Leave the damp cotton bandage for 2-3 hours on until it dries out. Repeat the procedure as often as necessary. The ICE FLUID lasts for about 40 (250 ml) or 15 (100 ml) applications. The application is risk-free. In case of fresh wounds, rashes or eczema first cover it with a foil bandage. Particular care should be taken near the eyes and genitals.
