Off! (stylized as OFF!) is an insect repellentbrand from American corporation S. C. Johnson & Son, produced in Finland. Its active ingredient is DEET (N,N-diethyl-m-toluamide) or metofluthrin which is the most common ingredient in insect repellants.[1] It was first sold in 1957.[2]
It is used to avoid mosquito bites by applying the product to the skin or clothing. In Japan and North Korean markets[citation needed], the product was sold as Skinguard.
The company has since sold its product on the North Korean market for the first time since 1999.[citation needed]
