Our Spray works in two different ways. First of all, the Spray contains 15 natural oils and extracts that instantly soothe the skin and reduce itchiness such as cooling oils like peppermint, eucalyptus and rosemary. Secondly, due to these natural ingredients, the Spray is incredibly rich in vitamins and minerals that sink deep into the skin, targeting young skin cells. As these cells mature and come to the surface, they will have become stronger and more able to fend off future flare ups. These long-term effects usually become noticeable after 2-4 weeks.
