This is a new type of insect repellent using innovative technology developed by Kao. The serum, with a light texture like body lotion, forms a film that makes it difficult for mosquitoes to land on the skin. It can be used in any situation and features a non-sticky, smooth texture. It does not contain insect repellent ingredients such as DEET or Icaridin, making it safe for people of all ages to use. By applying low-viscosity silicone oil to the skin, it employs mosquito repellent technology that prevents mosquitoes from staying on the skin and inhibits blood-sucking.
