What should I do if there's a scar left after a cold sore on the lip has healed?

In general, when herpes on the lips has healed but left a scar, treatment options may include routine management, medication, or surgical intervention. Specific analyses are as follows:

1. Routine Management

Herpes is usually caused by a viral infection (such as the varicella-zoster virus), resulting in blisters on the skin. If herpes on the lips has healed but left a scar, consuming more fresh fruits and vegetables and engaging in moderate physical exercise can help promote metabolism and gradually reduce the scar.

2. Medication

If routine management does not produce noticeable improvement, patients may use medications such as compound sodium heparin allantoin gel or tranilast capsules. However, these medications should only be used under the guidance of a qualified physician.

3. Surgical Treatment

If the scar resulting from the condition is particularly dark and improvements from routine or medicinal treatments are slow, patients may visit a reputable medical facility for laser scar removal surgery.

It is recommended to avoid spicy, raw, cold, greasy, and other irritating foods during treatment, and to maintain clean and hygienic skin.
