[Research advances on the effect of early intervention on post-traumatic scar formation]

Scars caused by trauma will not only affect the appearance and cause dysfunction, but also affect the quality of psychological life of the patients to varying degrees. With the in-depth understanding of the process of scar formation after trauma and the continuous development of related intervention methods, early intervention within 3 months after trauma has been proved to be able to promote wound healing, inhibit scar hyperplasia, and interfere with the natural remodeling of scar collagen. This review summarizes the process of scar formation after trauma, as well as the timing and method of early intervention.
