4 Spray in direct contact with the area to be treated in the case of small skin cracks, or at a distance of approximately half a centimetre in the case of medium/large skin cracks. The spray dries on the skin in 40 seconds and forms a protective film, similar to a transparent, water-repellent plaster. Each spray delivers the single dose required for one dressing. Repeat the process for further cover if necessary. Repeat the application once a day.
