When you are experiencing hot flashes, you get a feeling of intense heat spreading throughout your body, starting from the face. For some people, hot flashes can even make them feel faint, sweat and increase heart beat. They last around 2-30 minutes and disappear just as suddenly as they arrived. You may also experience redness on your face or body and your skin can feel hot to touch. This spray uses essential oils as the active cooling ingredient.
