How to remove black scars from facial boils
A boil, or furuncle, may leave a dark scar after healing. These scars can be removed through various methods such as general care, cold compresses, medication, laser treatment, or surgical treatment. If you have concerns, it is advisable to consult a doctor in advance. Detailed explanations are as follows:

1. General care: Some scars may fade naturally over time, especially superficial and small scars. During this process, it is important to keep the scar area clean and avoid scratching or infection.
2. Cold compress: Apply a cold pack wrapped in a towel to the scar area to relieve tissue congestion and swelling, help constrict blood vessels, and improve the appearance of the scar. However, the duration of cold application should not be too long, usually around 5–8 minutes per session.
3. Medication: Under a doctor's guidance, topical medications such as vitamin E cream, heparin sodium cream, or septilin cream may be used. These medications moisturize the skin, reduce inflammation, promote wound healing, and help inhibit scar formation and fade pigmentation.
4. Laser therapy: Laser light energy can target the skin surface and break down pigmentation within the skin, thereby lightening the scar. Laser treatment usually requires multiple sessions, with the exact number depending on the severity of the scar.
5. Surgical treatment: For large scars or severe scar hypertrophy, surgical removal may be considered. The scar tissue can be excised and properly sutured to improve its appearance. However, surgery carries certain risks, such as infection and swelling, so decisions should be made under a doctor's guidance.
In addition, avoid consuming spicy or irritating foods. Eat more fresh fruits and vegetables, and drink plenty of water to promote skin metabolism and healing.
