Furfuranate lotion can usually be washed off after 2 hours of topical application. Furfuranate lotion is an oscillating agent with protective, astringent, drying and antipruritic effects. Because of its cooling effect, it can be used clinically to treat various pruritic disorders such as insect bite dermatitis, prickly heat, urticaria, eczema and contact dermatitis. After being used topically on the affected area, the water gradually evaporates and the affected area is covered with dry stoveganite and other ingredients. After 2 hours, the effect of stoveganite lotion is basically exhausted, and because it affects the aesthetics, it can be removed from the epidermal deposits at this time. Furfuranate lotion is a commonly used topical drug in dermatology, and its irritation is relatively small, but it is not suitable for skin breakouts and oozing. Since the local skin feels cool after topical application, it is not recommended for large areas in winter to avoid systemic symptoms such as colds.
