Shingles is usually less likely to scar with prompt treatment, but there is a risk of scarring if left untreated or for specific reasons. Herpes zoster is an infectious disease affecting the nerves and skin caused by varicella-zoster virus infection. It can appear as clusters of papules and blisters, which can cause damage to the skin and may result in temporary erythema, hyperpigmentation or scarring after the rash subsides. After aggressive antiviral treatment and nerve-nourishing medications, the lesions can be largely recovered without scarring, but some particularly large, heavily infected, and untreated herpes can leave scarring, especially in keloid patients. In addition, some patients with severe disease can form large or bloody blisters, and scratching with the hands during this period can cause the herpes to break down and become infected, resulting in ulcers of varying depths and the possibility of atrophic scarring. When herpes zoster is found, it should be treated with antiviral medication under the guidance of a doctor, along with topical creams, and if a bacterial infection occurs, antibacterial medication should be actively used, without scratching.
