Generally speaking, normal skin wounds will heal within one to two weeks, and then "new" scars may become red, swollen and hard, fade with time, and finally leave a faint trace, similar to the color of the surrounding skin. Plastic and cosmetic experts in Shanghai Armed Police Hospital reminded that "new scar" is produced after scar excision, so it is necessary to do a good job in nursing new scar, such as paying attention to sun protection in the early months and doing a good job in sun protection at ordinary times to prevent "new scar" from turning red and pigmentation due to sunlight stimulation.

The recovery time of scar resection is related to the depth, direction and area of the scar to be removed, that is, to the difficulty of the operation, and to the nursing and suture methods after scar resection. Recovery time also depends on personal physical problems.
