There is no authoritative information on how long it takes to recover from a blackened burn, but generally it may take about 3 months, so you can’t generalize about the exact time. Scald blackening is mostly considered to be hyperpigmentation after superficial second-degree burns. In general, the wound can be healed within 1 to 2 weeks, usually without scarring, but there can be hyperpigmentation. In addition, black burns may also be third-degree burns, third-degree burns will appear yellow-brown or black-brown scabs, 3 to 4 weeks after the scabs fall off to form a granulation wound, and wound repair depends mainly on skin grafting, in general, it may take about 3 months to recover. However, due to the different condition, physical quality and other factors of each person, so the specific recovery time can not be generalized, there are obvious individual differences. Patients need to strengthen sun protection, use skin moisturizers, and in severe cases or those who have high demands on appearance, phototherapy can be performed to promote the recovery of hyperpigmentation. To summarize, when the occurrence of burns need to go to the hospital in a timely manner, cooperate with the doctor active treatment, strengthen the daily life management, regular follow-up visits, so that doctors can understand the healing of the wound.
