Many people are left with scars after surgery, and many people often ask, “Why is my incision quite thin and flat when it was just stitched up, and then it slowly raised and became wider? Now summarize the following reasons: 1, congenital physique factors Our body physique varies greatly, if from the reflection of the injury, some people’s congenital physique is not easy to leave visible scars, some people are easy to leave scars or even serious scar growth (such physique is defined as scar physique); the first case of treatment to achieve good results is relatively easy; the second case, after the scar healing In the second case, after the scar is healed, the effect of flattening is worse, or it is more difficult to get a better result. 2.The skin tension on both sides of the suture is found through research, the greater the skin tension on both sides of the suture, the less easy it is to close the wound, and the body will receive the signal of “needing to proliferate tissue”, and more scar tissue cells will grow to bridge the wound, and after a longer period of time, the common “centipede scar” will be formed; On the contrary, if the skin on both sides of the suture is less or no tension, and the skin is tightly matched, the body will not receive a strong signal of “needing to grow tissue” and only need to grow less tissue to heal the wound, so the healed scars are usually linear scars. Non-surgical scar removal will not cause a second injury to the skin, and the repair is smooth and flat, which is the ideal scar removal method. 3, the level of patient cooperation The treatment requires the cooperation of the patient and the conscious and spontaneous action of the patient. After the treatment of scars, birthmarks and moles, the incision will generally have a proliferation period of three to six months, which is also the best period for scar medication to work, so we recommend that patients should apply scar growth inhibiting proliferation medication; then again, they should avoid spicy and other foods (chili, soy sauce, seafood, etc.) during the proliferation period. All these are done spontaneously out of the supervision of the doctor. Both scar growth inhibiting drugs and spicy foods have a slow cumulative effect on the scar of the incision, with no significant change in a relatively short period of time, but after six months, the more pronounced scar growth will seriously affect the effectiveness of the treatment. Throughout the three factors that affect the effect of scar treatment, the first factor is a congenital determinant, a fundamental factor in the treatment of scars, which we cannot change; if we can determine that there is a problem with the physique before treatment, we will definitely choose effective auxiliary treatment means. The second factor and the third factor are factors that we can control artificially by choosing the best treatment plan and insisting on post-treatment medication to increase the possibility of obtaining the best treatment effect.
