If the lateral incision is made during the normal delivery, then the scar tissue appears to be hyperplastic, and in this case, you can apply local scarring spirit to reduce the occurrence of hyperplasia. It is also recommended to keep the vulva clean after the lateral incision to avoid local scar growth due to inflammatory reaction. Once the scar growth is more pronounced, it is likely to be caused by keloid. If the local discomfort of the vulva is serious due to scar growth, or if the function of the vulva is affected by scar contracture, scar excision surgery or laser treatment can be performed, mainly to reduce the local proliferation of the scar and then to achieve local softening.
