The Ratok®therapy: the focused punctiform microphototherapy of vitiligo. The therapeutic introduction of the Ratok®derm equipment, protected by an international patent, has solved most of the problems resulting from total body UV irradiation, from combination with drugs – which sometimes cause toxic reactions following up on-going intake - and from a difficulty to control the quality and quantity of UVB rays used. The Ratok®therapy, enabled by such equipment, consists in a punctiform and focused microphotoirradiation with high UVB-content rays  (Fig. 14 and Fig. 15) at such doses and wavelengths as to stimulate repigmentation of vitiligo patches; this occurs without interfering with the normally pigmented skin and absolutely giving up the use of any supporting therapies  (Fig. 16). A further exceptional and specific benefit of the Ratok®therapy is provided by the combined reaction of patches close to the treated vitiligo areas; such phenomenon brings about repigmentation of these achromic regions and, often, even of vitiligo patches located very far away from the treated ones (Fig. 17). This is due to the high molecular density of skin layers, promoting transfer of the light energy absorbed by one region to all close-by regions, as well as to many remote ones. The Ratok®therapy has no contraindications and produces no side reactions. Unlike commonly used phototherapies combined with photosensitizing agents, the Ratok®therapy may be performed on children: excellent to moderate results were obtained in 100% of cases treated during a five-year study (1990-1995) on this age group.
