Patient: Two months ago, my baby was unfortunately scalded by boiling water on his legs, knees, calves and ankles. At that time, the hospital diagnosed it as shallow second degree. The upper knee is more serious. After treatment and wound healing, most of the skin is pink, the texture is the same as normal skin, and there is no difference in touch, but the color is different, just like the tender skin that grows after injury. Only the place about the size of a dollar coin above the knee feels rough, and thick sweat pores can be seen. The skin is very red, slightly protruding and itchy. The wound healed after three weeks, and then it became like this. I have been applying Shubanin for more than a month, and the effect is not obvious. I want to know whether this situation will leave scars and how to prevent it. What about this sulbanine we are using for children now? Many people on the Internet say that skin care works well. Recommend it? When is the best time to prevent scars? Now the baby is only one year old and more than five months old. I don't want him to leave a scar. Is there any way? Li Binbin, Department of Plastic Surgery, Beijing Badachu Plastic Surgery Hospital: The key to scar formation is mainly determined by the severity of the injury: if the injury reaches the dermis, it will generally leave a scar, and the deeper the injury, the heavier the scar. Of course, we can also reduce the formation of scars by taking some positive measures to prevent scars: when we are just injured, we can reduce wound infection as much as possible and speed up wound healing by treating the wound in time; After the wound is healed, you can continue to wrap the wound with elastic bandages, try to brake the joints, and apply some drugs for treating scars externally until the scars soften, so as to reduce the formation of scars. I haven't used sulbanine, and I don't know how it works. Skin care is also commonly used in our hospital, and the effect is good, but the cost of large-scale application will be higher, which may be inconvenient for children to use. You can also use some smears, such as asiaticoside and Kangruibao, and the effect is not bad.
