The present application discloses novel endohedral fullerenes having enclosed therein one or more ozone molecules, e.g. fullerenes selected from Cso-fullerene (Buckminsterfiillerene), C7o-fullerene, C76-fullerene, C78-fullerene, C82-fullerene, C84-fullerene, and Cuo-flulerene. The application further discloses a composition comprising the endohedral fullerene and a carrier material, e.g. where the carrier material is a skin lotion, such as a skin lotion comprising L-ascorhic acid or Vitamin E. Moreover, various uses of the novel fullerenes are disclosed, e.g. for skin UY-protection in or on the surface of sun glasses in or on the surface of window glass in or on the surface of textiles, fabrics, clothes, wood, paint, paper, cushions, leather, hair-care products, and plants.
