When will the black marks left by minor burns heal?

The black marks left by minor burns usually take weeks to months to fade away, depending on the individual's skin repair ability. Treatment can speed up recovery through topical medications, sun protection and diet.

1. Topical medications: Using skin care products containing vitamin C, vitamin E or hydroquinone can help reduce pigmentation. Vitamin C has an antioxidant effect and can inhibit melanin production; vitamin E can promote skin repair; hydroquinone is a skin whitening ingredient, but it must be used under the guidance of a doctor.

2. Sun protection measures: Ultraviolet rays will stimulate the production of melanin and delay the fading of dark marks. When going out, you should apply sunscreen with SPF30 or above, wear a hat or use a parasol to avoid direct sunlight.

3. Dietary adjustment: Eat more foods rich in vitamin C and vitamin E, such as citrus fruits, kiwis, nuts and dark green vegetables. These nutrients help skin repair and anti-oxidation.

4. Skin care: Keep the affected area clean and avoid friction and irritation. Use mild moisturizing products to promote skin barrier repair.

5. Consult a doctor: If the black marks persist for more than 6 months without improvement, or are accompanied by pain, itching and other symptoms, it is recommended to consult a doctor in time. The doctor may recommend the use of more powerful whitening products or laser treatment.

Black marks left by minor burns are a normal part of the skin's repair process and can usually fade away with proper care and conditioning. Patience and scientific care methods can help speed up the recovery process. If symptoms persist or worsen, seek professional medical help in time for more effective treatment options.
