Scalding healing long scars is the result of the body’s self-repair, is due to the skin dermal cells damaged fibroblasts strong regeneration and the formation of hyperplastic scars. After the skin burns the human body will carry out self-repair, wound healing due to the dermal cells are damaged, with a strong ability to divide and regenerate fibroblasts are stimulated to rapidly carry out a large number of divisions and proliferation, synthesize a large number of excessive collagen fibers, laying in the dermal cells to the epidermal cells to fill in the wound between. Newly developed granules at the wound replace the original tissue, and the wound heals. Due to the rearrangement of collagen fibers, the wound appears different from the surrounding skin and lacks texture, i.e., a scar. It is normal for scars to grow after a burn has healed, but if discomfort occurs, seek medical attention.
