Description

technical field [0001] The invention relates to the medical and health field, in particular to a preparation method of a wound dressing for removing scars. Background technique [0002] "Scar" is the damage of physical, biological, chemical and other factors on the human skin and soft tissue, resulting in serious damage to the skin and soft tissue, which cannot be fully repaired normally by itself, and is replaced by fibrous tissue. Local symptoms that affect both appearance and function . Scar is an inevitable product in the process of human wound repair. In a broad sense, there is no wound healing without scar. The production and deposition of scar tissue collagen increases wound strength and is generally beneficial. However, compared with the tissue before the injury, the scar still has certain defects. From a mechanical point of view, its resistance is weakened; from a nutritional point of view, it causes obstacles to the exchange of oxygen and nutrients; from a funct...
