The Pause Cooling Mist is a very unique product with a high level of active ingredients. These ingredients are not harmful in any way but may cause stinging to the eyes. These active ingredients enable us to achieve a significant cooling effect. We opted to keep a high level of efficacy in exchange for potentially some discomfort to the eyes. For the best user experience, we recommend that you shield your eyes before use. Really, the optimal cooling is achieved when the mist is applied to the back of the neck and the wrist pulse points first followed by the face, neck, and chest area.
