Hyperpigmentation usually disappears in about six months to a year after a facial abrasion. It varies according to individual conditions. As the face is exposed to the environment for a long time, the wound will be aggravated by the wind and sun during the healing process, and the hyperpigmentation will disappear in half a year to a year after the wound heals. Patients with facial abrasions should pay attention to sun protection in daily life, which can effectively reduce hyperpigmentation. After facial abrasion, the wound should pay attention to keep clean, to avoid prolonging the healing time due to repeated infection, aggravating hyperpigmentation. After the face is traumatized, those with minor abrasions can immediately use saline to rinse the wound and then disinfect it with iodophor. Serious cases need to go to the hospital for wound treatment.
