In the battle against scars, what is often talked about is how to take care of the treatment after having a scar. Unbeknownst to us, the battle against scars is fought from the moment we suffer a traumatic injury. What can we do to prevent scars before they occur? To discuss this issue, we can use time as a knot point. Whether the wound is healed as a division point, discuss how to prevent scarring at different times, and how to intervene in the first time after the wound has just healed. First, the wound did not heal 1, after the appearance of trauma, the first time to ask a professional surgeon to clean, disinfect, suture or bandage the wound. Careful cleaning of the wound is the most basic to avoid scarring and promote scar healing. Avoiding infection is the most important thing you can do to avoid scarring. Infection will cause damage to the base of the dermis, the epidermis can not be regenerated, so the granulation arrangement can only be added to fill in the gap, which will 100% leave scars. 2, if the wound is small and open, tension exists, easy to form scars. Tension is the main cause of scar proliferation, postoperative tension reducer or no-sew tape. Usually need to use 3 months to half a year. 3, the trauma is more serious and produce larger wounds, need to surgeon for ultra-decrease tension fine suture treatment, effectively reduce the incision skin tension, to ensure that the skin around the scar blood flow, improve the success rate of incision healing, so that the degree of incisional scar hyperplasia to a lower degree, so that the postoperative incision is “flat as the first time”, for car accident scars, cesarean section scar, facial scars, chest scars, and other scars. It has remarkable effect on car accident scars, cesarean section scars, facial scars, chest scars, abdominal scars, limb scars, and so on. The wound has healed. At this time the wound surface has formed the original scar, to be intervened as soon as possible. 1, wound healing will form raised or depressed scars, fractional laser scar removal results are very good, each pulse of laser light emitted is divided into nearly one hundred micro-laser pulses, comprehensive and effective role in the scar structure, precise vaporization of the scar structure decomposition, scar removal targeted, fractional laser action on the skin, the surface of the skin, only the scar part of the skin is subjected to the laser action, the other tissues are not affected in any way, and these When the fractional laser acts on the skin, only the scar part of the skin surface is affected by the laser, other tissues are not affected in any way, and these parts which are not affected by the laser will accumulate more collagen and elastin, which will help the collagen in the dermis to be newborn and rearrange. 2. Pigmentation will appear after wound healing, and the use of photon therapy can effectively remove the pigmentation. Using specific broad-spectrum color light, directly irradiated on the skin surface, it can penetrate into the deep layers of the skin, selective action on the subcutaneous pigment or blood vessels, decomposition of pigmentation, closing the abnormal red blood, while photons can also stimulate the proliferation of subcutaneous collagen. Light energy is absorbed by tissue cells, which can improve cell activity, promote protein synthesis and energy metabolism, enhance phagocytosis of white blood cells, accelerate blood circulation, increase skin elasticity, improve skin yellowish, dull and other conditions, so as to achieve the effect of anti-aging, antioxidant, and skin restoration, which is also known as bioactive light. Prevention first, early intervention, active treatment. It is our combat policy in the battle of scars, finding the right method and targeting the treatment is our combat weapon. I wish you all victory in this battle.
