After suffering from herpes zoster, after active treatment, the condition improves, and the disease is cured when the following characteristics appear: 1. skin lesions: there is a significant improvement, the blisters that appear completely dry up, crust, peel, peel off, and finally leave only hyperpigmented spots, or hypopigmented spots, that is, only brown or white patches are seen clinically; 2. nerve repair: the pain completely disappears, no pain at all, and no Itching, numbness, and weakness are required to confirm that this patient’s herpes zoster has been completely healed. The pigmented or hypopigmented spots left by the lesions that we are concerned about take a longer time to recover, generally taking 3-6 months to return to the normal skin color.
