That's a good idea. We sometimes spray mist when our faces are dry. Mist moisturizes our skin and we can look young. And the effect of mist is to cool the skin as it becomes dry from the skin Perhaps the principle of this product is this. When water vapor is released from the chest during outdoor activities, it can dry up and lower body temperature. Thank you for introducing me to a good product. But the price of the product seems to be a bit high.
