Potassium hydroxide is a strong alkali that has long been known to digest proteins, lipids, and most other epithelial debris of skin scrapings to identify fungal infections. Topical 10% potassium hydroxide aqueous solution applied twice daily on each molluscum contagiosum lesion until all lesions undergo inflammation and superficial ulceration may be effective in clearing molluscum contagiosum in children.
