Supports the maintenance of a healthy skin and coat. The Duo- Complex of nourishing Aloë Vera and dimethicone immobilizes ticks, fleas and other parasites such as mosquitoes, mites and lice through purely physical means. Beaphar Dimethicone Line-On does not contain (chemical) insecticides, but silicones (dimethicone) that form a sticky layer around ticks, fleas, mites, etc. Because of this, they will be paralyzed and will not be able to move anymore. The parasites will fall from the coat or can be brushed off of it.
