How long it takes for an abrasion to heal depends largely on the severity of the abrasion. If the abrasion is superficial, it usually takes 3 to 5 days to heal; if the abrasion is deeper, it takes about half a month to a month to heal. 1. Superficial abrasions: If the patient’s abrasions are particularly superficial, involving only the surface layer of the skin, this situation generally does not require special treatment, due to the skin’s self-healing function, it generally takes 3 to 5 days to heal. 2. Abrasion parts deeper: if the abrasion parts deeper, involving the deep dermis and the whole skin layer, this time the healing time is relatively long, about half a month to 1 month lesions to heal. At this time, you can use some antibiotic ointment, such as fusidic acid cream, mupirocin cream and so on, or to be cleaned up, change the treatment. When the patient’s skin is seriously abraded, it is recommended to go to a regular hospital for timely examination and symptomatic treatment under the guidance of a professional doctor.
