Black marks from oil burns are a manifestation of melanin deposition during wound recovery, and whether they can be eliminated needs to be judged on a case-by-case basis, and they may be eliminated if they are not serious; patients with more serious oil burns and who are keloidal generally will not be eliminated. For oil burns are not serious and are not keloid patients, initially after the wound recovery, black marks can appear. But with the passage of time, as well as their own metabolism, melanin deposits will disappear on their own. However, for patients with more serious oil burns and scarring, the fat under the dermis as well as the muscle tissue may be damaged. Thus, the patient may appear blisters, the epidermis may also have the phenomenon of peeling, and then after the wound healing can appear hyperpigmentation, scarring and other phenomena. So generally will not be eliminated. It is recommended that patients with black marks from oil burns should follow the doctor’s instructions for treatment. If there are black marks and long-term not eliminated, you can go to the hospital to do laser treatment to eliminate.
