When a baby falls and bleeds from a bump on the head and face, parents often make the wrong move by being rushed and panicked, leading to obvious scarring later. The correct approach should be as follows: First, you should use a clean towel, clothing or cotton cloth to compress the wound, and then take it to the nearest hospital to determine the extent of the injury. Avoid touching the wound with RMB, medication powder or other dirt. Secondly, when choosing a suture in the hospital, you should try to choose cosmetic sutures and use imported sutures such as Priligy and Vyjo as much as possible when economic conditions allow. Do not let wounds that should be sutured heal naturally for fear of scarring. After the wound is treated, tetanus prophylaxis injection and antibiotic treatment, light diet, prevention of wetting and sweating, regular medication changes and stitch removal on schedule should be given. After the wound heals, if the local skin becomes red, swollen, higher than the skin surface, painful and itchy, it is a proliferative scar, and topical products can be used to control the pain and itch, inhibit scar proliferation, and promote scar maturation, such as Conrad, cumene cream and other drugs for topical use, or silicone film sheet or silicone gel can be used for topical application. It takes some time for the scar to recover, 1-3 months for short cases and 1-2 years for long cases. The criteria for a stable scar are: no itching, flattening, whitening and softening. If scar reshaping treatment is needed, wait until the child is more than 10 years old, preferably when he/she is able to cooperate with the treatment at the age of 16 or 7, and different options can be chosen according to the situation at that time. If the scar area is large, expander flap repair surgery can be performed; if the area is small, excision suture or local flap transfer surgery can be performed; if the scar is obviously straight, treatment such as sawtooth reshaping + grinding or laser can be performed to make it fade, but no method can completely eliminate the scar. In conclusion, scarring on the face is nowadays treated by various means and new technologies are emerging. Although the original appearance cannot be restored, a better appearance can be achieved through plastic treatment and makeup modification.
