With a broken forehead, the best way to prevent scarring is to avoid infection and promote rapid healing of the skin, making sure to avoid contact with water. If the trauma is large, you need to seek medical attention promptly, and local disinfection and clearing of the trauma will leave a smaller scar. If the wound is small, avoid contact with water and give recombinant human epidermal growth factor gel locally to promote skin healing. After the trauma has healed, it is important to pay attention to sun protection, and topical application of Conradio cream together with Xanadu cream can be used to inhibit the growth of scars. It is best to let the scabs fall off on their own for better recovery. After the scabs fall off, you must pay attention to sun protection to avoid leaving hyperpigmentation or hypopigmentation, which will affect the beauty.
