it accidentally wanders, pushes too hard, and over-stitches, the scar will bulge out and become a hypertrophic scar. What's more troublesome is that at this time, ** is still injured, and he has no strength or energy to lock in moisture. Slowly, the new ** growing in the wound will not only become dry and dry, but even more and more protruding, and the color will be darker than other places.
